Breast cancer is a chronic disease. Breast cancer is a body cancer and the 5-year survival rate of early breast cancer is over 98% and the 10-year survival rate is 95%. It even has a longer survival time compared to severe hypertension, diabetes, heart disease, etc. Then the key to get longer survival for breast cancer is early detection and early treatment, and to standardize treatment. Choose the right treatment and review regularly to prevent recurrence or metastasis and avoid long-term side effects of treatment that affect health. Many early stage patients do not recur or metastasize and reach the state of cure. Even patients with advanced breast cancer (meaning breast cancer with distant metastasis) have a longer survival period than patients with other tumors. For example, the survival period of patients with advanced lung cancer and stomach cancer may not pass one year, but the survival period of patients with advanced breast cancer can reach three or four years of survival, and some patients survive for five or ten years, or even longer. Many breast cancer patients are likely to have their disease effectively controlled, and some of them can even survive with tumors for a long time. Nowadays, many experts believe that advanced breast cancer should be treated as a chronic disease, and the treatment plan should be adjusted and the progression of the disease should be controlled through continuous medication adjustment and timely follow-up. Treatment for recurrent/metastatic breast cancer is aimed at improving survival, and treatment is aimed at relieving symptoms, preventing complications, improving quality of life, and prolonging survival. Patients with breast cancer should really understand the disease, establish confidence in treatment, cooperate with treatment and live a healthy life, and never be intimidated by the disease. Healthy people should live a healthy life, prevention is the main focus, regular medical checkups, avoid unnecessary worries, not to be influenced by what has not happened, and not to panic. Many patients, especially early stage patients, can expect a 30-year survival.
