Disease/Condition Glossary

Breast cancer is a type of cancer that develops in breast cells stimulated by a female sex hormone called estrogen. Breast cancer may form in lobules (glands that produce milk), ducts of the breast (the pathway that brings milk from glands to the nipple), fatty tissue, or fibrous connective tissue within the breast. The tumour cells invade other healthy breast cells and travel to lymph nodes, a primary pathway for the cancer cells to move to other parts of the body. Symptoms of breast cancer include a lump in the breast or tissue thickening which feels different than the normal surrounding tissues, breast pain, redness, swelling, nipple discharge other than breast milk, bloody discharge, unexplained change in shape, size, or appearance of the breast, peeling, flaking or scaling of the skin, and a lump or swelling under the arm.
