According to a recent study published in the British Journal of Cancer,?type 2 diabetes may increase the risk of breast cancer for post-menopausal women. Although researchers believe the link may be indirectly associated with being overweight, they don?t rule out that type 2 diabetes may affect breast cancer risk directly.
There are several known risk factors for breast cancer. Certain lifestyle choices, including smoking, drinking, and an unhealthy diet, can increase the risk of breast cancer. These are factors that are linked to things a person does ? these can be changed. A person?s age, race, and family history, can also lead to increased risk of breast cancer ? these are inherited factors that cannot be changed.
In order to see if there was link between type 2 diabetes and breast cancer, the study examined 40 separate studies that had investigated the potential link between breast cancer and diabetes. Over?56,000 women with breast cancer were included in the studies. After reviewing all of the data, the researchers found that post-menopausal women with type 2 diabetes has a 27 percent increased risk of breast cancer. There were no links for pre-menopausal women or for women with type 1 diabetes.
Although the researchers are not certain of the underlying biological mechanism that could explain the link between type 2 diabetes and breast cancer, they do agree that the link could be direct from having type 2 diabetes or indirect from being overweight.
Being obese or overweight can also increase a woman?s chances of developing breast cancer. According to the American Cancer Society, being overweight or obese after menopause is linked to a higher risk of breast cancer, and data?from the UK Cancer Research Center suggest obesity raises the risk of post-menopausal breast cancer by up to 30 percent.
Several weight loss clinical trials from the National Institute of Health demonstrated that losing weight reduces a persons risk of developing chronic diseases, such as diabetes, as well as obesity ? which both increase the risk of breast cancers.?Metastatic breast cancer treatment NJ specialists agree that all women should engage in routine exercise to maintain a healthy weight.?Although some breast cancer risk factors are inherent, others can be prevented with changes in lifestyle choices.
