Itchy skin on the areola may be related to dry skin, eczema, breast cancer and other reasons. 1. Dry skin: In the fall and winter season, the air is cold and dry, which will cause some stimulation to the skin on the surface of the areola. The skin on the surface of the areola is too dry, which may lead to itchy skin. 2. Eczema: Eczema is a common clinical dermatologic disease. The occurrence of this disease may be related to contact with allergic substances, mental factors, genetic factors and so on. During the disease, small rashes will form on the surface of the areola and cause itching. 3. Breast cancer: Breast cancer is a malignant tumor that occurs in the breast. When breast cancer involves the areola and other parts of the breast, the malignant tissue will invade the skin, resulting in localized itchy skin. There may also be other clinical causes such as nipple inflammation, which can also lead to itchy skin on the areola. It is recommended to go to the breast surgery department of the hospital as soon as possible in order to clarify the cause of the disease.
