Tongue cancer treatment is based on the stage of the disease when it is diagnosed. The stage of the tongue cancer is designated based on the size and how far the tumor has extended or spread. The main standard methods of tongue cancer treatment are the radiation therapy, chemotherapy, and surgery.
However, lumps or lesions due to tongue cancer are not always painful. Other symptoms of tongue cancer can include swollen lymph glands, especially in the neck. This is called lymphedema and may be a sign that the tongue cancer has spread beyond the tongues into the deeper tissues of the mouth and neck.
