German cancer research scientists explain that upwards of 30 percent of breast cancer cases can be completely prevented if a woman takes the necessary precautions.
Researchers explain that nearly 60,000 women are diagnosed with breast cancer each year in Germany. The goal of the study was to determine whether or not certain activities or behaviors may decrease this risk.
The study found the largest cause of breast cancer to be due to post-menopausal hormone replacement therapy (HRT). Nearly 20 percent of women from the study with breast cancer were in that group. An additional 13 percent of cases were caused by the lack of exercise. While there was some overlap in the groups, combining the two results in a nearly 30 percent of all breast cancer cases.
Two common risk factors for cancer and disease, obesity and alcohol consumption, were also analyzed. However, the results showed more cancer cases due to hormone therapy and lack of exercise than anything else.
Researchers explain the two largest factors of breast cancer are entirely in the hands of women. Exercising regularly increases health in so many different areas, not just breast cancer risk reduction.
Additionally, hormone replacement therapy is not recommended unless it is completely necessary.
