It is certainly necessary to cure advanced cancer, and if the treatment is effective, it can also enable patients to obtain long-term survival and have a high quality of life. Many patients feel that there is no need to treat cancer when it reaches advanced stage, because it cannot be cured, so they give up and go home. The purpose of treatment for advanced cancer is no longer to remove cancer cells from the body to achieve a complete cure, but to control tumor growth so that patients can live with tumor for a long time and have a better quality of life, which is called palliative care. At present, many palliative treatment strategies for advanced cancer have good efficacy. Patients with advanced cancer can control the growth of cancer like controlling high blood pressure and diabetes, so that they can take care of themselves and live with tumor for a long time. In conclusion, not only is it necessary to treat advanced cancer, but some patients with advanced cancer can survive for a long time after treatment.
