There are several types of breast cancer. The type of cell affected in the breast determines the type of breast cancer. Carcinoma- Majority of breast cancers are carcinomas which arise from epithelial cells. When the epithelial cells are from glandular tissue involving milk ducts and glands, such type of carcinoma is called as adenocarcinoma.Sarcoma -Less common types of breast cancer include sarcomas which arise from cells of connective tissue of muscle, fat or blood vessels. Depending on the extent of spread of cancer into surrounding tissues cancer can be categorized into two types Invasive (Infiltrating) breast cancer-where the breast cancer invades into the surrounding breast tissue by breaking through the duct and lobular wall. Invasive cancer becomes metastatic once it spreads to lymph nodes or distant organs.Non-invasive (In situ) breast cancer- where the breast cancer does not spread to surrounding fatty and connective tissue and remains in a particular location(ducts, lobules) of the breast. Common types of breast cancer Invasive/Infiltrating ductal carcinoma (IDC) not otherwise specified (NOS) is the most common invasive cancer accounting to about 80% of all breast cancers. It originates in the milk ducts of breast tissue and invades into the surrounding fatty tissue through the wall
