At present, there is no authoritative data to show how long the endocrine treatment of advanced prostate cancer can live, and the general patients can live for about five years. Prostate cancer is a relatively slow-progressing cancer, and once prostate cancer begins to grow rapidly and spread outside the prostate, the condition is relatively serious. In advanced stages, patients may experience pain, numbness and swelling in the pelvis, lower back, ribs and other parts of the body, accompanied by weight loss and loss of appetite. Patients with advanced prostate cancer can usually live for about five years after endocrine treatment, and some patients have a better prognosis and survive longer, so it is impossible to generalize. However, if the patient develops cancer extension, his survival time will be relatively shorter. Patients are advised to follow the doctor’s instructions to have regular checkups in order to know how the disease is recovering. During the treatment period, patients with prostate cancer should maintain a positive and optimistic mindset, ensure sufficient rest time and do not overwork. Balanced diet, less spicy and stimulating food, and more fresh fruits and vegetables can be eaten to prolong life and improve the quality of life as much as possible.
