**4.11 Paget's disease of the breast**

It's an uncommon kind of breast cancer that produces visible changes to the breast's nipple. Red itchy rashes around the nipple, which may occasionally spread to the rest of the body, are among the symptoms. Paget's disease of the breast differs from other skin problems like eczema and psoriasis in that the other skin problems usually affect both breasts and can start at the areola rather than the nipple of the breast, whereas Paget's disease of the breast usually affects only one breast and starts at the nipple of the breast rather than the areola. Men and women are equally affected by Paget's disease, which contributes for 1–3% of all breast malignancies.
