Your doctor will ask you about your symptoms and past health. A physical exam will be done which will include a brief exam of the prostate. This is done with a digital rectal exam (DRE). The doctor inserts a lubricated, gloved finger into the rectum. The prostate can be felt through the wall of the rectum.

More tests may be needed if the prostate feels abnormal or you have certain symptoms. The tests will show if cancer is present. Tests may include:
A biopsy may be done if early tests suggest prostate cancer. A biopsy is the removal of cells for testing. The tests will show if cancer cells are present.
A biopsy may show abnormal changes in prostate cells. These cells are not cancer. They don't cause symptoms, or need to be treated. However they do raise the risk that prostate cancer may grow. Men with HGPIN are watched for any changes. Another biopsy may be needed to test different parts of the prostate.
If prostate cancer is found, results from finished tests and new tests will help find out what stage it's in. The stage is based on how the tumor looks like during testing. It will help your doctors come up with ways to treat it. The stage of cancer is based on where the tumor is and how far it’s spread.
Once cancer is found, the next step is to determine how aggressive the cancer is. This is called grade of the cancer cells. A sample of cancer cells will be looked at by a specialist. A higher grade means the cancer is more aggressive cancer. This also means it is more likely to spread quickly.
The most common scale used is called a Gleason score. Gleason scoring combines two numbers and can range from 2 (nonaggressive cancer) to 10 (very aggressive cancer). Most Gleason scores used to assess prostate biopsy samples range from 6 to 10. A score of 6 is a low-grade prostate cancer. A score of 7 is a medium-grade prostate cancer. Scores from 8 to 10 is a high-grade cancer.
Genomic testing is also being used. It looks at genes to better understand risk of a cancer.
Tests that may help with cancer stage are:
Prostate cancer is staged from 1 to 4:
