Treatment by stage Treatment of cancer of the prostate depends on the stage of the disease, and the patient's age and overall health. A doctor may choose to follow the patient's condition more closely rather than starting treatment immediately. This decision depends on whether the patient has symptoms of the disease, is elderly, has another more serious illness, or has only slightly abnormal tumor cells. Standard treatment may be considered because of its effectiveness in patients in past studies, or participation in a clinical trial may be considered.
