Why is it easy to get breast cancer when you are older and unmarried

The probability of older unmarried women suffering from breast cancer is relatively high, which is mainly related to hormone level, fertility factors, lifestyle, psychological pressure, genetic factors, etc. The occurrence of breast cancer is the result of a variety of factors, and unmarried status may increase the risk through a single or complex way.

1. Hormone levels

Women who have not given birth or have given birth late have a longer exposure time to estrogen in their bodies, which prolongs the stimulation of estrogen on breast tissue during early menarche and late menopause. Excessive levels of estrogen may promote abnormal proliferation of breast cells, and long-term accumulation may increase the risk of cancer. Regular breast examinations can help detect abnormalities early.

2. Fertility factors

Pregnancy and lactation can cause breast cells to differentiate and mature, reducing sensitivity to carcinogens. Women who have not experienced full-term pregnancy lack this protective mechanism, and breast epithelial cells are more prone to accumulate gene mutations. Birth at the right age can reduce the risk of some breast cancer through physiological changes.

3. Lifestyle

Unmarried women may be more inclined towards high-fat diets, lack of exercise, alcohol consumption, and other lifestyle habits. These behaviors may lead to obesity, as adipose tissue secretes additional estrogen. Maintaining regular exercise, controlling weight, and limiting alcohol intake can help regulate endocrine balance.

4. Psychological stress

Social public opinion and family pressure may keep unmarried women in a chronic stress state for a long time, leading to elevated levels of stress hormones such as cortisol. Continuous psychological stress may affect immune surveillance function and weaken the body's ability to clear abnormal cells. Mindfulness based stress reduction and other psychological adjustment methods can improve physical and mental well-being.

5. Genetic factors

BRCA1/2 and other gene mutation carriers have significantly increased their own risk of breast cancer, and unmarried status may overlap genetic susceptibility. People with a family history should strengthen genetic testing and breast monitoring, and preventive measures may be considered if necessary. Genetic counseling helps assess individualized risk.

Regardless of marital status, it is recommended that all women undergo annual breast clinical examinations and increase mammography screening for those over 40 years old. Maintain a balanced diet, consume more cruciferous vegetables and whole grains, and limit processed meat. Regular aerobic exercise for at least 150 minutes per week, avoiding staying up late and smoking. The cure rate of early breast cancer is higher when abnormal breast masses and skin depressions are found. Psychological health is equally important and can be alleviated through social support, hobbies, and other means to maintain overall physical and mental health.
