Cancer has been reported to be self-curing, but the chances are relatively low, and there is no clear data on the rate of self-curing. Cancer cannot be cured by itself without treatment, and you should not hope that it will be cured by itself, and you should actively cooperate with your doctor for treatment. Cancer is a malignant disease caused by a variety of factors, such as heredity, environment and gene mutation. It is almost impossible to recover from the disease on its own, and if it is not treated in time, it will jeopardize the patient’s life and seriously reduce the quality of life when the disease develops into an advanced stage. After diagnosis, patients should actively consult the doctor and follow the doctor’s instructions for reasonable treatment. The main treatment method is surgical resection, after which radiotherapy, chemotherapy, targeted therapy and other adjuvant treatments can be carried out according to the condition of the patient. After active treatment, a certain clinical cure rate can be obtained, and the earlier the staging, the better the prognosis. Therefore, we should strive for early detection, early diagnosis, early treatment, and timely cooperation with the treatment after diagnosis.
