Breast cancer is related to anger. Generally speaking, breast diseases related to bad mood are mainly seen in cystic hyperplasia or lobular hyperplasia in young and middle-aged women. Therefore, patients with cystic hyperplasia need to relax and avoid excessive anxiety and exertion. If necessary, oral Chinese medicines such as Prozac can be taken to relieve clinical symptoms and cure the disease without surgery. The risk factors of breast cancer are mainly related to high fat diet, obesity, early menarche and late menopause, as well as family genetic susceptibility and mental factors such as long-term depression.
