Breast cancer, commonly known as breast cancer, is a common malignant tumor in women, which originates from the uncontrolled proliferation of breast epithelial cells. High risk factors for cancer include heredity and estradiol exposure, such as early menarche, late menopause, infertility, and radiation exposure to the chest during childhood. In addition to high risk groups, late development, long lactation, and early childbearing have a chance of reducing breast cancer.

The age of onset increases year by year from the age of 20, reaching the highest point in 45-50 years. It ranks first in the world for female killers. China accounts for 30% of the world's breast cancer cases, and has been increasing year by year in recent years.
