Radiotherapy, together with surgery and chemotherapy, constitute the three basic treatments for tumors. Compared with other conventional treatments, radiotherapy has the following advantages: 1. Radiotherapy has a wide range of application and can be used for tumors in almost all parts of the body. 2.
2. It does not have high requirements on patients’ conditions: many patients who are old, have poor physical condition, or have undergone multiple surgeries in the past can still receive radiotherapy.
3.Effective and reliable, can be applied alone or in combination with surgery and chemotherapy.
4.The treatment process is simple and less painful, and hospitalization is not necessary, which is easily accepted by patients.
5.The side effects of treatment are relatively small and can avoid anesthesia accidents caused by surgery, blood transfusion reactions, postoperative infections or side effects such as hair loss and vomiting caused by chemotherapy.
6.It is non-invasive treatment, and simple radical radiotherapy for early tumors can preserve the physiological functions of organs while eliminating tumors.
7. Pre-operative radiotherapy can improve the resection rate of surgery without affecting the operation, and improve the preservation rate of organs without affecting the efficacy; post-operative radiotherapy can reduce the local recurrence rate and improve the survival rate.
