I agree surgery is usually the first option in oral cancet, but not necessarily in all cases, like if it's unresectsble, patient is unfit for surgery, and don't know all the particulars. Radiation is also an option, instead of surgery, for T1,T2 tumors, N0 neck, and also for T4b tumors, any N, which indicates systemic therapy, Induction Chemo, radiation, chemo alone, clinical trial, best supportive care in oral cancer, as per NCCN guidelines.
