How is breast cancer caused

What causes breast cancer? The occurrence of breast cancer is mainly related to genetic factors, hormone levels, environmental factors, lifestyle habits, and childbearing and breastfeeding. It is recommended to seek medical treatment in time and take appropriate treatment measures according to different situations. The details are as follows:

1. Genetic factors: The occurrence of breast cancer is related to family inheritance. BRCA1 and BRCA2 gene mutations are the main genetic factors. Women with a family history of breast cancer should undergo regular breast cancer screening to detect potential risks as early as possible.

2. Hormone levels: Long-term exposure to high levels of estrogen and progesterone can increase the risk of breast cancer. Use hormone replacement therapy appropriately, avoid long-term use of birth control pills, and check hormone levels regularly.

3. Environmental factors: Harmful substances in the environment, such as radiation and chemicals, can induce breast cancer. Try to reduce exposure to harmful substances, pay attention to occupational protection, and maintain a healthy lifestyle.

4. Lifestyle: Bad lifestyle habits such as high-fat diet and lack of exercise can also increase the risk of breast cancer. Maintain a balanced diet, increase physical activity, control weight, and avoid smoking and alcoholism.

5. Childbirth and breastfeeding: Women who have not given birth or breastfeeding have a higher risk of breast cancer. Encouraging women of childbearing age to give birth and breastfeed can help reduce the risk of breast cancer.

To prevent breast cancer, women should regularly perform self-examinations and medical examinations and pay attention to healthy lifestyle management. If symptoms persist, it is recommended to seek medical attention in a timely manner and take targeted treatment measures under the guidance of a doctor.
