Is it unusual for a lung cancer patient to have surgery with no radiation?

No: Early stage lung cancer is often treated by surgery alone.

No: Ideally we woul like to do surgery on lung cancer which means the cancer was resectable. In these cases the disease will be early stage and not require further therapy.

Depends on stage: Early stage lung cancer (stage i and ii) the standard therapy for the physically fit patient is upfront surgery. If there is cancer found in the lymph nodes after the operation, than adjuvant chemotherapy may be indicated (adjuvant = after surgery). If all of the tumor was removed, radiation is not generally required.
