The survival time of gum cancer patients is related to many factors, such as the stage of the disease, the location of the disease and the treatment. Gum cancer is a kind of oral squamous cancer, the incidence rate of lower gum is higher than that of upper gum, and the incidence rate of male is higher than that of female, and the survival time of patients is related to the disease stage, incidence site and treatment, etc. Lower gum cancer is more malignant than upper gum cancer and may metastasize earlier, which has more influence on the survival time of patients. Surgery is the main treatment mode of the disease, and timely surgery in early stage without metastasis has better effect, and the 5-year survival rate of patients can exceed 70%. If the tumor has already spread or metastasized at the time of discovery, the survival time of patients will be greatly shortened. In addition to taking medication strictly according to medical advice, patients should also have a light diet, quit smoking and drinking, and have regular review during treatment, which will have a positive effect on prolonging survival time.
