The cause of ductal tumors is not yet known and may be related to increased estrogen levels, which are usually not caused by anger. Anger may cause mood disorders and changes in blood pressure, but it does not affect the ducts of the breast, so ductal neoplasms are not caused by anger. Ductal tumors are papillary tumors that occur in the ducts of the breast. The cause of these tumors is not yet clear, but they may be related to the perimenopausal period, when estrogen secretion is disrupted. The increase of estrogen level in the patient’s body will stimulate new expansion of the milk ducts, which will lead to abnormal proliferation of epithelial cells in the breast, thus triggering the disease. Patients with ductal reason should go to the hospital in time to take appropriate treatment for liver disease.
