What can affect my PSA level?
Prostate cancer is the is the most important cause for a raised PSA test but there are other reasons why it could go up for a short time too. These may affect how accurate the test result is.
One of the more common causes of an increased PSA, is an enlarged prostate. This is a condition called benign prostatic hyperplasia (BPH) and happens to most men as they get older.
You can read more about this condition by visiting the Prostate Cancer UK Site
There are other things that can affect your PSA level too, including if:
• you have a urine infection, or a recently treated urine infection
• you have had a recent prostate biopsy, surgery on your bladder or prostate, or a tube in your bladder to drain pee
You will be asked to wait at least 6 weeks before having the PSA test if any of these apply to you.
Other reasons for a raised PSA level include:
• recent ejaculation (within the last 48 hours)
• strenuous exercise, including cycling (you will be asked to stop for 48 hours before the test)
• receiving anal sex or having your prostate stimulated during sex (it would be worth avoiding this for a week before your PSA test)
• certain medicines including finasteride (Proscar®), dutasteride (Avodart®, Combodart®) (if you have a PSA test, always inform your health professional about any medicines you are taking)
