Exams and Tests
Tests if you have symptoms
If you are having problems urinating, your doctor may use tests to see if you have an enlarged prostate (Reference benign prostatic hyperplasia Opens New Window). This condition is the most common cause of urination problems.
- A Reference digital rectal exam, in which the doctor inserts a gloved finger into your rectum to feel your prostate gland. Some prostate tumors can be found this way.
- A Reference PSA test to measure the levels of prostate-specific antigen (PSA) in your blood. A higher level of PSA may be a sign of an enlargement, infection, or cancer of the prostate. If it's possible that an infection is raising your PSA, you may first have 4 to 6 weeks of Reference antibiotics Opens New Window. Your doctor may suggest a second PSA test before thinking about doing a biopsy.
- A Reference transrectal ultrasound Opens New Window, in which the doctor inserts a probe into your rectum to check your prostate. The probe uses sound waves (ultrasound) to create a picture of the prostate.
If tests point to prostate cancer, your doctor may recommend a Reference prostate biopsy, in which tissue is taken from the prostate and examined under a microscope. A biopsy is the only way to confirm whether you have prostate cancer.
Tests after diagnosis
After prostate cancer has been diagnosed, tests will be done to see if Reference the cancer has spread Opens New Window. Tests include:
Tests after treatment
After treatment for prostate cancer, you have regular checkups to check for any signs that the cancer has come back or spread. Tests include:
- Blood tests. Different types of blood tests are used to see whether cancer has spread to your bones or liver.
- A bone scan to check for bone damage caused by the cancer spreading.
- A CT scan or MRI to look for a new tumor.
Screening for prostate cancer involves checking for signs of the disease when there are no symptoms. It may be done with the digital rectal exam and the PSA test. And while it's important to have regular health checkups, experts disagree on whether PSA testing should be used to routinely screen men for prostate cancer. Testing could lead you to have cancer treatments that you don't need.
So talk with your doctor. Ask about your risk for prostate cancer, and discuss the pros and cons of PSA testing.
