Breast cancer is something women think they know all about: Look for lumps; have mammograms; see our doctors.

But none of that will save you from one silent breast cancer killer that women know virtually nothing about. It's called "inflammatory breast cancer," and it's something every woman must know about.

Inflammatory breast cancer is an especially aggressive type of breast cancer that can occur in women of any age (and, although extremely rarely, in men). It is unique because it often does not present with a lump and therefore often is not detected by mammography or ultrasound.
