The prostate gland is only about the size of a walnut. It's below the bladder and around the urinary tube. Doctors have several ways to test for tumors. If you're 50 or older, talk to your doctor about your need for prostate cancer screening. Here are some things the doctor can check.
Doctors can check to see if they can feel the tumor during a rectal exam.
The doctor inserts a gloved finger into the rectum to feel the prostate. These are called PSA scores. A PSA of less than 4 nanograms per milliliter of blood is considered normal. In one-third of men, this score indicates early cancer. In more than half of these men with cancer, the tumors have already spread beyond the prostate.
