Inflammatory breast cancer is a rare but aggressive form of breast cancer. Accounting for less than 5% of all breast cancer diagnoses, the cancer forms in the cells that line the breasts’ milk ducts, but quickly spreads to nearby lymph nodes and sometimes other tissues in the body. The cancer is called “inflammatory” because the cancer cells usually block the lymph vessels in the breast. This causes fluid to build up, which leads to inflammation that is usually red and tender.

Compared to slower-growing forms of breast cancer, inflammatory breast cancer progresses and spreads through the body quickly – sometimes in a matter of weeks.
