Anger may be one of the triggers for the development of breast cancer, but it is not all due to anger. Breast cancer is related to genetic factors, living habits, endocrine and so on. 1. Hereditary factors: if there is a family history of breast cancer, the chance of breast cancer will be increased, and regular examination is needed. 2. Lifestyle habits: Anger, stress and irregular life may lead to higher incidence of breast cancer, which is also closely related to childbirth and breastfeeding. 3. Endocrine: female endocrine disorders can easily cause stimulation to the breasts and may lead to cancerous changes in breast tissues. The development of breast cancer may be related to the love of anger, but also related to family genes, women want to stay away from breast cancer as far as possible to maintain a good mood, do not sulk, and do regular medical checkups. If you find any uncomfortable symptoms in the breast area, go to a professional hospital in time to find out the cause of the disease and get treatment as soon as possible.
