After breast cancer surgery, chemotherapy and/or radiotherapy, how to further reduce recurrence? I. Adherence to endocrine therapy is the key (estrogen receptor positive patients) A large number of clinical studies have confirmed that endocrine therapy can significantly reduce the recurrence rate of estrogen receptor positive patients. Compliance with endocrine therapy is closely related to the prognosis, and it is important not to casually stop or casually change other endocrine therapy drugs during the treatment process, and to consult a specialist (preferably the doctor who knows your condition best) when changing drugs. Second, a healthy and good lifestyle: 1. Adhere to exercise A new study published by Dr. Brionna Hair of the Department of Epidemiology in the journal Cancer on June 9, 2014 shows that exercise can improve survival, reduce incidence and improve quality of life for patients with breast cancer. The amount of exercise doesn’t have to be too much, just walking or jogging for about 30 minutes a day, walking to work, biking to work, etc. are all good choices. Obesity is one of the risk factors for poor prognosis of breast cancer, and Dr. Joseph Sparano and his colleagues conducted a large sample clinical trial through the American Cancer Cooperative comparing the health status between obese and overweight patients and others with stage I-III breast cancer. The results showed that obesity can affect cancer recurrence and survival. Therefore, weight control is also an important measure to prevent recurrence. 3.Control alcohol consumption and smoking
