Knowing the stage helps your doctor decide which treatment you need. You might have some of the following tests.
A bone scan shows up changes or abnormalities in the bones. Doctors usually scan your whole body to find out if cancer has spread into the bone.
X-rays use high energy rays to take pictures of the inside of your body. Doctors might use x-rays to help stage prostate cancer.
An MRI scan creates pictures using magnetism and radio waves. It can show where cancer is in the prostate gland and if it has spread.
CT scans take pictures of your body to find out where the cancer is and whether it has spread.
Ultrasound scans use high frequency soundwaves to create a picture of a part of the body. Doctors might use this test to see if your cancer has spread outside the prostate.
