Breast cancer
April. 04,2023
Breast cancer is a phenomenon in which breast epithelial cells proliferate out of control under the action of a variety of carcinogenic factors. The early stage of the disease often manifests as breast lumps, nipple discharge, axillary lymphadenopathy and other symptoms. In the late stage, cancer cells may metastasize to a distance, and multiple organ diseases may appear, which directly threaten the life of the patient.
