Breast Cancer

Scientists have long known about two specific mutations of genes that significantly increase a woman's risk of breast cancer, but these mutations are extremely rare. Now, two recent studies, one in Britain and one in the US, have identified four more genes that could indicate increased susceptibility to breast cancer. 'What we hope is that each of these genes will lead us to better understand the mechanisms and biology behind breast cancer,' said David Hunter, who was involved in both studies. Scientists hope this will enable them to identify more women who might be susceptible to the disease, as well as help them to devise treatments.
