Canadians Identify Biomarker for 80% of Breast Cancer Cases
Researchers have identified many genetic markers for familial breast cancers, but not for sporadic breast cancer, which accounts for 80 per cent of all cases. Sambasivarao Damaraju, a professor with the Faculty of Medicine & Dentistry and a researcher at the Cross Cancer Institute, worked with his team to scan the DNA of about 7,200 Alberta women, including those who have had sporadic breast cancer and those who have not had cancer. Their genomes were scanned from DNA isolated from blood.
The results? Women who had sporadic breast cancer frequently had a genetic marker on chromosome 4, a marker that has never been associated with familial breast cancer cases.
