Breast Cancer Risk Factors

 

According to the Susan G. Komen for the Cure website, research indicates that there are known factors for breast cancer.  At this time, researchers agree on more than 20 factors that increase breast cancer risk and several factors that lower risk. Some of these risk factors affect risk a great deal and others by only a small amount.

While there have been great advances in our knowledge, it’s still not understood what causes breast cancer to develop at a certain time in a certain person. It’s likely a combination of risk factors (many of which are still unknown) that together make cells in the breast turn cancerous. But exactly why a certain combination of factors might cause cancer in one person, but not in another is still unclear.

Although there are steps nearly everyone can take to lower risk, no one has full control over whether he/she gets breast cancer. Many risk factors are still unknown and many are simply out of our control (such as getting older or having a family history of breast cancer).

However, there is a lot that you can do to reduce your risk from breast cancer. Leading a healthy lifestyle can help lower risk (more) and getting regular screening tests can detect breast cancer early when it’s most treatable (more). Finally, having a general knowledge of what factors may increase your risk can help you work with your health care provider to address concerns he/she has and develop a breast health plan.
