Prostate Cancer Warning Signs You Need To Know About

What a prostate check can involve

Getting checked for possible prostate cancer does not mean there is one definitive test performed at the first appointment. Assessment can involve several stages, depending on your symptoms, risk and initial results.

Your healthcare professional may begin by asking about urinary changes, sexual function, other symptoms, medications and family history. In some healthcare systems, they may also offer or discuss a physical examination of the prostate.

PSA blood testing

One common part of an assessment is a PSA blood test. PSA is produced by prostate cells, and the test measures its concentration in the blood.

An elevated result does not automatically mean prostate cancer. According to the US National Cancer Institute, benign prostate enlargement and inflammation or infection of the prostate can also increase PSA.

This is why PSA testing is generally considered part of a wider assessment rather than a simple positive-or-negative cancer test.

Further investigation

If initial findings suggest further investigation is appropriate, additional tests can be offered.

In England, the NHS prostate cancer testing guide says people referred to a specialist because prostate cancer is suspected will have an MRI scan. A specialist may subsequently recommend a biopsy, in which tissue samples are taken from the prostate and examined for cancer cells.

Depending on the circumstances, additional imaging can also be used after diagnosis to assess the disease.

What screening does — and does not — include

Screening is testing someone who does not have symptoms. Diagnostic investigation is testing prompted by symptoms or other concerning findings. The distinction matters because countries have different policies for routine screening.

The US CDC identifies PSA as the main prostate cancer screening test and explains that some clinicians may also use a digital rectal examination.

What is included, whether you need a referral and whether there is a charge will depend on your healthcare system, insurance arrangements and clinical circumstances. Check your national health service or insurer before assuming a particular test is automatically covered.

Who should consider speaking to a doctor?

There is no worldwide eligibility rule for prostate cancer screening. Recommendations vary by country, age, personal risk and whether you already have symptoms.

Anyone with a prostate who develops concerning symptoms should seek medical advice rather than relying on screening eligibility rules. Screening refers to testing people without symptoms; investigating symptoms is a different process.

Possible signs of prostate cancer include changes in urination, blood in urine or semen, erectile difficulties and, in more advanced disease, symptoms such as persistent back pain or unexplained weight loss. These symptoms have many possible causes.

Factors that can increase risk

According to the NHS information on prostate cancer risk, risk increases with age and is higher in some groups. Factors to tell your healthcare professional about include:

Increasing age
A family history of prostate cancer
Black African or African Caribbean background
Certain inherited genetic changes, including BRCA2
A close family history of some breast, ovarian or pancreatic cancers, which can sometimes indicate inherited genetic risk

Having a risk factor does not mean you have or will develop prostate cancer.

Screening eligibility differs internationally

In the United States, the CDC prostate cancer screening guidance reports the US Preventive Services Task Force recommendation that men aged 55–69 make an individual decision about PSA screening after discussing potential benefits and harms with a clinician. Routine PSA screening is not recommended by that body for men aged 70 and older.

The UK does not operate a national population screening programme that automatically invites all men for prostate cancer screening. The NHS PSA guidance explains when and why PSA testing may be considered.

Australia also does not treat PSA testing as a universal population-screening programme. The Australian Government's prostate cancer screening information advises people considering testing to discuss its potential benefits and harms with their doctor.

Rules and clinical guidance can change, so use your country's current health authority guidance rather than assuming another country's age thresholds apply to you.

Start with official healthcare services

If you are looking for reliable information about prostate cancer warning signs or testing, begin with your country's public health service, cancer agency or primary-care system rather than a commercial testing advertisement.

For people experiencing symptoms, a family doctor, GP or primary-care clinic is usually an appropriate first contact. Explain that you are concerned about possible prostate symptoms so the service can direct you appropriately.

United Kingdom

The NHS prostate cancer service information covers symptoms, risk factors, PSA testing, diagnosis and treatment.

If you have concerning symptoms or are worried about your risk, contact your GP. Depending on the assessment, the GP may discuss PSA testing, examination or referral for specialist investigation.

United States

The CDC prostate cancer screening information explains PSA screening and the importance of discussing its potential benefits and harms with a doctor.

People with health insurance should also check their plan's rules because coverage for screening and diagnostic investigations can differ.

The National Cancer Institute provides detailed information about screening, potential benefits, false-positive and false-negative results, overdiagnosis and follow-up investigations.

Australia and Canada

Australians can consult the Australian Government Department of Health for national information about PSA testing and prostate cancer screening.

Canada has historically not recommended PSA testing as a population-wide screening programme. Public-health guidance and preventive-care arrangements can change, however, and healthcare delivery varies by province and territory. The Public Health Agency of Canada provides information on Canadian preventive-health guidance.

Other countries

If you live elsewhere, look for:

Your national ministry or department of health
A government-funded health service
Your family doctor or primary-care clinic
Your national cancer agency
Your health insurer, where applicable

Avoid assuming that another country's screening age, referral process or funding rules apply where you live. If you already have symptoms, seek clinical advice rather than waiting until you qualify for a routine screening programme.

Know what to look for

The first thing to understand about signs of prostate cancer is that early prostate cancer may cause no symptoms at all. The NHS explains that symptoms often do not develop until the cancer has grown enough to affect surrounding structures or has spread.

Changes worth discussing with a healthcare professional can include:

Difficulty starting to urinate or needing to strain
A weak urine flow
A flow that repeatedly stops and starts
Needing to urinate urgently or frequently
Getting up during the night to urinate
Feeling that your bladder has not fully emptied
Blood in urine or semen
Difficulty getting or maintaining an erection
Unexplained weight loss or persistent lower-back pain

These symptoms are not proof of cancer. Benign prostate enlargement and other conditions can cause similar problems.

Check your personal risk

Before discussing screening, consider your age and family history. Tell your doctor if close relatives have had prostate cancer or if your family has a history of breast, ovarian or pancreatic cancer, because inherited genetic changes can sometimes affect prostate cancer risk.

Your ethnic background can also be relevant. The NHS identifies Black African and African Caribbean background as associated with increased prostate cancer risk.

Understand PSA before having the test

A PSA result is not a cancer diagnosis. PSA can be elevated because of prostate cancer, but also because of conditions such as benign prostate enlargement or prostatitis.

The National Cancer Institute explains that PSA screening can produce false-positive results and can lead to further investigations. Screening can also identify cancers that might never have caused health problems during a person's lifetime.

Check local guidance

Before arranging routine screening, check the current recommendations in your country and discuss your individual circumstances with a healthcare professional. Screening approaches differ between the UK, US, Australia, Canada and other countries.

Most importantly, do not dismiss new, persistent or worsening symptoms simply because they are common or because you are outside a routine screening age range. Symptoms require an individual medical assessment rather than a screening eligibility check.

How to get checked

There is not usually an application for a single universal prostate cancer test. The first step is normally to contact a primary-care doctor, GP, clinic or other appropriate healthcare professional and explain whether you have symptoms, are concerned about your risk, or want to discuss screening.

Be specific about any changes you have noticed, including when they began and whether they are becoming more frequent or severe. Possible symptoms include difficulty starting urination, a weak or interrupted urine flow, needing to urinate more often or urgently, blood in urine or semen, erectile difficulties and, particularly with advanced disease, unexplained weight loss or back pain.

The NHS prostate cancer symptoms guide stresses that these symptoms can also be caused by non-cancerous conditions such as an enlarged prostate.

What happens next?

Depending on your country, symptoms and risk factors, your healthcare professional may discuss:

Your symptoms and medical history
Prostate cancer in your family
A prostate-specific antigen (PSA) blood test
A physical examination
Referral to a urologist or specialist
Further investigation if an initial test is abnormal

A PSA test measures prostate-specific antigen in your blood. It cannot by itself confirm whether you have cancer because PSA can also rise for non-cancerous reasons. The US National Cancer Institute PSA guide explains these limitations.

Country-specific routes

In the UK, start with your GP. The NHS says you can discuss a PSA test even without symptoms, although whether testing is appropriate should be considered alongside your individual risk and the benefits and limitations of testing.

In the US, screening is generally a shared decision rather than an automatic test. The CDC screening guidance recommends discussing potential benefits and harms with your doctor.

Elsewhere, contact your national health service, family doctor or local healthcare provider because screening policies, referral procedures and costs vary. If you have symptoms rather than simply seeking routine screening, make that clear when requesting an appointment.
