1、 Will the body feel during radiotherapy?
Radiotherapy is the use of linear accelerators to emit x/ γ Radiation, through the "invisible knife" of radiation, small-scale high-dose irradiation can "cut" off the tumor. The patient has no wound and does not need anesthesia. Because of its "invisible and untouchable" characteristics, it is known as the "invisible scalpel". So the patient has no feeling during radiotherapy.
2、 Is radiotherapy effective?
Radiotherapy not only has a wide range of treatment, but also has a very obvious effect. Its contribution to tumor cure is second only to surgery. According to who statistics, 45% of malignant tumor patients can be cured, of which 22% are cured by surgery, 18% by radiotherapy and 5% by chemotherapy. Whether it is suitable for radiotherapy should be determined according to the type and stage of the tumor and the physical condition of the patient.
3、 Is radiotherapy a way to kill 1000 enemies and lose 800?
For the criticism of radiotherapy, people say most that radiotherapy will kill a large number of normal cells while killing cancer cells, so the therapeutic effect often outweighs the loss. This is probably one of the sources of people's prejudice against radiotherapy. With the rapid development of radiotherapy technology, the problem of "accidental injury" to normal cells has been well solved in the era of precision radiotherapy.
4、 How many times does radiotherapy need to be done?
The number of radiotherapy is determined according to the type and stage of the patient's tumor and the patient's own situation. Generally, patients do 20 to 30 times. If it is suitable for SBRT or SRS, it only needs to be done within 10 times.
5、 Are the side effects of radiotherapy comparable to chemotherapy?
We often see on TV that cancer patients will have serious side effects such as alopecia, nausea and vomiting after chemotherapy, while radiotherapy and chemotherapy are often compared because there is only a word difference. Many people think that radiotherapy will also have serious side effects. Although radiotherapy patients will also have some side effects, they are mainly local reactions. The side effects of radiotherapy are often related to the irradiation site, irradiation time and dose. As long as the symptoms are treated in time, there will be no sequelae.
6、 Is there any radiation in the radiotherapy department?
The key weapon for the radiotherapy department is the linear accelerator, which generates high-energy electrons through high voltage to bombard the tungsten target, thereby generating high-energy X-rays and electron lines. X-ray and electronic lines are generated only when power is on, and disappear after power is off. Moreover, the protection of the machine room of the radiotherapy department is safe and effective, and there is no radiation outside the machine room.
7、 Is there radiation on patients undergoing radiotherapy?
Some patients dare not hold their children when they return home after radiotherapy, feel that radiation on their bodies will affect their children, and dare not contact others. The X-ray or electron ray generated by the linear accelerator has no radiation source, no radiation, no radiation on the patient, no residual in the body, no secondary radiation.
8、 What is the difference between radiology and radiotherapy?
There is a word difference between radiology department and radiotherapy department. Radiology department is a medical technology department used for disease diagnosis, such as CT, X-ray and other examinations. Radiotherapy department is a clinical department that uses radiation to treat tumors. Patients should choose tumor radiotherapy clinic when registering.
9、 Can I stop during radiotherapy?
It can't be stopped under normal circumstances. The treatment mode of radiotherapy is formulated repeatedly and accurately. If the radiotherapy is stopped for a few days in the middle, it will affect the treatment effect. If the patient's response to radiotherapy is obvious or other complications must be stopped, the time should not exceed one week.
10、 Does radiotherapy need contraindications?
Radiotherapy patients should choose a light, digestible and nutritious diet to ensure various nutritional needs during treatment, but special attention should be paid to some tumors, such as digestive tract tumors or tumors that may damage the digestive tract during treatment. Attention should be paid to reducing the burden of the digestive tract and avoiding the damage of dry and hard food.
