Bad mood and mentality, and frequent anger may be the high-risk factors for the development of breast cancer or ovarian cancer, but not the causative factors. Frequent bad moods and nervousness can easily affect the endocrine function, leading to changes in the secretion level of estrogen and other hormones in the body, which may induce breast cancer or ovarian cancer. However, it is not clear what the specific pathogenesis of breast cancer and ovarian cancer is. Women should keep a good mood, do not be angry, nervous and anxious, and should be careful to use health products containing large amounts of estrogen, so as not to cause excessive proliferation of breast epithelial cells. People with a family history of related tumors are advised to have regular medical checkups for early detection of the disease.
