Breast cancer is a malignant tumor occurring in the glandular epithelium of the breast, which seriously threatens women’s health and life. The causes of morbidity of breast cancer are complex and not yet fully clear, but mainly involve the following aspects: First, genetic factors. About 5% to 10% of breast cancer cases are related to genetic mutations. BRCA1 and BRCA2 gene mutations are the most common. If there are breast cancer patients in the family, especially immediate relatives such as mothers and sisters, the risk of breast cancer will increase significantly. Women with these mutations may have a 50 to 80% lifetime risk of developing breast cancer. In addition, there are other rare genetic mutations that may also be associated with the morbidity of breast cancer. Hormone levels. Hormone levels in women play an important role in the development of breast cancer. Early menarche (less than 12 years old) and late menopause (more than 55 years old) can prolong women’s exposure to estrogen and increase the risk of morbidity of breast cancer. Women who have not given birth, those who have given birth late (first birth after the age of 35) and those who have not breastfed are also more likely to develop breast cancer because of changes in hormone levels. Long-term use of drugs containing estrogen and progesterone, such as certain birth control pills and hormone replacement therapy, may also increase the risk of breast cancer. Third, lifestyle factors. 1. Bad eating habits are an important factor. Long-term intake of high-fat, high-calorie food can lead to obesity, which can affect hormone levels in the body and increase the risk of morbidity of breast cancer. At the same time, lack of dietary fiber and intake of fresh vegetables and fruits may also affect the body’s metabolism and immune system function. 2. Lack of exercise is also a risk factor. A sedentary lifestyle can lead to slower body metabolism, fat accumulation and hormone balance. Moderate exercise can enhance the body’s immunity and reduce the morbidity risk of breast cancer. 3. Long-term drinking increases the morbidity risk of breast cancer. Alcohol can affect the metabolism of hormones by the liver, resulting in increased estrogen levels in the body. 4. Radiation exposure. Women who have had radiation therapy to the chest have an increased risk of breast cancer. In particular, women who received radiation therapy at a young age are at higher risk. 5. Benign breast diseases. Some benign breast diseases, such as breast atypical hyperplasia and breast fibroma, may increase the risk of morbidity of breast cancer if they are not treated in time or exist for a long time. In a word, the morbidity of breast cancer is the result of many factors. Understanding these causes of morbidity can help women take active preventive measure, such as maintaining a healthy lifestyle and regular breast examinations, to reduce the morbidity risk of breast cancer.
