Nowadays, many tumor patients and their families do not understand the principles and effects of radiotherapy and toxic side effects, and blindly believe in radiotherapy, which has caused a lot of regrets. Chemotherapy is a destructive treatment to the human body and can also be said to be a treatment with toxic effects on the human body, so clinicians ask patients to sign a chemotherapy consent form and also inform patients and their families of the possible consequences and reactions. Generally, most patients can tolerate chemotherapy in 1-3 times, but they cannot tolerate it after more times, and they may even die during the treatment due to chemotherapy (but the mortality rate is very low). After 6 times or more, patients may have recurrence and metastasis in the near future, and chemotherapy again may shorten the person’s life along with the pain. The same is true for radiotherapy, especially for patients with larger tumors and higher doses of radiotherapy, who are also prone to radiation damage from radiotherapy, increasing the patient’s suffering, such as pain, dry mouth, hair loss, anxiety, insomnia, etc. Generally, the life of patients with more radiotherapy and chemotherapy and larger doses will be shortened, and it is more difficult to relieve the pain and the disease, and the follow-up treatment is tricky, because excessive radiotherapy and chemotherapy destroy the normal physiological function of patients, the human body cannot repair itself, and the drugs are difficult to work. Therefore, do not blindly superstitiously believe in radiotherapy when suffering from tumor, but treat moderately and choose the correct and suitable treatment based on maintaining normal physiological function.
