Inflammatory Breast Cancer
Inflammatory breast cancer (IBC) is a rare and aggressive form of breast cancer. It grows in a sheet-like shape.
Breast Cancer in Women
Breast cancer is a disease in which cancer cells grow in the breast tissue. It is the most common cancer in women in the US. The breast is made up of lobules, which make milk and ducts that allow milk to pass to the nipple. The lobules are surrounded by fat, connective tissue, blood vessels, and lymphatic tissue. Types of breast cancer include:
Breast Cancer in Men
Breast cancer is a disease in which cancer cells grow in the breast tissue. Although male breasts do not fully develop, they do contain most of the same basic breast structures as women. Male breasts include small glands called lobules, ducts, and the nipple. These structures are also surrounded by fatty tissue. All of these structures are susceptible to developing breast cancer. Breast cancer in men is rare. This makes awareness of the disease uncommon. Types of breast cancer found in men are:
Mastalgia is breast pain. There are two types:
Breasts are made up of ducts, milk glands, and fatty and fibrous tissues. Fibrocystic disease is when there are fluid-filled lumps (cysts) of duct tissue. These lumps are surrounded by a scar-like capsule of tissue in the breasts.
Mastitis is painful swelling and redness in the breast. It is most common among women who are breastfeeding. It usually occurs in one breast at a time, but it can occur in both breasts at the same time. Mastitis can occur in women who are not breastfeeding. However, this fact sheet will focus on symptoms and treatment of mastitis that occurs with breastfeeding.
Gynecomastia is an enlargement of the breasts in men. This condition is not the same as having a fatty breast area from obesity. The breast tissue is firm in men with gynecomastia. This may occur in up to one-third of men. More than half of boys will develop some degree of breast enlargement during puberty. This is normal and usually goes away by age 18.
