Scientists from the German Cancer Research Center have completed a series of studies to highlight the avoidable risk factors for breast cancer, and which lifestyle choices may lead to the development of the disease, according to Sify.com
While most of the risk factors for breast cancer are well-known and documented, the researchers found that hormone replacement therapy and a lack of exercise increase a person's risk for breast cancer.
The study used a sample of 6.386 healthy women and 3,074 breast cancer patients and calculated the percentage of cases that could be tied directly to an avoidable breast cancer risk factors. The results found that close to 37 percent of post-menopausal breast cancers are linked to family history, age and other inevitable factors. The researchers concluded that nearly 30 percent of breast cancers could be prevented by changing detrimental habits.
"That means that two factors which each woman has in her own hands are responsible for a similar number of postmenopausal breast cancer cases as the non-modifiable factors," researcher Karen Steindorf told the news source.
According to BreastCancer.org, 1 in 8 women will develop some form of invasive breast cancer over the course of their lifetime.
