Gum cancer may affect the normal life expectancy of the patient. Gum cancer is a malignant tumor disease caused by malignant lesions in the gum area, which is one of the types of oral cancer. If patients with gingival cancer do not receive timely treatment, the further development of the disease will not only lead to serious lesions in the lesion area, but also the tumor cells will metastasize to lymph nodes in the later stage of the disease development, resulting in the quality of life and life expectancy of patients being affected. In addition, according to Oral and Maxillofacial Surgery, the five-year survival rate of gingival cancer is only 50% to 70.4% when it is treated by surgery. The impact of gum cancer on an individual’s life expectancy cannot be ignored. It is important to pay attention to the prevention of gum cancer and to take good care of oral hygiene to prevent malignant lesions from occurring. If there are abnormal lesions inside the mouth for a long time, it is recommended to consult a doctor in time.
