Inflammatory Breast Cancer: Symptoms & Signs

Medically Reviewed on 9/10/2019

Inflammatory breast cancer is a rare type of breast cancer that spreads to the lymphatic system, causing signs and symptoms of inflammation in the involved breast. It is an aggressive form of breast cancer.

Many breast cancers do not cause symptoms or signs at diagnosis, but inflammatory breast cancer is different. It produces characteristic symptoms including swelling, warmth, and redness of the breast. Other associated symptoms can include pitting, skin changes, dimpling, bruising, inversion of the nipple, burning pain, tenderness, and a rapid increase in the size of the breast. Enlarged lymph nodes in the underarm or beneath the collarbone may be present.
