A ten-minute scanner could soon be offered to MEN in a supermarket car park to indicate if they are at risk of dying from prostate cancer.
Experts say that guys may only need one scan between ages 55 and 60 and will have peace of mind all their lives.

The groundbreaking exam would be the first time that a national prostate cancer screening program is offered on the NHS.
It was compared to a mammogram, offered to women every three years, aged 50 to 71, to detect signs of bad cancer. Some 450 men have already benefited from a life-saving MRI in a clinical trial, and another 350 are expected to be presented later this year.
If both trials succeed, researchers expect checks to be offered by mobile scanners in all major cities in England.
MOST IMPORTANT DEVELOPMENT IN 50 YEARS
Professor Mark Emberton, from University College London, said sweeps were the most important development in the diagnosis of prostate cancer in 50 years.
They must identify men with aggressive tumors that require treatment because they are more likely to spread and be life threatening.
Those with no signs of cancer or less aggressive tumors that never cause problems will be spared treatment.
Approximately 47,200 men are diagnosed with prostate cancer in the United Kingdom each year, of which 11,600 die from it.
Prof Emberton spoke about his upcoming trial and his hopes for a national screening program at the Cheltenham Science Festival.
He said: "Current trials are a world first and MRIs are the most important development in the diagnosis of prostate cancer in 50 years.
ONCE IN A LIFETIME TEST
"If we show that it works, we hope that decision makers will review the evidence and examine screening for all men aged 55 to 60 years.
"MRI machines are getting cheaper, faster and simpler, which means they will not have to be done in a hospital.
"It is quite possible that the MRIs are done in supermarket car parks and have one in every big city.
"We hope that 90% of men will have an irreproachable health check following a negative MRI.
"Men worry more and more about prostate cancer while celebrities share their stories.
"After Stephen Fry and others told their stories, many men went to hospital clinics to rebadure themselves.
"A negative MRI is the surest way to rebadure us." He added, "If it works, I think over time – and I do not see why it would not do it – maybe we have a test that we can offer the 55-year-old men, as a unique test in your life to see if you are at risk for prostate cancer.
Symptoms of prostate cancer
In most cases, prostate cancer has no symptoms until the growth is large enough to exert pressure on the urethra – the tube in which we pee.
Symptoms include:
- Need to urinate more often, especially at night
- Need to rush to the toilet
- Difficulty starting to pee
- Low flow
- To get tired and take a long time by peeing
- Feel that your bladder has not completely emptied
"And then, if you do, you are participating in a surveillance program." Professor Hashim Ahmed, who had led the previous trial at Imperial College London, said, "We wanted a test run. imaging similar to a mammogram that can be used in men.
"We are seeing similar rates of diagnosis and death in prostate and bad cancer, so it makes sense.
"In the future, we may be able to justify screening for prostate cancer in all healthy older men, as we do for women with bad cancer." Sophia Lowes, of
Cancer Research UK, said the charity currently did not support a prostate screening program because existing tests were not reliable enough.
But she added, "If there was good evidence that an MRI was an effective, acceptable and not too expensive screening tool, it could change our stance.
"We need to know if the men will attend and make sure it does not hurt, for example by reporting harmless cancers that are never likely to disturb someone in their lives."
Karen Stalbow, of Prostate Cancer UK, said: "This trial could be an exciting step forward for our ambition of a national screening program allowing men to obtain early diagnosis of prostate cancer allowing to save more lives.
"If the results are positive, then MRI could offer a first noninvasive stage of the diagnosis of prostate cancer in the future.

"All that offers men a simple and more effective way to get controlled for prostate cancer is a good thing and we look forward to seeing the results."
NHS England said: "The NHS England is already deploying some of the latest developments in MRI for the diagnosis and care of prostate cancer as part of our ambition to detect more cancers earlier and save lives.
"This new test is potentially an exciting development that the NHS will look at as more evidence becomes available."
