How is tongue cancer staged? How is tongue cancer treated at each stage?

Tongue cancer is divided into stage I, stage II, stage III and stage IV according to the size of the tumor, whether lymph node metastasis occurs, and whether distant metastasis occurs. Stage IV tongue cancer has the worst prognosis.

1. How is tongue cancer staged ? Tongue cancer is staged using the TNM stage system, which is based on tumor size, lymph node metastasis, and distant metastasis. Tongue cancer is divided into stages I, II, III, and IV. A tumor smaller than 2 cm without lymph node metastasis is stage I, and a tumor between 2 and 4 cm is stage II. Lymph node metastasis is stage III, and distant metastasis has occurred in stage IV.
2. How to treat tongue cancer at different stages? For stage I and II tongue cancer, the tumor is small and can be surgically removed. If the tumor develops to stage III, in addition to surgical treatment, chemotherapy or radiotherapy should be used. For stage IV tongue cancer, chemotherapy and radiotherapy can be used to prolong survival.
