Groundbreaking DNA tests could spot men most likely to fall victim to under-the-radar prostate cancer [Video]

SCIENTISTS are developing a DNA test to tell if a man’s prostate cancer will come back.

Patients who are at genetic risk of tumour cells flying under the radar and surviving radiotherapy could get extra treatment to make sure they are all wiped out.

Current scans often cannot see the cells as they hide in tiny glands – but a man’s genes could give them away.

Dr Jane Shortall, of the University of Manchester, said: “We’ve found that a man’s DNA can affect the likelihood of whether his cancer will spread to where it can evade radiotherapy.

“Armed with this knowledge, we’re working out for the first time how to identify these men so we can adjust their treatment.

“We’re also looking at how to spot the early signs of cancer returning in follow-up scans …
