Paget disease of the breast (also known as Paget disease of the nipple and mammary Paget disease) is a rare type of cancer involving the skin of the nipple and, usually, the darker circle of skin around it, which is called the areola. Most people with Paget disease of the breast also have one or more tumors inside the same breast. These breast tumors are either ductal carcinoma in situ or invasive breast cancer. Paget disease of the breast occurs in both women and men, but most cases occur in women
Statistics: The 5-year relative survival for all women in the United States who were diagnosed with Paget disease of the breast between 1988 and 2001 was 82.6 percent. This compares with a 5-year relative survival of 87.1 percent for women diagnosed with any type of breast cancer. For women with both Paget disease of the breast and invasive cancer in the same breast, the 5-year relative survival declined with increasing stage of the cancer (stage I, 95.8 percent; stage II, 77.7 percent; stage III, 46.3 percent; stage IV, 14.3 percent). Approximately 1 to 4 percent of all cases of breast cancer also involve Paget disease of the breast. The average age at diagnosis is 57 years, but the disease has been found in adolescents and in people in their late 80s. In 2010, breast cancer cost $16.5 billion in direct expenses in the U.S.
Treatment of paget's disease of the breast: Breast cancer treatment involves surgery, chemotherapy, hormonal therapy and radiotherapy. The sequence in which they are recommended may differ depending on the severity of the cancer. The most common order of treatment is surgery followed by chemotherapy, radiotherapy and then hormonal therapy.
