The cause of mammary eczema-like carcinoma is not clear, and the main symptoms are thickening and erosion of nipple. Patients can take surgical treatment and radiotherapy as prescribed by doctors. Eczema-like breast cancer is a special type of breast cancer, the cause of which is still unclear. The main manifestation of patients is itching and reddening of nipple, followed by localized roughness, thickening and erosion of skin, even localized scabs, flakes or exudates, and the lesions can gradually involve areola skin, and localized lymph node enlargement will also be accompanied during the period of illness. Usually, the malignant degree of breast eczema-like carcinoma is low and the disease progresses slowly, but patients still need active treatment. When the lesion is limited to the nipple, the patient can seek treatment by simple mastectomy, and when the areola is involved, modified radical surgery can be performed. In addition to surgical treatment, patients with eczema-like breast cancer can also be treated with radiation therapy and chemotherapy. It is suggested that those who are diagnosed with breast eczema-like cancer should adjust their mindset, actively cooperate with doctors and have regular medical checkups. In daily life, they should strengthen local skin care and try to wear cotton and loose underwear.
