In inflammatory breast cancer, the breast looks red and swollen and feels warm. The redness and warmth occur because the cancer cells block the lymph vessels in the skin. The skin of the breast may also show the pitted appearance called peau dâ€™orange (like the skin of an orange). Inflammatory breast cancer may be stage IIIB, stage IIIC, or stage IV.
