Inflammatory breast cancer is a rare and aggressive form of breast cancer. It accounts for 1% to 5% of all breast cancer diagnoses in the United States and is most common in women under the age of 60.

Inflammatory breast cancer is associated with “peau d’orange” (French for “skin of an orange”)— a visible swelling and dimpling of the skin over the breast, due to a blockage of lymph vessels, that may resemble the skin of an orange. Inflammatory breast cancer has a 70% higher incidence in Black women when compared with White women.
