How does breast cancer start?

Breast cancer is cancer that begins in the breast tissue and occurs when cells in the breast change and grow out of control, according to Medline Plus, the US National Library of Medicine.

In addition, the Centers for Disease Control and Prevention (CDC) revealed that the most common types of breast cancer are:

  • Infiltrating ductal carcinoma. Cancer cells start in the ducts and then break out of the ducts and multiply in other breast tissues. These invading cancer cells can also spread, or metastasize, to other parts of the body.
  • Infiltrating lobular carcinoma. Cancer cells start in the lobules and then spread from the lobules to nearby breast tissues. These invading cancer cells can also spread to other parts of the body.

However, there are other, less common types of breast cancer, such as Paget’s disease, medullary breast cancer, mucinous breast cancer, and inflammatory breast cancer.
