lifestyle and environmental factors that may increase your risk of breast cancer. There are many risk factors that increase the chance of developing breast cancer. Although we know some of these risk factors, we don’t know the causes of breast cancer or how these factors cause the development of a cancer cell. It’s likely that breast cancer is caused by a complex interaction of your genetic makeup and your environment.

Breast cancer most often begins with cells in the milk-producing ducts (invasive ductal carcinoma). Breast cancer may also begin in the glandular tissue called lobules (invasive lobular carcinoma) or in other cells or tissue within the breast.

  • Genes: Women who have the BRCA1 and BRCA2 gene mutations are more likely to develop breast cancer than women who don’t. Other gene mutations may also affect your risk.
  • Gender: Being a woman is the main risk factor for breast cancer. Women are 100 times more likely to develop breast cancer than men.
  • Drinking alcohol: Drinking excessive amounts of alcohol raises your risk.
