Prostate health: symptoms, PSA test and what to check

Men tend to see a doctor later than women, and urinary complaints are often put down to age for years. Yet frequent trips to the bathroom at night, a weak stream and a feeling that the bladder is not empty are symptoms that can be treated. The PSA blood test is a separate topic that causes a lot of confusion: it is useful, but it is not a simple yes-or-no test for cancer. Here is each in turn.

In short

  • Urinary symptoms such as waking at night to urinate, a weak or interrupted stream and a feeling that the bladder is not empty are common with an enlarged prostate, and they can be treated.
  • Benign prostatic hyperplasia (BPH) is noncancerous. The NHS says it is not caused by prostate cancer and does not raise your risk of it.
  • The PSA blood test measures a protein the prostate makes. A high level does not confirm cancer, and many other things can raise it.
  • For men aged 55 to 69, the US Preventive Services Task Force says to make their own decision about PSA screening after talking with a doctor about benefits and risks.
  • Being unable to urinate at all is an emergency.

Urinary symptoms

NIDDK lists the symptoms of an enlarged prostate as waking to urinate at night, a weak or interrupted stream, dribbling, trouble starting or emptying the bladder, urgency, frequency and pain on urinating. The NHS adds a feeling that the bladder is not fully empty. These symptoms usually develop slowly and may worsen with age, and NIDDK notes that how severe they are does not always match the size of the prostate.

MedlinePlus adds that symptoms can also come from prostatitis, an inflammation of the prostate that is the most common prostate problem in men under 50, and from prostate cancer. That is why new urinary symptoms deserve a proper assessment instead of a guess.

Enlargement versus cancer

NIDDK describes BPH as a noncancerous enlargement of the prostate, and its cause is unknown, though aging and hormone changes are suspected. The NHS says it is more common in men over 50 and in people with a family history, and that it does not raise the risk of prostate cancer.

MedlinePlus says prostate cancer is common in men 50 and older, that most cases grow slowly and may never cause harm, but that some are serious. The NHS stresses that urinary symptoms can sometimes signal more serious conditions, which is the reason to be checked rather than assume it is just BPH.

What the PSA test shows

The CDC explains that PSA is a substance the prostate makes, and that levels can be higher in men with prostate cancer. Non-cancerous conditions can also raise them. Age, race, certain procedures, certain medicines, an enlarged prostate and a prostate infection all affect the result.

A higher level makes a prostate problem more likely, but it does not confirm cancer. Because many factors play a role, the CDC says a doctor should interpret the result, and if it is abnormal the doctor may recommend a biopsy to find out whether cancer is present. This guide cannot interpret your own number. Ask your provider what it means for you.

Screening: a shared decision

The CDC says the US Preventive Services Task Force advises men aged 55 to 69 to make their own decision about PSA screening, after talking with a doctor about the benefits and risks of screening, and of other tests and treatments. The goal of screening is to find cancers that could spread if untreated, and to find them early.

The USPSTF recommendation covers men at average or increased risk, so talk to your provider about your personal risk, including family history. The CDC also says the Task Force does not recommend the digital rectal exam for screening because the evidence of benefit is lacking.

What you can do yourself

NIDDK and the NHS suggest these measures for urinary symptoms:

  • Limit fluids before going out or going to bed, but drink enough during the day. The NHS warns that cutting fluids too much can lead to problems such as urinary tract infections.
  • Cut down on alcohol and caffeine.
  • Stay active, eat enough fiber to avoid constipation and keep to a healthy weight.
  • Empty your bladder fully and do not hold urine for long periods. Wait a moment after urinating and try again, and relax instead of straining.
  • Ask a provider or pharmacist whether any of your other medicines could be worsening your symptoms. NIDDK names decongestants, antihistamines, tranquilizers, antidepressants and diuretics.

Treatment in general terms

NIDDK says mild symptoms that do not affect quality of life may need only watchful waiting, lifestyle changes and yearly checkups. For more troublesome symptoms it lists medicines such as alpha blockers, which relax the prostate and bladder neck muscles, and 5-alpha reductase inhibitors, which shrink or slow prostate growth. A combination can work better than either alone.

Minimally invasive procedures and surgery are options when medicines do not help, symptoms are severe or complications arise. Your provider will choose among them, and all medicines can cause side effects, so regular check-ups matter, as the NHS notes.

When to see a doctor and red flags

See your provider if you have difficulty urinating or need to urinate more often, since the NHS notes that doctors are used to discussing these symptoms. Get an urgent appointment for pain when urinating or blood in your urine. If you are 55 to 69, ask about the screening decision.

Red flags: the NIDDK says to seek care right away if you cannot urinate at all, have painful, frequent, urgent urination with fever and chills, see blood in your urine, or have severe lower belly pain. Call 911 or go to an emergency department.

Questions to bring:

  • What do my symptoms point to, and what tests do I need?
  • Should I have a PSA test, and what are the benefits and risks for me?
  • Could my medicines be contributing?
  • What are my options if lifestyle changes are not enough?

Questions and answers

Can an enlarged prostate turn into cancer?

No. NIDDK says BPH is not caused by cancer, and the NHS says it does not raise the risk of prostate cancer. The two can occur together, which is why new symptoms should still be checked.

Does a high PSA mean cancer?

No. The CDC says a high PSA makes a prostate problem more likely but does not confirm cancer, since an enlarged prostate, an infection, age and certain procedures can also raise it.

When should a man start seeing a urologist?

When you have symptoms that bother you, whatever your age. For screening with no symptoms, the USPSTF advises a shared decision for ages 55 to 69, so talk to your provider about your own risk.

Do prostate supplements help?

The health bodies cited here describe lifestyle measures and prescription medicines, and none recommends supplements. Ask your provider before taking any.

Should I drink less water at night?

Limiting fluids in the evening can reduce night-time trips, according to NIDDK and the NHS, but the NHS warns against cutting back too much overall.
