Paget’s disease of the nipple, also called Paget’s disease of the breast, is an uncommon type of cancer that forms in or around the nipple (1, 2, 3). More than 95 percent of people with Paget’s disease of the nipple also have underlying breast cancer; however, Paget’s disease of the nipple accounts for less than 5 percent of all breast cancers (1). For instance, of the 211,240 new cases of breast cancer projected to be diagnosed in 2005, fewer than 11,000 will also involve Paget’s disease of the nipple (4).
