Inflammatory breast cancer is a rare kind of breast cancer that develops rapidly, making the affected breast red, swollen, and tender. It occurs when cancer cells block the lymphatic channels in the breast-covering tissue, causing the breast to look characteristically red and swollen.
Inflammatory breast cancer is taken under consideration as a locally advanced cancer which suggests spread from its point of origin to nearby tissues and possibly to nearby lymph nodes.
If you notice changes in the skin on your breast, seek medical attention immediately.
