Context: Treatment of Stage I Lip and Oral Cavity Cancer
Treatment options for stage I small lesions of the floor of the mouth include:
Surgery for patients with T1 lesions.
Radiation therapy is used to treat T1 lesions.
Excision alone is generally adequate to treat lesions smaller than 0.5 cm if there is a margin of normal mucosa between the lesion and the gingiva.
Surgery is often used if the lesion is attached to the periosteum.
Radiation therapy is often used if the lesion encroaches on the tongue.
