Scientists have identified a single rogue gene that serves to significantly boost the odds of a man developing breast cancer.
Through a number of recent studies, experts have observed that faulty genes are a key driver behind the development of breast cancer in women of all ages.
Now, a new paper released by researchers working at St Mary's Hospital in Manchester has singled out BRCA2 as a main cause of the disease in men, with their studies revealing that men who carry the faulty gene have a one in 15 chance of developing breast cancer before they reach the age of 70.
This compares with the one in 1,000 chance of the average male developing the condition over the course of their lifetime.
Writing up the findings in the Journal of Medical Genetics, lead researcher Prof Gareth Evans, said: "Men don't have to have a faulty copy of BRCA2 to get breast cancer, but the highest risk for men is if they have a faulty copy of the gene."
This comes as TV actress Jennifer Saunders has reportedly been given the 'all clear' after fighting against breast cancer for several years.
