Regarding cancer, there are always various popular opinions. Some seem to be reasonable, but in fact they are scientifically wrong, especially when these opinions have some theoretical basis, it is easy to mislead patients. For example, getting cancer is tantamount to getting a terminal illness. If the cancer is not cured, it will be better. If the tumor is cut, everything will be fine, teaching you how to starve cancer cells, and so on.
But I'm afraid of going back. In the face of cancer, there are many things we can do, at least we should not be fooled by these rumors. The American Cancer Institute released the latest scientific information on the most common misconceptions about cancer. We together look!

24. What should we do about cancer rumors?
1. Is cancer a death sentence?
Answer: No.
In the United States, the number of deaths from cancer has steadily declined since the 1990s. The five-year survival rate for some cancers (such as breast, prostate and thyroid cancer) is now 90% or higher. The current 5-year survival rate for all cancers is approximately 67%.
11 of the 18 most common cancers in men showed reduced mortality, including leukemia, melanoma, myeloma, non-Hodgkin’s lymphoma, colon/rectal cancer, esophageal cancer, kidney cancer, laryngeal cancer, lung cancer, and bronchial cancer , Prostate cancer and stomach cancer. Among them, the mortality rate of lung and bronchial cancer decreased the most.
Fourteen of the 20 most common cancers in women showed reduced mortality, including leukemia, melanoma, non-Hodgkin’s lymphoma and bladder cancer, breast cancer, cervical cancer, colon/rectal cancer, esophageal cancer, and gallbladder Cancer, kidney cancer, lung cancer and bronchial cancer, oral cancer and pharynx, ovary and stomach. Among them, the mortality rate of non-Hodgkin's lymphoma decreased the most.
However, it is important to note that these data are based on the results of extensive research. How long a cancer patient will live and whether he or she will die from the disease depends on many factors. Individualization varies greatly, including whether the cancer is growing slowly or rapidly, the extent to which the cancer spreads in the body, and whether there are effective treatments. People’s overall health and so on.
2. Will eating sugar make my cancer worse?
The answer is no.
Although studies have shown that cancer cells consume more sugar (glucose) than normal cells, no research has shown that eating sugar will make your cancer worse, or if you stop eating sugar, your cancer will shrink or disappear.
However, a high-sugar diet may cause excessive weight gain, and obesity has been shown to be associated with an increased risk of the following cancers.
The National Cancer Institute confirmed obesity and endometrial cancer, esophageal adenocarcinoma, gastric cardia cancer, liver cancer, kidney cancer, multiple myeloma, meningioma, pancreatic cancer, colorectal cancer, gallbladder cancer, breast cancer, ovarian cancer, and thyroid Increased risk of cancer is closely related.
You may not know why obesity causes cancer:
3. Can artificial sweeteners cause cancer?
The answer is no.
Researchers have studied the safety of artificial sweeteners (sugar substitutes) saccharin (Sweet'NLow®, SweetTiter®, NectaSweet®); sodium cyclamate; aspartame; acesulfame potassium; sucralose, currently So far, no evidence that they cause cancer in humans has been found. With the exception of cyclamate, all these artificial sweeteners have been approved for sale by the US Food and Drug Administration. It needs to be added correctly in accordance with the national scope of use and dosage standards.
4. Is cancer contagious?
Generally speaking, no.
Cancer is not an infectious disease that spreads easily from person to person. The only situation is that cancer can spread from one person to another during organ or tissue transplantation. People who receive organs or tissues from donors who have had cancer may have an increased risk of transplant-related cancers in the future. However, this risk is extremely low-two in every 10,000 organ transplants. Avoid using organs or tissues from donors with a history of cancer.
In some people, cancer may be caused by certain infectious viruses (such as certain types of human papillomavirus (HPV)) and bacteria (such as Helicobacter pylori). Although viruses or bacteria can spread from person to person, the cancer they cause cannot be spread from person to person.
Certain infectious agents, including viruses, bacteria and parasites, may cause cancer or increase the risk of cancer formation. Such as:
5. Does my attitude determine the risk and prognosis of cancer?
We often say that people with cancer personality are more likely to get cancer. Is this true? To date, there is no convincing scientific evidence that a person's "attitude" is related to his or her risk of cancer. If you have cancer, you sometimes feel sad, angry or discouraged. This is normal.
People with a positive attitude may be more likely to maintain a normal life. Exercise and emotional support can help you cope with cancer.
The obvious connection between people with excessive psychological stress and cancer may appear in many ways. For example, people under stress may exhibit certain behaviors, such as smoking, overeating or drinking, which increases the risk of cancer.
Some data do show that when cancer patients are stressed, they will feel helpless or desperate. This response is associated with a higher mortality rate, which may be because negative emotions make them feel helpless or desperate, do not seek treatment when they are sick, give up or fail to comply with potentially useful treatments, involve dangerous behaviors such as drug use, or Not maintaining a healthy lifestyle, etc.
6. Can cancer surgery or tumor biopsy cause cancer to spread in the body?
The answer is that surgery or puncture is extremely unlikely to cause cancer to spread to other parts of the body.
Following standard procedures, surgeons use special methods and take many measures to prevent cancer cells from spreading during biopsy or surgery. For example, if they must remove tissue from multiple areas of the body, they use different surgical tools for each area. Therefore, what we should worry about is not the metastasis caused by surgery or puncture, but the process of the metastasis of these cancer cells:
Common sites of different cancer metastases
7. Can mobile phones cause cancer?
The answer is no.
People worry that mobile phones cause cancer mainly because they emit radio waves, which is a non-ionizing radiation. The tissue closest to the antenna can absorb this radiation. Cancer is caused by genetic mutations, and the non-ionizing radiation emitted by mobile phones will not damage the low-frequency energy of genes.
So the real carcinogens in daily life are high-frequency electromagnetic fields (ionizing radiation), including X-rays and gamma rays. These electromagnetic fields are located in the ionizing radiation part of the electromagnetic spectrum and can damage DNA directly or cells.
The low-to-medium-frequency EMF includes electrostatic fields (electric or magnetic fields that do not change with time), magnetic fields of wires and appliances, radio waves, microwaves, infrared radiation and visible light. These EMFs are in the non-ionizing radiation part of the electromagnetic spectrum and do not directly damage DNA or cells.
The electromagnetic spectrum shows all possible electromagnetic energy frequencies. It ranges from extremely long wavelengths (extremely low frequency exposure, such as power lines) to extremely short wavelengths (X-rays and gamma rays), including non-ionizing radiation and ionizing radiation. The left side of the dividing line is non-ionizing radiation that is not carcinogenic to the human body, and the right side is ionizing radiation that is clearly carcinogenic.
8. Are there any herbal products that can cure cancer?
Although some studies have shown that alternative or complementary therapies (including some herbal medicines) may help cope with the side effects of cancer treatment, so far no herbal product can effectively treat cancer. In fact, some herbal products may even be harmful when taken during chemotherapy or radiation therapy because they may interfere with the effects of these treatments. Cancer patients should consult their attending doctors and authoritative Chinese medicine practitioners on whether complementary and alternative therapies, including vitamins and herbal supplements, can be used during treatment.
The NCI Office of Cancer Complementary and Alternative Medicine (OCCAM) once hosted a conference titled "Traditional Chinese Medicine and Cancer Research: Promoting Cooperation" to collaborate on the following research:
Chinese anti-cancer drugs, especially the formula and compound Kushen injection between the CCR/NCI Molecular Immunomodulation Laboratory of the Chinese Academy of Chinese Medical Sciences and the Cancer Institute of the Chinese Academy of Chinese Medical Sciences (CACMS)
The effect of berberine, a natural product from Chinese herbal medicine, on the inhibition of colon cancer
Effect of resveratrol mouse model on preventing tumorigenesis
Chemopreventive study of ginsenoside, compound K, American ginseng, Dan Shen (Dan Shen) and Oplopanax horridus. These studies were carried out between the Tang Center at the University of Chicago and the China University of Pharmacology
The safety and pharmacokinetics of the herbal formula based on astragalus, namely Ji Fukang Kang for non-small cell lung cancer patients between Memorial Sloan Kettering Cancer Center and Shanghai University of Traditional Chinese Medicine
As well as acupuncture and moxibustion treatment of cancer symptoms management.
9. If my family member has cancer, can I also get cancer?
Not necessarily.
Cancer is caused by genetic mutations. Only about 5% to 10% of cancers are caused by harmful mutations inherited by a person’s parents. In families with hereditary cancer-causing mutations, multiple family members usually suffer from the same type of cancer. These cancers are called "familial" or "hereditary" cancers.
The remaining 90% to 95% of cancers are caused by mutations that occur during the life of an individual. These mutations are the natural result of aging and exposure to environmental factors such as tobacco smoke and radiation. These cancers are called "non-hereditary" or "spontaneous" cancers.
So how do you know if you have inherited cancer-causing mutations? It can be assessed by genetic testing. The following list includes some of the most common hereditary cancer syndromes that can be used for genetic testing, the genes mutated in each syndrome, and the types of cancer most commonly associated with these syndromes.
However, it should be noted that even if there are cancer-susceptible mutations in the family, it does not necessarily mean that everyone who inherits the mutation will develop cancer.
10. Can antiperspirants or deodorants cause breast cancer?
The answer is no.
So far, the best studies have found no evidence that chemicals commonly found in antiperspirants and deodorants are related to changes in breast tissue.
11. Will the use of hair dye increase the risk of cancer?
There is no convincing scientific evidence that the use of personal hair dyes increases the risk of cancer. However, some studies have shown that hairdressers and hairdressers who are regularly exposed to large amounts of hair dyes and other chemical products may increase the risk of bladder cancer.
12. Can you prevent cancer by eating more anti-cancer foods?
Nowadays, more and more people are keen on dietary supplements. Some foods are also labeled as anti-cancer and anti-cancer. Simple foods such as garlic, potatoes, and sweet potatoes are on the list. Widespread rumors encourage everyone to eat more of this kind. food.
These rumors actually lack scientific basis. What's more, the balance of nutrients intake by the human body is crucial to the stability of the body's environment, and a single food type can easily cause nutritional imbalance. Anti-cancer foods must first comply with the laws of nutrition before they can stand the test of time.
13. Can microwave hot food cause cancer?
There is no doubt that the nutritional content of leftovers is much lower than that of fresh vegetable rice. Some foods may deteriorate, produce harmful substances, and pathogenic microorganisms may breed.
Some people attribute the harm caused by eating leftovers to microwave heating, but they wrongly believe that microwave heating of food is only a physical heating method, and the effect on nutrient components is not significantly different from other high-temperature heating methods. Evidence suggests that microwave-heated food is more likely to cause cancer.
14. The treatment of advanced cancer is also useless?
Whether the patient is in the early stage or advanced stage of the tumor is one of the most concerned issues for tumor patients and their families. Many patients give up active treatment after confirming that the tumor is advanced. But advanced tumors are not without therapeutic value. In fact, most patients with advanced tumors can improve their quality of life through treatment.
Some patients survive with tumors, some patients have reduced lesions, and some patients have significantly improved quality of life. These are the values of treatment for advanced cancer patients. Even in the future, with the advancement of medicine, tumors will have a chance of being completely cured.
15. Chemotherapy not only kills cancer cells, but also normal cells?
Chemotherapy is one of the important methods for the treatment of tumors, and it is often mentioned that chemotherapy may damage normal cells. The effect of chemotherapy drugs on bone marrow hematopoiesis and liver and kidney function is objective. Whether patients can receive chemotherapy must be evaluated by professional physicians.
But many cancer patients will be dominated by this kind of remarks, because they are worried about greater physical damage and give up chemotherapy.
In fact, after evaluation by professional physicians, chemotherapy, as an effective method of tumor treatment today, has far less adverse effects on the body than its tumor treatment, and its advantages outweigh the disadvantages.
16. Can vegetarianism prevent cancer?
Regardless of whether it is vegetarian or non-vegetarian, a reasonable diet, avoid partial or picky eaters, and maintain a balanced nutrient in the body is the key to good health. If you follow the rumor that a vegetarian diet can prevent cancer, it will lead to nutritional imbalance in the body, which can cause various diseases.
What needs to be reminded is that if you have cancer, don't panic. Nowadays, the detection rate of tumors is continuously increasing, and the proportion of early tumors is also rising. Most early tumors can be cured. In addition, new treatment methods, such as immunotherapy, biological therapy, targeted therapy, etc., have been continuously developed and applied to the clinic, achieving good results, and the cure rate of tumors will continue to increase in the future.
17. "Purely natural and pollution-free"
We tend to think that artificial things are not good, but natural things are good. But in fact, if you think about it carefully, our ancient poisons are all natural.
To give an example, many people may not know what aristolochic acid is, it is a compound. How was it discovered in the first place? It is because suddenly a group of women in Belgium suffered from acute renal failure inexplicably. Later, a study found that they were all eating a Chinese herbal medicine to lose weight and ate too much.
The Chinese herbal medicine was later found to contain aristolochic acid. Will it be a problem if I eat low-dose aristolochic acid? There are also problems because it can directly stimulate gene mutations. In fact, aristolochic acid is one of the most mutated substances among the known compounds in the world, even surpassing smoking.
The mutation caused by aristolochic acid can now be found through genetic testing, which means that if you give me a cancer patient, I can tell you if he has taken medicine containing aristolochic acid.
China is an area with a high incidence of liver cancer, and more than half of the world's liver cancer patients are in China. There is a particularly serious problem here, that is, we have very many hepatitis B virus carriers. Unfortunately, many people eat some Chinese herbal medicines to protect the liver. As a result, this Chinese herbal medicine contains aristolochic acid, which causes double stimulation to him.
Some recent studies have found that a large proportion of liver cancer patients in China carry such aristolochic acid mutations.
18. Go to the hospital and die faster.
Some time ago, there was a heated discussion on the Internet. There was a very young actor born in the 90s who had lymphoma.
In fact, the effect of regular treatment of lymphoma is relatively good. But she was very scared, so she heard the people around her saying that we don't want to go to the hospital anymore, and look for an old genius doctor in a certain rural village in Yantai, Shandong. After she went, the old genius doctor used cupping and acupuncture to treat her cancer. This was a purely natural treatment, but unfortunately, she died soon.
When she was sent to the hospital for emergency treatment, there was no other way. What's the most regrettable thing is that she didn't actually die of cancer in the end, but a serious infection caused by cupping and acupuncture.
Because after she got lymphoma, the immune system in her body is already very weak. At this time, cupping caused the capillaries to rupture, which is very easy to be infected. In the photos she took when she finally arrived at the hospital, her hands were black and very painful. Later, her sister posted a Weibo. I found it very convincing. She said that the third sister finally started receiving chemotherapy from Western medicine, but she was tricked into receiving chemotherapy until now.
19. It is called acidic constitution causing cancer.
How many people have heard of this thing? How many people think they are very sour? Acidic body carcinogenesis is a very interesting theory, it tells you three points.
First, the normal blood pH is 7.35 to 7.45. Is there a problem with this? No problem, all the first words of pseudoscience are scientific.
The second is that if our PH value is less than 7, we will die. There is no problem with this sentence. But if you have had a physical examination, do you carefully read your blood checklist. Does it contain the PH value? No, because the test is also a white test, which is as high as 7.35 to 7.45.
But he tells you that if your body is dysfunctional, you will be acid from healthy to sub-healthy, and acid+ and acid++ from illness to death. The more sour, the faster you will die. Then someone will ask, what Are you sour? He said there are two ways, don't worry. This is a consistent method of pseudoscience and it is very strong.
The first one is feeling about yourself. If you feel bad, "long-term physical exhaustion, fatigue easily, and haggard," you will be sore. Everyone here is laughing, because our quality is a little higher.
The second one is very deceptive. If you don’t believe me, I’ll send you a pH test paper for free. Get up and test your saliva in the morning for three consecutive days. If it is lower than 7, you have an acidic physique.
Is there any problem with this? A concept is secretly changed, blood becomes saliva. What is the normal pH of saliva? It is 6.8 to 7.1, so as long as you dare to test, you must be acidic. Many people were scared to death after the test. It is really fortunate to say that they are so sour and not dead. You have to go to Taobao to buy something as soon as possible.
Acidic physique is a very strange theory, because we Chinese medicine does not have this theory, and Western medicine does not have this theory, so why does it appear? On all online platforms, you can search for lower-row acid products and get a feel for it.
Why do those of us who dispel rumors always fail to dispel those who spread rumors? Because we are refuting rumors part-time, and others are spreading pseudo-science full-time, the first thing when others get up every morning is thinking about how to spread this pseudo-science, how can we get them?
20. Starve cancer cells.
Its theory is that cancer cells grow very fast, and they especially like sugar, so let's not eat and starve them to death.
This thing seems to be reliable when I think of it, but there is a problem. Cancer cells like sugar, but many cells also like sugar. For example, our brain nerve cells and our immune cells are usually starving to death. Before the cell, you have starved to death.
It's like saying that we have too little salary every month and too much tax. Do you think the method you should adopt is to pay more or pay less? You might as well pay more money and everyone will live a little better.
In China, 20% to 30% of patients end up starving to death. Really, no kidding. Nutritional support is now a very important part of the treatment in the United States. China is still very backward in this regard. But fortunately, some experts have already begun to appeal that we will do more in this regard. I hope that in the future, everyone will not blindly believe in starving cancer cells. Cancer patients really want to eat well.
21. More people die from cancer treatment than directly from cancer
I heard this statement when I was very young, and it is especially popular in some areas where medical science is relatively backward and relatively closed. In fact, this kind of thinking of the people in these areas can be understood. After all, for them, the lesson of the loss of wealth and wealth is too terrible, and the shadow of the snake is extremely helpless. However, understanding does not mean it is right. The claim that chemotherapy "only 3% works" circulated on the Internet is misunderstood, and the source of information is outdated. More and more cases have proved the therapeutic effect of anti-cancer drugs on cancer. For example, due to the application of the anti-cancer drug cisplatin, the cure rate of testicular cancer has increased from less than 70% in the 1970s to 96% now; while chemotherapy has increased the cure rate of children with cancer from approximately 25% in the 1960s. Increase to the current 75%.
Of course, we must know that whether it is traditional surgery, chemotherapy, radiotherapy or the emerging immunotherapy, targeted therapy, cell therapy, etc., it is impossible to have no damage to the body at all. Especially traditional radiotherapy and chemotherapy, while killing cancer cells, inevitably cause greater damage to normal cells, so adverse reactions and side effects are more serious. In addition, it is very difficult to cure patients with advanced cancer because the cancer cells have spread throughout the body. Although cancer treatment can relieve symptoms and extend the life of patients, it is unlikely to "cure" advanced cancer. If detected early, surgery is still the most effective way to treat cancer. However, more people are treated with radiotherapy than with anticancer drugs. However, the role of chemotherapy and other anti-cancer drugs in cancer treatment is still very important, sometimes to treat the cancer itself, sometimes to help extend life. What everyone must understand is that for patients with terminal cancer, the purpose of treatment is to relieve symptoms and prolong life as much as possible, which is often referred to as "palliative care" rather than "cure" these patients. After receiving treatment, patients can have the opportunity to prolong life, relieve pain, and wait for the hope of life-saving. Without treatment, patients will not only wait for death, but will also make the final stage of life hopeless and painful. As for which choice has a higher quality of life, the benevolent sees the benevolent and the wise. However, the balance between length and quality of life is a difficult choice that every cancer patient and his family must make.
22. Cancer cells have a soft spot for sweets
One day when the editor of a hypoglycemic patient threw sugar into her mouth, a kind-hearted aunt persuaded the editor: "Girl don't eat so much sugar, you will get cancer." The editor expressed helplessness. The editor is not a cancer patient. Obesity is abruptly read to spit out sugar is also very exhausting. Later, the data told the editor that the rumors that "sugar can nourish cancer cells" spread staggeringly. Many people believed in it and actively practiced the "true knowledge" of "cancer patients eliminate sugar". The editor was tired again.
"Sugar" is a collective term, which is a series of molecules, including the monosaccharides (glucose, fructose) naturally occurring in plants. We usually use sucrose for cooking and seasoning, which is composed of glucose and fructose through chemical bonds. Sugars are also called carbohydrates because their molecules are composed of carbon, hydrogen and oxygen.
Carbohydrates are hydrolyzed into glucose and fructose in the human digestive system, and then absorbed into the blood, and then enter the cells as raw materials for respiration to provide us with energy. All cells in our body, whether cancerous or not, need glucose to provide energy. Since cancer cells tend to grow faster than normal cells, cancer cells have a greater demand for glucose. In addition, there is evidence that the metabolic pathways by which cancer cells break down glucose production are also different from normal cells. Researchers are conducting research on the pathways of carbohydrate metabolism in cancer cells and hope to find more effective cancer treatments.
However, this does not mean that unlike carbohydrates in other foods, the sugar in sweets will be exclusively used by cancer cells. Our body does not decide which specific cell should receive which nutrients. Most of the carbohydrates we eat will be converted into glucose, fructose or other small molecule sugars to supply those tissues that need energy. In order to maintain a healthy diet and prevent gaining weight, of course we should limit the intake of sugary foods, but this is completely irrelevant to "sugar-sweetened foods specifically providing nutrition for cancer cells".
23. Antioxidants are anti-cancer experts
Vitamin C is probably the most famous antioxidant. You may have heard that it is anti-cold and anti-cancer. The author of this claim is Pauling, the winner of the Nobel Prize in Chemistry and the Peace Prize. However, subsequent clinical trials at the famous Mayo Clinic in the United States rejected the claim that vitamin C can treat cancer. In recent years, studies have pointed out that vitamin C may interfere with the efficacy of some chemotherapy drugs. The US Food and Drug Administration (FDA) also pointed out that there is no scientific evidence or important research to prove that vitamins have the effect of preventing colds.
In addition to vitamin C, the potential hazards of other antioxidants have gradually become clear with the in-depth research. Research in the New England Journal of Medicine shows that vitamin E and β-carotene not only cannot reduce the incidence of lung cancer in smokers, but significantly increase the incidence of lung cancer. Another large-scale randomized controlled study in the United States obtained similar results: intake of β-carotene and vitamin A will increase the incidence of lung cancer and cardiovascular disease mortality. In recent years, some authoritative medical journals such as "The Lancet" have successively published many studies, showing that some antioxidants not only have no protective effect on common cardiovascular diseases and cancer, but have various unexpected harmful consequences, increasing Disease risk and mortality.
Human life activities are complex and relatively stable. Antioxidants sound beautiful, but a certain balance must be maintained between multiple antioxidants to be effective. Moreover, being effective in the laboratory cannot be completely equivalent to being effective in the human body. Regarding the intricate relationship between free radicals and antioxidants, the current findings are only the tip of the iceberg. There are many complex life activities involved. It may not be wise to break the balance maintained by the body without authorization.
Pauling’s arrogance in the battle over the function of vitamin C made various health care products manufacturers laugh from ear to ear. To this day, various vitamins and trace element supplements with antioxidant effects are still regarded by the public as “health products”. The voices from the medical profession that they are harmful and useless are rarely heard. This editor must still emphasize the medical advice: in the absence of malnutrition or various chronic diseases due to lack of vitamins, trace elements, etc., no additional supplements are necessary at all. Even if you really need it, instead of taking the risk to spend the wrong money on health products, it is better to buy vitamins as medicines as prescribed by your doctor. After all, the purity, activity and safety standards of this vitamin are much higher than so-called health products.
24. What should we do about cancer rumors?
In addition to these things pointed out by the editor, there are many stunned cancer rumors, and even more frightening is that many people believe. In fact, many cancer rumors have something in common, that is, they lack sufficient medical evidence. The so-called medical evidence is not the white hair of the "experts" in the advertisement, or "I have a friend who studies medicine said", or "someone who had the same disease as you in the past is cured like this", but is true and effective Experimental data, clinical experimental results, professional scientific research and analysis. These materials can be provided by professional websites, books, and people, but not advertisements. So, for some cancer claims that are popular in the society, you should look up more information and consider whether you believe it or not.
