The survival rate of prostate cancer is related to several factors, such as the period of detection of prostate cancer. If prostate cancer is detected at an early stage and aggressive treatment is taken, the 15-year survival rate is still relatively high. The current statistics are based on 1-year, 3-year and 5-year survival rates, and survival beyond 5 years is basically considered a cure. For prostate cancer, if it is detected early and treated aggressively with radical surgery or endocrine therapy, the 15-year survival rate should be around 20% or even higher. If prostate cancer is detected late, or if there are no longer conditions for surgery, or if local or distant metastases have developed, the survival rate will be significantly shorter, and the 5-year survival rate will be low, and the 15-year survival rate will be even lower, so it depends on the time of prostate cancer detection. It is also important to consider the pathological staging of prostate cancer. For prostate cancer with a high malignancy grading of the Gleason score, it has a relatively low survival rate. If the tumor is less malignant, that is, if the Gleason score is 6-7, the 15-year survival rate is much higher than that of patients with more malignant prostate cancer, so it still depends on the time of detection and the degree of malignancy of the pathology to determine the survival rate.
