Diet and lifestyle
A Prostate Specific Antigen (PSA) test measures the amount of prostate-specific antigen in the blood. PSA is released into a man's blood by his prostate gland. Healthy men have low amounts of PSA in the blood. The amount of PSA in the blood normally increases as a man's prostate enlarges with age. PSA may increase because of inflammation of the prostate gland, known as Prostatitis or Prostate Cancer. An injury, a digital rectal exam, or sexual activity (ejaculation) may also briefly raise PSA levels.
Why PSA Test is done?
The Prostate Specific Antigen (PSA) test is done to :
● screen men for prostate cancer. Since other common medical conditions, such as Benign Prostatic Hyperplasia (BPH) and Prostatitis, can cause high PSA levels, a prostate biopsy may be done if your doctor is concerned about signs of prostate cancer.
● Check if cancer may be present when results from other tests, such as a digital rectal exam, are not normal. A PSA test does not diagnose cancer, but it can be used along with other tests to determine if cancer is present.
● Watch prostate cancer during active surveillance or other treatment. If PSA levels increase, the cancer may be growing or spreading. PSA is usually not present in a man who has had his prostate gland removed. A PSA level that rises after prostate removal may mean the cancer has returned or has spread.
How to prepare for PSA Test?
Before you have a Prostate-Specific Antigen (PSA), tell your doctor if you have had
● Test to look at your bladder Cystoscopy in the past several weeks.
● Prostate needle biopsy or prostate surgery in the past several weeks.
● Digital Rectal Examination in the past several weeks.
● Prostate infection (Prostatitis) or an Urinary Tract Infection (UTI) that has not gone away.
● Tube (catheter) inserted into your bladder recently to drain urine.
Do not ejaculate for 24 hours before your PSA blood test, either during sex or masturbation.
You must consult your doctor about any concerns you have regarding the need for the test, its risks, how it will be done, or what the results will mean.
