The survival time of patients with advanced tongue cancer mainly depends on the serious nature of tongue cancer and the treatment effect. Roughly speaking, the survival time of patients with advanced tongue cancer is generally six months to about two years after surgery. If tongue cancer is not treated, it will easily lead to tumor spread and metastasis, resulting in cachexia, which may lead to death in three months to a year in the short term. If detected early, surgically removed, and treated systematically with post-operative radiotherapy, the survival rate can reach 50%-100% five years after surgery and 30%-85% eight years after surgery. Tongue cancer is a malignant tumor, mostly occurring on the lateral edge of the tongue, followed by the tip of the tongue and the back of the tongue, often of ulcerative type, with rapid growth, obvious pain, strong infiltration, and can be accompanied by neurological symptoms, such as limited tongue movement, difficulty in eating and swallowing, etc. Lymph node metastasis often occurs early, and can metastasize to the opposite side, and is prone to recurrence.
