Inflammatory breast cancer (IBC) is an aggressive malignancy that metastasizes rapidly. According to the American Cancer Society, inflammatory breast cancer is rare in that it is responsible for approximately 1 percent of all diagnosed breast cancer cases in the U.S. In this cancer, the cancer cells block the lymphatic vessels located in the near the malignant breast. This form of cancer may be delayed in its diagnosis, because inflammatory signs are displayed rather than the typical development of a lump or solid mass.
Swelling
In inflammatory breast cancer, the affected breast begins to show signs of inflammation such as swelling. According to the Mayo Clinic, the swelling can occur in just a matter of a few days or weeks. The enlarged breast is not only noticeably larger, but also patients report that it feels heavier than the other breast.
Pain and Tenderness
The signs of inflammation in an area, that is, swelling, redness and feeling warm or hot, may cause pain for an individual with this rare type of cancer. The pain is individual to each case and may vary from being tender to touch, an aching sensation or to that of experiencing of sharp pain. Additionally, the skin of the affected breast may itch and feel uncomfortable similar to mastitis. Mastitis is an inflammation of the breast that is seen commonly among women who breastfeed.
Enlarged Lymph Nodes
The lymphatic system, part of the immune system, is spread throughout the body and includes the lymph nodes and lymph vessels. With the blockage of the lymph channels by the cancer, the lymph nodes near the breast, such as under the arms, may enlarge and become tender.
Skin and Nipple Changes
Inflammatory breast cancer produces noticeable skin changes of the breast, and one of the most common is in the color of the skin. The skin becomes discolored and may appear red, pink or purple in color. The discoloration can look like bruised tissue. Moreover, instead of the usual smooth skin, the breast may take on a rough and dimpled texture that is easily seen and felt. The nipple is frequently is affected; for example, the areola may change with this form of cancer. The nipple may invert or flatten out. Due to the aggressiveness of this cancer and its similarity to mastitis, any rapid breast changes like those listed should be evaluated immediately by a physician without delay.
