A new prostate cancer Deoxy ribonucleic Acid (DNA)/genetic material test identifies the one in 100 men who are six times more at risk of developing the life-threatening disease.
Researchers identified 63 new genetic mutations that are linked to the condition, which they combined with more than 100 DNA variants that were already known to cause the condition, to create the test, which could cost as little as £30.
The findings were published in the journal Nature Genetics.
One per cent of men carry many of these risky genetic variations, putting them at a much higher risk of prostate cancer than the average male, a study found today.
These DNA mutations tend to occur in cells that regulate communication between the immune system and other parts of the body, which could pave the way for new treatments, according to the researchers.
The scientists, from The Institute of Cancer Research (ICR), London, are planning to assess whether investigating the DNA of men’s saliva samples, taken in GP practices, could identify at-risk men.
Such men are currently identified via a blood test that assesses their prostate specific antigen (PSA) levels, which rise when the cancer occurs. Yet, results can be skewed by vigorous exercise, urine infections and certain medications.
The researchers analysed the genetic codes of nearly 80,000 men with prostate cancer and more than 61,000 without the disease.
Results suggest each DNA mutation individually has a small effect on men’s prostate-cancer risk, however, the combined effect could be dramatic.
Those at the highest risk are 5.7 times more likely to develop the disease, while people in the top 10 per cent are 2.7 times more at-risk that the average man.
Meanwhile, a 52-year-old mother who took cannabis oil to battle her terminal cancer has been given the all-clear by doctors.
According to the report published by DailyMail UK Online, Joy Smith was told she would only have six weeks to live when she was diagnosed with incurable stomach and bowel cancer in August 2016.
In a desperate attempt to defy expectations, she began taking a cannabis oil that contained THC, which is illegal in the United Kingdom (UK). She is believed to have bought it online.
And after a rollercoaster two years, she found out on Monday morning that she was cancer-free and would no longer have to have chemotherapy.
Ms Smith, from Coventry, said: “I am going to party for the rest of my life. I have got to be the only person in the world who have survive this.
“I keep pinching myself to see if this is real. I am being monitored every three months, but other than that I have no more treatment planned.”
Ms Smith was told that she would have little longer than a month left to live unless she started chemotherapy to buy her more time.
