How is breast cancer caused

Breast cancer is a common malignant tumor, usually caused by genetic factors, hormone levels, environment and lifestyle, age and family history. If you experience breast discomfort or suspicious symptoms, it is recommended to seek medical attention in time and take appropriate treatment measures according to the doctor's advice according to different situations. The details are as follows:

1. Genetic factors: The occurrence of breast cancer is closely related to family inheritance. BRCA1 and BRCA2 gene mutations are known high-risk factors. People with a family history of breast cancer should undergo regular genetic testing and breast examinations for early detection and prevention.

2. Hormone levels: Long-term exposure to estrogen and progesterone stimulation, such as long-term use of oral contraceptives or hormone replacement therapy, may increase the risk of breast cancer. Use hormone drugs under the guidance of a doctor and avoid long-term excessive use. If tamoxifen tablets or letrozole tablets are used during treatment, patients must use these drugs according to the doctor's instructions.

3. Environment and lifestyle: Bad living habits, such as smoking, drinking, unhealthy diet and lack of exercise, may increase the risk of breast cancer. Develop a healthy lifestyle, quit smoking and limit alcohol, maintain a balanced diet and exercise moderately.

4. Age: The incidence of breast cancer increases with age, especially in postmenopausal women. Older women should pay more attention to regular breast examinations to detect abnormalities as early as possible.

5. Family history: People with a family history of breast cancer have a significantly higher risk of developing the disease than the general population. People with a family history should be more vigilant, have regular breast examinations, and maintain good living habits.

In order to prevent and detect breast cancer early, it is recommended to perform regular breast examinations under the guidance of a doctor and maintain a healthy lifestyle.
