Types of Breast Cancer

The breast is made up of ducts and lobules surrounded by fatty tissue.

• Cancer confined within a duct is called ductal carcinoma in situ (DCIS). Lobular carcinoma in situ (LCIS) is cells confined to a lobule.

• Tumors that break through the wall of the duct or lobule are called infiltrating ductal or infiltrating lobular carcinomas.

• Inflammatory breast cancer may involve the entire breast with specific skin changes and swelling.
