How long to take injections for prostate cancer needs to be judged according to the treatment effect, the patient’s physical condition and the development of the disease, and cannot be generalized. Prostate cancer is a malignant tumor that occurs in the prostate gland. Depending on the condition, some patients need to take androgen blocking therapy, including injections and medication. Injections use luteinizing hormone-releasing hormone analogs such as goserelin and leuprolide, which are injected every 28 days, and the duration of injection needs to be decided according to the condition. During the course of treatment, if hormone resistance occurs requiring other treatments such as radiotherapy, regular follow-ups are required to test prostate-specific antigen levels, and the exact treatment cycle is difficult to determine. If you are diagnosed with prostate cancer, you need to follow the doctor’s instructions, review on time and actively cooperate with the treatment.
