IBC stands for Inflammatory Breast Cancer, which is a rare and aggressive form of breast cancer that affects the skin of the breast and causes symptoms similar to a breast infection. IBC accounts for only 1% to 5% of all breast cancers. Unlike other types of breast cancer, IBC tends to grow quickly, is more likely to have spread at the time it’s found, and is more likely to come back after treatment. Symptoms of IBC include rapid swelling and redness that affect a third or more of the breast, and because it is often misdiagnosed as a breast infection or mastitis, it is important to have a correct diagnosis as soon as possible. Treatment for IBC usually involves chemotherapy, surgery, and radiation therapy. It is important to seek treatment early, as IBC progresses rapidly and often returns after treatment.
