prostate screening test preparation
Informed by recognized medical guidance
Overview
A prostate screening test checks the health of your prostate gland, which is a small gland in men that helps make semen. The most common screening is a blood test called a PSA test, which measures a protein made by the prostate. Some men also have a digital rectal exam (DRE), where a doctor feels the prostate through the rectum. This screening is not a diagnosis — it only suggests if more tests might be needed.
Key facts
- Prostate screening is a personal choice — talk with your doctor about whether it is right for you.
- A PSA blood test does not require any special preparation, but some things can affect the result.
- If your PSA level is high, it does not always mean cancer — infections, an enlarged prostate, or recent activity can raise it.
- Screening is most often offered to men over 50, or earlier if you have a family history of prostate cancer.
Prostate screening is a common test offered to men as part of routine health checks. Many men choose to have it, especially as they get older.
Prostate screening is for men, usually starting at age 50. It may be offered earlier to men with a family history of prostate cancer or who are of African-Caribbean or African-American descent, as they have a higher risk.
Symptoms
- If you cannot urinate at all (sudden inability to pass urine)
- If you have severe pain in your lower belly or back along with fever and chills
- If you see a lot of blood in your urine (or blood with clots)
- ⚠If you have burning pain when urinating, fever, or feeling very unwell — these could be signs of a prostate infection
- ⚠If you have new, severe back pain that does not go away
Common symptoms
- Most men having prostate screening do not have any symptoms — screening is done to check for problems early.
- If you have symptoms like trouble urinating, weak urine flow, or pain when urinating, your doctor may recommend screening to find the cause.
Symptoms in children
- Prostate screening is not relevant for children.
Symptoms in older adults
- Older adults (men over 70) may still discuss screening with their doctor, but the benefits may be smaller because prostate cancer can grow slowly and other health issues may be more important.
Causes
Main causes
- Prostate screening is not for a disease — it is a test to check for signs of possible prostate problems.
- A high PSA level can be caused by prostate cancer, an enlarged prostate (benign prostatic hyperplasia), prostatitis (infection or inflammation of the prostate), or recent activities like cycling or ejaculation.
Risk factors
- Age (over 50)
- Family history of prostate cancer (father or brother)
- Being of African-Caribbean or African-American descent
- Obesity
When to see a doctor
See a doctor urgently if:
- If you have any warning symptoms like sudden inability to urinate, severe pain, or fever with urinary issues — see a doctor the same day.
Book a routine appointment if:
- If you are a man between 50 and 70 and want to discuss prostate screening, make a routine appointment with your GP.
- If you are younger but have a family history of prostate cancer, ask your doctor about screening.
Diagnosis
Prostate screening is not a diagnosis — it is a first step. If your PSA level is higher than normal or your DRE feels unusual, your doctor may recommend further tests, such as an MRI scan or a biopsy, to find out if cancer is present.
Tests that may be done
- PSA blood test — a simple blood test that measures prostate-specific antigen. No special preparation is needed, but avoid ejaculation and vigorous exercise (like cycling) for 48 hours before the test, as those can raise PSA.
- Digital rectal exam (DRE) — the doctor inserts a gloved, lubricated finger into the rectum to feel the prostate. It takes a few seconds and may be a little uncomfortable but not painful.
- If results are concerning: MRI scan of the prostate, then a biopsy (small samples of tissue taken with a needle) to check for cancer cells.
What to expect at your appointment
For the PSA test, you will have blood drawn from your arm — it is quick and similar to any other blood test. For a DRE, you will be asked to lie on your side with knees bent. The doctor will explain each step. The whole screening appointment usually takes 10–15 minutes. You can bring a list of questions.
Treatment
Treatment depends on what the screening finds. If the result is normal, no treatment is needed. If the result is high, your doctor will discuss next steps — which may include monitoring, more tests, or treatments. Treatment options for prostate problems range from active surveillance (watching closely) to medication, radiation, or surgery, depending on the diagnosis.
Self-care at home
- Before screening: avoid ejaculation and heavy exercise (like biking) for 48 hours before your blood test.
- After screening, if your result is normal, no self-care is needed.
- If you have an enlarged prostate, your doctor may suggest lifestyle changes like drinking less caffeine or alcohol in the evening to help with urination.
Medical treatments
If a prostate condition is found, your doctor may recommend treatments such as medicines to help with urination (like alpha-blockers or 5-alpha reductase inhibitors) or antibiotics if there is an infection. For prostate cancer, options may include active surveillance (regular monitoring), surgery to remove the prostate, radiation therapy, or hormone therapy. Your doctor will explain the benefits and risks of each option based on your specific situation.
When is surgery considered?
Surgery might be considered for prostate cancer that is likely to grow or spread, or for severe benign prostatic hyperplasia (enlarged prostate) that does not improve with medication. Surgery is not always needed — many men with low-risk prostate cancer choose active surveillance.
Living with this condition
If you are having prostate screening, most days are normal. If you are waiting for results or have a diagnosis, staying active and talking with your doctor can help you feel in control. Follow any preparation instructions before your test.
Lifestyle tips
- Stay physically active — moderate exercise like walking or swimming supports overall health.
- Limit alcohol and caffeine if they affect your urination.
- Avoid long periods of sitting on hard surfaces (like bike seats) for 48 hours before a PSA test.
- If you smoke, try to quit — smoking is linked to many health problems.
Diet and exercise
A balanced diet with plenty of fruits, vegetables, and whole grains may support prostate health. Some studies suggest that a diet low in red meat and high in tomatoes (cooked) and cruciferous vegetables (like broccoli) may be helpful, but no diet can prevent or cure prostate cancer. Regular exercise helps maintain a healthy weight.
Mental health and emotional wellbeing
Waiting for screening results or a diagnosis can cause anxiety. It is normal to feel worried. Talk to your partner, family, or a friend. If you feel overwhelmed, speak with your doctor or a counsellor. Men sometimes feel embarrassed about prostate exams, but remember that doctors do them every day — your comfort is important.
Prevention
Prostate cancer cannot be prevented, but a healthy lifestyle may lower your risk. Eating well, staying active, and maintaining a healthy weight are good for your overall health.
Vaccines
There are no vaccines to prevent prostate cancer.
Screening programmes
Screening itself is not prevention — it is a way to find potential problems early. Talk to your doctor about whether screening is right for you based on your age, risk factors, and personal values.
Complications
If left untreated
- Prostate screening is a test, not a treatment. Not having the test does not cause complications — but if you have symptoms and avoid seeing a doctor, a condition like prostate infection or advanced prostate cancer could lead to pain, difficulty urinating, or spread of cancer.
Long-term outlook
Most men who have prostate screening will receive normal results. Even if your PSA is high, it does not mean you have cancer. Many men with high PSA levels are simply monitored and never need treatment. For those who do have prostate cancer, the outlook is generally very good — especially if it is caught early. Treatment has improved greatly, and many men live full lives after a prostate cancer diagnosis.
