Cause of DCIS

No one knows the cause of DCIS. The same factors that cause women to be at risk for developing invasive breast cancer may lead to the development of DCIS. Being at risk for breast cancer and DCIS is partially due to our genes. We cannot do much about our genetic nature, but we can do something about exercise and diet.

Women who consume a high-fat diet have a higher incidence of breast cancer. Exercise decreases a woman's risk of breast cancer. Alcohol consumption also increases breast cancer risk, along with postmenopausal weight gain. A healthy lifestyle with a low fat diet, adequate sleep, exercise and low stress is believed to reduce the incidence of DCIS and invasive breast cancer.
