Experts have developed a potentially “game-changing” test to predict a woman’s risk of breast cancer.
It combines information on family history and hundreds of genetic markers with other factors, such as weight, to give the most comprehensive assessment possible, says Cancer Research UK.
The test is not yet routinely available on the NHS – some GPs and specialists are trialling it first.
It is part of a push to spot cancers earlier through tailored screening.
Women at high risk could be given preventative treatments or offered more checks, say the researchers.
Nearly 55,000 women are diagnosed with breast cancer each year. A large proportion of the cases occur in women who have risk factors.
