What causes breast nodules?

The causes of breast nodule formation are complex and varied, mainly including the following aspects: 1. Endocrine disorders: The occurrence of breast nodules is closely related to the level of estrogen in the body. When estrogen secretion becomes disordered, prolonged stimulation of breast tissue can easily lead to nodule formation. 2. Genetic factors: Family heredity is an important cause of breast nodules, and individuals with a family history have a higher risk of developing these nodules. 3. Unhealthy lifestyle habits: Long-term late-night activities, unbalanced diet, lack of exercise, and other unhealthy lifestyle habits may also affect breast health and increase the risk of nodule development. 4. Psychological factors: Long-term states of tension, anxiety, depression, and other negative emotions may lead to liver qi stagnation, affecting breast blood circulation and thus inducing nodule formation.
