Following his recent terminal cancer diagnosis, Olympic cyclist Sir Chris Hoy has called for more, younger men to be tested - including those with a family history of the disease - and the government has asked the NHS to examine the evidence again.Following his recent terminal cancer diagnosis, Olympic cyclist Sir Chris Hoy has called for more, younger men to be tested - including those with a family history of the disease - and the government has asked the NHS to examine the evidence again.
Oliver Kemp, head of the charity Prostate Cancer Research, said the current system is not working.
He told the BBC's Today Programme: "Not everyone is even aware that they have a prostate, never mind that they are at higher risk.
"Not as many people are turning up to their doctors as they should be."
More men dyingMore men dying
The debate around prostate screening revolves around an imperfect test and the trade-off between finding some men’s aggressive cancers earlier and the harms of diagnosing and treating slow-growing tumours that would never have affected a man’s health or lifespan.The debate around prostate screening revolves around an imperfect test and the trade-off between finding some men’s aggressive cancers earlier and the harms of diagnosing and treating slow-growing tumours that would never have affected a man’s health or lifespan.

The blood test men over 50 can request from their GP measures prostate-specific antigen (PSA), released by the prostate, a small gland located below the bladder involved in the production of semen.The blood test men over 50 can request from their GP measures prostate-specific antigen (PSA), released by the prostate, a small gland located below the bladder involved in the production of semen.
But PSA levels can be high for a variety of reasons - including an enlarged prostate, inflammation or infection, recent vigorous exercise or sex - or remain normal despite cancer.But PSA levels can be high for a variety of reasons - including an enlarged prostate, inflammation or infection, recent vigorous exercise or sex - or remain normal despite cancer.

Follow-up magnetic resonance imaging (MRI) scans and a tissue biopsy can help narrow down which men have cancer and need treatment - but some still end up being treated for something that would never cause a problem.Follow-up magnetic resonance imaging (MRI) scans and a tissue biopsy can help narrow down which men have cancer and need treatment - but some still end up being treated for something that would never cause a problem.
"Far more men have tests done to try to work out what kind of prostate cancer it is, than are going to benefit from it - there's the problem," Dr McCartney says."Far more men have tests done to try to work out what kind of prostate cancer it is, than are going to benefit from it - there's the problem," Dr McCartney says.
