Breast cancer is not contagious, but breast cancer can be inherited.
Breast cancer is a malignant tumor that comes from cells in the glandular epithelium or basal lamina of the breast, and it is not contagious. Even if the breast is locally broken and overflowing, the cancer cells cannot survive for too long outside the body at room temperature, and even if they soon enter the allograft, they will be destroyed by cells such as allograft leukocytes and phagocytes. But even though breast cancer is not contagious, various studies have now shown that there is a strong genetic link between the occurrence of breast.
There are several major causes of breast cancer:
1. Genetic factors: A family history of breast cancer is one of the reasons why breast cancer occurs, and a family history refers to a first-degree relative (mother, daughter, sister) with breast cancer.
2. Age: The current high incidence of breast cancer is between 45-55 years of age.
3. External factors: high doses of radiation to the chest, long-term use of exogenous estrogen, etc.
4. Obesity: obese women have a relatively higher incidence of breast cancer than the general population.
5. Psychosomatic factors: Patients with frequent anxiety, depression, and mood swings are more likely to develop breast cancer.
