There are two ways that low dose aspirin can reduce the risk of breast cancer.
Lose dose or “baby” aspirin is only 81 mgs and works via two mechanisms for cutting the risk of breast cancer.
A report in Breast Cancer Research says that the 81 mg low dose aspirins had cut the risk of breast cancer in participants from the California’s Teacher’s Study.
The study was led by Leslie Bernstein, PhD, and found an overall 16 percent lower risk of breast cancer in the women who had reported taking baby aspirin at least three times a week.
How Low Dose Aspirin Lowers Breast Cancer Risk
There is a class of drugs called aromatase inhibitors. These are commonly prescribed to women who’ve had the type of breast cancer that’s fueled by estrogen.
Aromatase inhibitors inhibit the levels of circulating estrogen in the patient’s body.
Aspirin is a weak aromatase inhibitor – that is, not as potent as the AI class of drugs – but enough to have an effect on suppressing circulating estrogen.
“We thought that if aspirin can inhibit aromatase,” says Dr. Bernstein in her report, “it ought to reduce the likelihood that breast cancer would develop,” and could also, as she says, improve a breast cancer patient’s prognosis once they are taken off their AI drug (which is usually prescribed for 10 years).
A second way through which a baby aspirin lowers the risk of breast cancer is by reducing body-wide inflammation.
Breast cancer is more likely to develop in a person with systemic inflammation.
Body-wide (systemic) inflammation is reduced via exercise, a plant-based diet, restriction of processed foods, and – according to Dr. Bernstein’s research – low dose aspirin taken regularly.
And by the way, you may want to up your intake of white button mushrooms; they are nature’s aromatase inhibitors!
“…diets high in mushrooms may modulate the aromatase activity and function in chemoprevention in postmenopausal women by reducing in situ production of estrogen.” – Journal of Nutrition (Dec. 2001)
