Inflammatory breast cancer is a rare, fast-growing type of breast cancer. The cancer cells block the lymph fluid in the breast tissue and usually don't form lumps.

Symptoms include:

• Redness, tenderness, and warmth.
• Thickening of the skin of the breast (orange peel appearance).
• Rapid breast enlargement.
• Ridging of the skin of the breast.

Treatment involves chemotherapy, breast surgery, and radiation therapy. Afterwards, more chemotherapy or hormone therapy (or both) may be needed.
