Each has unique characteristics based on its location and course of growth. Below is a review of breast anatomy along with cancer type desciptions. Variations of breast cancer influence the treatment selected and the overall prognosis. Each breast has 15-20 sections called lobes. These, in turn, have many smaller sections called lobules.
Breast milk is produced in the lobes and is carried to the nipple via thin tubes called ducts.
Cancer can form in any of these breast structures. The most common type of breast cancer, ductal cancer, is found in the cells of the ducts. Lobular Carcinoma Cancer that begins in the lobes or lobules is called lobular carcinoma. Lobular carcinoma is more often found in both breasts than other types of cancer. Inflammatory Breast Cancer Inflammatory breast cancer is an uncommon type of breast cancer.
