Types of Prostate Cancers

Prostate cancer is a cancer of the prostate that affects one in six men in the United States. It is one of the most common forms of cancer in men. There is one type of prostate cancer, which is classified into stages by the spread of the cancer.

Stage I

During stage I prostate cancer, the cancer is isolated to the prostate, is microscopic and can only be detected during a transurethral resection and less than 5 percent of the tissue is cancerous. The five-year survival rate for this stage is 100 percent.

Stage II

During stage II, prostate cancer is still located in the prostate but can be detected with a digital rectal exam, transrectal ultrasound or needle biopsy. Like stage I prostate cancer, the five-year survival rate for this stage is 100 percent.

Stage III

During stage III prostate cancer, the cancer has begun to spread outside of the prostate, but has not affected the lymph nodes. The five-year survival rate for this stage is 89 percent.

Stage IV

During stage IV prostate cancer, the cancer has spread into other areas of the body (referred to as metastasis). The five-year survival rate for this stage is 37 percent.

Treatment

Treatment for prostate cancer is stages I through III can be treated. However, doctors consider stage IV prostate cancer to be untreatable.
