diagnosed scc left anterior tongue. had mri,pet,xray 5 days ago. T2 prolongation and enhancement aprrox 1.2cm in thickness and 2.5cm in the AP extent. My oncologist says no surgery needed. Radiation and chemo(Erbitux) will cure me. Surgeon I consulted with prior to scans said I needed major surgery - nearly half tongue taken and plastic surgeon to replace with tissue from forearm, and 4-5 days in hospital. How can I resolve which treatment is correct?
