In most cases, prostate cancer is very slow growing, and many, if not most, patients will live with the cancer until they eventually die of some other natural, unrelated cause. The majority of patients with localised (cancer which has not spread to other parts of the body) prostate cancer live for a long time after diagnosis: 85% of all prostate cancers are diagnosed before the cancer has spread to other parts of the body and the 5-year survival rate for patients who are diagnosed in these early stages of the disease is almost 100%.If you have been diagnosed with prostate cancer, your doctor will discuss your treatment options with you. These will depend on how the cancer has grown, your PSA levels, your age and general health status.
