A study led by researchers based at the City of Hope hospital in California found that the use of low-dose aspirin (81 mg) reduces the risk of breast cancer in women who are part of the California’s Teacher’s Study.

The new study, released on 1 May 2017, which is the first to suggest that the reduction in risk occurs for low-dose aspirin, was proposed by City of Hope's Leslie Bernstein, Ph.D., professor and director of the Division of Biomarkers of Early Detection and Prevention, and published online in the journal, Breast Cancer Research.

The study saw an overall 16 percent lower risk of breast cancer in women who reported using low-dose aspirin at least three times per week. Such regular use of low-dose aspirin reduced the risk by 20 percent of estrogen or progesterone receptor positive, HER2 negative breast cancer, which is the most common breast cancer subtype.

Dr Richard Berks, Research Communications Manager, at Breast Cancer Now said:

“This new research adds to some previous studies that suggest a regular low-dose of aspirin may help prevent breast cancer. However, some other studies suggest there is little or no benefit of taking aspirin to prevent breast cancer. More research in this area is required and at this stage, we don’t recommend that women take aspirin regularly solely to lower their risk of breast cancer.

“Instead, we encourage all women to adopt a healthy lifestyle to reduce their risk of the disease, through regular physical activity, reducing their alcohol intake and maintaining a healthy weight.

“Like any drug, aspirin can have side-effects, so anyone considering taking aspirin on a regular basis should first speak to their GP, to discuss the potential risks and benefits.”
