Inflammatory breast cancer is a unique and uncommon type of breast cancer. It is unique in that inflammatory breast cancer does not produce a distinct mass or lump that can be felt within the breast. The lack of a lump or mass also makes inflammatory breast cancer difficult to detect by mammograms. Inflammatory breast cancer cells infiltrate the skin and lymph vessels of the breast. When the lymph vessels become blocked by the breast cancer cells the breast typically becomes red, swollen, and warm. The skin changes associated with inflammatory can cause the breast skin to look like the skin of an orange a finding called peau d'orange. The appearance of the breast is similar to other inflammatory conditions such as cellulitis or mastitis. Other possible associate symptoms include enlarged lymph nodes under the arm or above the collar bone on the affected side.



Inflammatory breast cancer is diagnosed based upon the results of a biopsy and the clinical judgment of the treating physician. Typically, inflammatory breast cancer grows rapidly and requires aggressive treatment. There are two aspects to treating all breast cancer, local treatment and systemic or total body treatment. Because inflammatory breast cancer is aggressive, most oncologists recommend both systemic and local treatment. The typical sequence of treatment is to start with chemotherapy, systemic treatment, followed by surgery and radiation therapy, which are the local treatments, often followed by additional chemotherapy and possibly hormone treatments. With aggressive treatment using this multimodality approach, the 5 year survival for inflammatory breast cancer has improved significantly from an average survival of 18 months to an approximately 50% survival rate at 5 years.



How many cases of IBC are diagnosed each year?

The numbers vary, but approximately 1% to 2% of newly diagnosed invasive breast cancers (that have spread beyond the breast) in the United States are described as inflammatory breast cancers.
