Breast cancer is the second largest tumor after cervical cancer among gynecological tumors, but generally speaking, the prognosis is good, especially for early stage patients, so it is important to stay calm and sensible when you have breast cancer, and after surgery in a regular hospital, you must undergo radiotherapy or chemotherapy according to the stage and oral hormone therapy if necessary. This is very important. On the basis of these, we should pay attention to the following points: a. Happy mood A good mood can maintain normal ovulation of the ovaries and normal secretion of progesterone, so that the breast gland will not be stimulated by estrogen and become hyperplastic or have tumor recurrence or metastasis, while a good mood can maintain normal immune function and strengthen its own anti-tumor ability, thus delaying the progress of the disease. Follow the principle of “low-fat and high-fiber” diet, eat more whole grains, control animal protein intake, and pay attention to the supplementation of appropriate trace elements. Consume more vegetable oils and less animal oils and margarine. Eat more live fish, fruits and vegetables. Third, regular checkups Do a monthly self-examination of the breast and armpit, and regular re-examination at the hospital (it is recommended to re-examine every 3 months for 2 years after post-operative radiotherapy, and once every six months after 2 years for stable conditions, and seek medical advice whenever there is a change in the condition). Proper exercise Some studies show that proper exercise can reduce the incidence of breast cancer. Performing regular physical exercise and adhering to 3-5 times a week suitable physical exercise can enhance physical fitness and avoid obesity and hormonal imbalance that cause immune function decline.
