Prostate biopsy

Overview

A prostate biopsy is a procedure where a doctor takes tiny samples of tissue from the prostate gland. These samples are checked for cancer or other problems.

Yes, prostate biopsies are common – thousands are performed each year in the UK and around the world.

It affects men, mostly over age 50, or younger men with a high risk of prostate problems.

Symptoms

Common symptoms

• A high PSA level found during a routine blood test
• An abnormal feeling during a digital rectal exam (when the doctor checks the prostate with a gloved finger)

Symptoms in children

• Prostate biopsy is not performed in children.

Symptoms in older adults

• Older adults may have a slightly higher risk of bleeding or infection after the biopsy.

Causes

Main causes

• An abnormal digital rectal exam (the doctor feels a lump or hard area)
• A rising or very high PSA level in blood tests
• A previous biopsy that showed abnormal but not cancerous cells

Risk factors

• Being older – most common after age 50
• Having a family history of prostate cancer (father or brother)
• Being of African-Caribbean or African descent (higher risk of aggressive disease)

When to see a doctor

See a doctor urgently if:

• If you have severe pain, fever, or cannot urinate after a biopsy – seek immediate care.
• If you notice bright red blood in urine for more than a day after the biopsy.

Book a routine appointment if:

• If you are over 50 and have never had a prostate check
• If you have a family history of prostate cancer and are over 45
• If you have urinary symptoms like trouble starting or stopping urination

Diagnosis

A prostate biopsy is the main test to check for prostate cancer. It is done after other tests suggest there might be a problem.

Tests that may be done

• PSA blood test (measures a protein made by the prostate)
• Digital rectal exam (the doctor feels the prostate through the rectum)
• MRI scan (magnetic imaging) – sometimes done before biopsy to guide the needle

What to expect at your appointment

You will lie on your side with knees bent. The doctor numbs the area with a local anaesthetic. A thin needle is inserted into the prostate through the rectum (or through the skin) to take several tiny samples. You may feel a quick pinch or pressure. The whole procedure takes about 10–15 minutes. Afterwards you can go home the same day.

Treatment

Treatment depends on what the biopsy shows. If no cancer is found, no further treatment is needed for the biopsy itself. If cancer is found, your doctor will discuss options based on the type, stage, and your overall health.

Self-care at home

• Rest for the rest of the day after the biopsy.
• Drink plenty of water to help flush your system.
• Avoid heavy lifting, vigorous exercise, and sexual activity for 2–3 days.
• Use a warm bath or a mild pain reliever (ask your doctor or pharmacist) for discomfort.

Medical treatments

If cancer is found, treatment may include active surveillance (monitoring without active treatment), surgery to remove the prostate, radiation therapy (using high-energy rays), or hormone therapy to reduce testosterone levels. Your cancer care team will explain what is best for your situation.

When is surgery considered?

If the biopsy shows a type and stage of cancer that is likely to grow, surgery (called a prostatectomy) to remove the prostate gland may be an option. This decision is made with your doctor based on your age, health, and personal preferences.

Living with this condition

After a biopsy, most men return to normal activities within a day or two. You may see a little blood in your urine or semen for up to a week – this is normal. If you have any concerning symptoms, contact your doctor.

Lifestyle tips

• Stay well hydrated to help any bleeding settle quickly.
• Avoid heavy lifting and strenuous exercise for a few days.
• Wear loose, comfortable clothing if you feel any soreness.

Diet and exercise

Eat as you normally would. Gentle walking is fine. Avoid vigorous activity for 2–3 days. A balanced diet rich in fruits and vegetables supports overall health.

Mental health and emotional wellbeing

Waiting for biopsy results can be stressful. It is normal to feel anxious or worried. Talk to your partner, a friend, or a counsellor about your feelings. Your doctor can also recommend support services.

Prevention

You cannot prevent needing a biopsy if tests suggest a problem. However, regular check-ups and being aware of your risk can help catch issues early. A healthy lifestyle may lower your risk of prostate cancer, but it does not guarantee you will never need a biopsy.

Screening programmes

There is no routine national screening programme for prostate cancer in the UK like there is for breast or bowel cancer. Men over 50 can ask their GP for a PSA test. If you are at higher risk (e.g., family history or African descent), you can talk to your doctor about starting earlier.

Complications

If left untreated

• If a biopsy finds cancer and it is not treated, the cancer may grow and spread.
• Infection or bleeding after the biopsy (rare but possible).
• Difficulty urinating or blood in urine for more than a week.

Long-term outlook

The outlook is very good. Most men who have a prostate biopsy do not have cancer, and even if cancer is found, treatment is very effective – especially when caught early. Modern treatments have fewer side effects than in the past, and many men live full, healthy lives after treatment.
