Chemotherapy is necessary for advanced cancer. The possibility of complete cure of cancer at advanced stage is very slim, but chemotherapy can still prolong the life of most patients and ensure a certain quality of life. The purpose of advanced cancer treatment is no longer to completely remove the malignant tumor cells in the body, but to control the growth of cancer so that patients can live with tumor, just like chronic diseases such as hypertension and diabetes, which cannot be cured but can survive for a long period of time and have a good quality of life. Besides chemotherapy, new treatment methods with less side effects such as targeted therapy and immunotherapy are also applicable to the treatment of advanced cancer patients, but due to the large tumor load in the body of advanced cancer, chemotherapy is still the most effective treatment method in most cases. In conclusion, don’t think that cancer is hopeless when it reaches advanced stage, if you can tolerate chemotherapy, playing chemotherapy is still very effective for prolonging survival and improving quality of life.
