Regular use of low-dose baby aspirin a common pain reliever may reduce the risk of breast cancer in women a new research has found. For the study published in the journal Breast Cancer Research researchers analysed data from more than 57000 women who were part of California's Teacher's Study. The researchers saw an overall 16 per cent lower risk of breast cancer in women who reported using low-dose aspirin at least three times per week. The study found an interesting protective association between low-dose aspirin and breast cancer said lead author Christina Clarke from the Cancer Prevention Institute of California.
