Breast cancer is the most common malignant tumor of the female reproductive system with a high incidence rate and is one of the main causes of cancer-related deaths in women. Modern research believes that pregnancy, breastfeeding, and other reproductive behaviors can cause the changes in the levels of female estrogen and progesterone and related receptors, and affect the morphology and function of breast tissue, which are associated with the occurrence of breast cancer. This paper aims to summarize the impact of breastfeeding on the occurrence of breast cancer and analyze their correlation to increase the maternal breastfeeding rate, reduce the occurrence of breast cancer, and lower the risk of breast cancer in women.
