Q. What is inflammatory breast cancer?
A. Inflammatory breast cancer is a form of breast cancer that causes breast swelling and skin changes.
Inflammatory breast cancer happens when a growth of cells forms in the breast tissue. The cells break away from where they start to grow and travel to the lymphatic vessels in the skin. The cells can block the vessels and make the breast skin look swollen. This skin on the breast might look pink, red, purple, or bruised, depending on your skin color.
