Prostate cancer can usually be treated with radiotherapy in the context of early radical treatment, progressive adjuvant treatment, and late palliative treatment. 1. Early radical treatment: In the early stage of prostate cancer, the tumor is confined in the envelope. Radical radiotherapy can be used to treat prostate cancer and can achieve good results. 2. Progressive adjuvant treatment: In progressive prostate cancer, the tumor has broken through the peritoneum but has not yet metastasized. In this case, radiotherapy can be chosen to be followed by other means of comprehensive treatment. 3. Advanced palliative treatment: in advanced stage, the tumor has invaded the surrounding neighboring organs and cannot be surgically removed, so radiotherapy can be used as palliative treatment to prevent the disease from progressing. If the patient’s prostate gland shows uncomfortable symptoms, he should go to the hospital as soon as possible for consultation and standardized treatment after clear diagnosis, so as to avoid adverse consequences.
