Hi Tony,

Obviously no doctor here but throwing 2 bits in anyway. You are T2n0 which means the primary tumor is pretty small and no metastasis at all so there is good reason to believe the cancer has not spread at all anywhere, even microscopically.

Chemo can and is used to kill microscopic cancer that escapes from the primary. It also is used as a radiosensitizer to improve the radiation therapy.

Given the radiation can target the primary effectively quite well and low concern of micro cancers, it seems quite reasonable that your case does not warrant chemo dosing which does carry sometimes significant downside risks.
