What are the signs that prostate cancer has spread?

Prostate cancer can spread to the lymph nodes in the groin area, or to other parts of the body. The most common symptoms are swelling and pain around the area where the cancer has spread. Cancer cells can stop lymph fluid from draining away. This might lead to swelling in the legs due to fluid build up in that area.

At what PSA level should a biopsy be done?

A lower percent-free PSA means that your chance of having prostate cancer is higher and you should probably have a biopsy. Many doctors recommend a prostate biopsy for men whose percent-free PSA is 10% or less, and advise that men consider a biopsy if it is between 10% and 25%.

How painful is a biopsy of the prostate?
