Women’s anxiety, depression, family conflicts, unsatisfactory sex life, stressful life and work, and many other bad emotions can adversely affect the breasts and can induce mammary gland hyperplasia and even increase the incidence of breast cancer. 1. Induce mammary gland hyperplasia: Because long-term bad emotions can affect the endocrine system of the body and lead to endocrine disorders, which in turn cause the ratio of estrogen and progesterone to be out of balance and stimulate excessive proliferation of the breast parenchyma. This can lead to breast hyperplasia and symptoms such as breast swelling, pain, lumps and nipple overflow; 2. Therefore, long-term bad emotions lead to endocrine hormone imbalance, which can easily increase the incidence of breast cancer and lead to symptoms such as cellulite-like changes of breast, breast lumps and nipple retraction. Therefore, women’s bad mood has a certain adverse effect on breast health, and also affects other organs and systems in the body. It is recommended that women maintain a good state of mind, learn to self-adjust and release bad emotions, such as singing, chatting with others, exercising, etc., all help to detoxify bad emotions and have certain benefits for maintaining good health.
