Inflammatory breast cancer (IBC), or invasive breast cancer, is a type of breast cancer in which cancer cells affect the lymph system in the breast.
According to the National Cancer Institute, IBC is rare, accounting for only about one to five percent of all breast cancers, and it's an aggressive type of breast cancer that progresses rapidly.
Inflammatory breast cancer (IBC) can be difficult to diagnose because it typically does not present with a tumor or lump in the breast that can be felt or seen on a mammogram. Instead, IBC makes the skin of the breast red and feel warm much like an infection on another part of the body. These symptoms will prompt your physician to order further diagnostic testing.
IBC may start as invasive ductal carcinoma, which is a type of breast cancer that starts in the ducts of the breast and spreads to other breast tissue.
