What are the specific differences and advantages and disadvantages between chemotherapy and radiotherapy? Once a person has cancer, he must be treated in time. The most commonly used clinical treatments are surgery, radiotherapy and chemotherapy. Many people don't know the difference between radiotherapy and chemotherapy and their advantages and disadvantages. First of all, what we usually call chemotherapy is actually the abbreviation of chemotherapy, which is a method of treating diseases with chemically synthesized drugs. The advantages of chemotherapy are well known. No matter on TV programs or in life, as long as someone has cancer, they basically need chemotherapy.

This also shows that the therapeutic effect of chemotherapy is very good, although the effect of chemotherapy is very good and the side effects are great, but because chemical drugs can not distinguish between enemies and themselves when killing cancer cells, they will also cause damage to normal cells of the human body. Many drugs are used in chemotherapy. These drugs can kill cancer cells, many of which grow naturally. These drugs have different therapeutic effects on different patients.

There are also many people who use radiotherapy to treat tumors. Radiotherapy is also one of the three major cancer treatment methods. Radiation can inhibit and kill cancer cells. It can be used alone or in combination with surgery and chemotherapy, and the comprehensive treatment effect is better.

The advantage of radiotherapy is that it can reduce the size of the tumor. After radiotherapy, some patients who can't be operated can reach the surgical standard and get the chance of surgical cure. Patients with advanced cancer can also receive radiotherapy, which can relieve stress and pain. Although radiotherapy can bring good therapeutic effect, it will also bring side effects, such as fatigue, fatigue, sweating, drowsiness, etc., and the immunity will also decline.
