When 80-year-old patients suffer from prostate cancer, they need to be given surgical treatment, radiotherapy, chemotherapy and endocrine therapy as early as possible according to their specific conditions. 1. Surgery: it is the main treatment for prostate cancer, especially for early stage prostate cancer patients who need to be given radical prostatectomy as early as possible, including traditional prostatectomy, laparoscopic prostatectomy and so on. 2. Radiation therapy: the high energy of rays is applied to the cancer cells to kill them. 3. Chemotherapy: through the action of chemotherapeutic drugs, it can kill cancer cells, but it can also kill normal cells, so the side effects are relatively large, and the commonly used drugs include docetaxel. 4. Hormone therapy: because the development of prostate cancer is mostly related to androgen, so endocrine therapy can be taken, such as anti-androgen drugs like bicalutamide, and clinically it can also be treated by testicular resection or goserelin and other drugs for debulking. It is recommended to go to the hospital, improve the auxiliary examination to clarify the condition, and the drugs need to be used under the guidance of a professional physician.
