New blood test can identify prostate cancer patients most suited to a 'riskier' course of treatment, research suggests

How many people does it kill? 

More than 11,800 men a year – or one every 45 minutes – are killed by the disease in Britain, compared with about 11,400 women dying of breast cancer.

It means prostate cancer is behind only lung and bowel in terms of how many people it kills in Britain. 

In the US, the disease kills 26,000 men each year.

Despite this, it receives less than half the research funding of breast cancer and treatments for the disease are trailing at least a decade behind.

How many men are diagnosed annually?

Every year, upwards of 52,300 men are diagnosed with prostate cancer in the UK – more than 140 every day.   

How quickly does it develop? 

Prostate cancer usually develops slowly, so there may be no signs someone has it for many years, according to the NHS. 

If the cancer is at an early stage and not causing symptoms, a policy of ‘watchful waiting’ or ‘active surveillance’ may be adopted. 

Some patients can be cured if the disease is treated in the early stages.

But if it is diagnosed at a later stage, when it has spread, then it becomes terminal and treatment revolves around relieving symptoms.

Thousands of men are put off seeking a diagnosis because of the known side effects from treatment, including erectile dysfunction.

Tests and treatment

Tests for prostate cancer are haphazard, with accurate tools only just beginning to emerge. 

There is no national prostate screening programme as for years the tests have been too inaccurate.

Doctors struggle to distinguish between aggressive and less serious tumours, making it hard to decide on treatment.

Men over 50 are eligible for a ‘PSA’ blood test which gives doctors a rough idea of whether a patient is at risk.

But it is unreliable. Patients who get a positive result are usually given a biopsy which is also not fool-proof. 

Scientists are unsure as to what causes prostate cancer, but age, obesity and a lack of exercise are known risks.
