It's not clear what causes inflammatory breast cancer.
Doctors know that inflammatory breast cancer begins with an abnormal cell in one of the breast's ducts. Mutations within the abnormal cell's DNA instruct it to grow and divide rapidly. The accumulating abnormal cells infiltrate and clog the lymphatic vessels in the skin of your breast. The blockage in the lymphatic vessels causes red, swollen and dimpled skin — a classic sign of inflammatory breast cancer.
