Answer

Stereotactic body radiotherapy (SBRT) is another technique for nonoperative treatment of early-stage lung cancers. SBRT uses precise targeting of high-dose radiation to the tumor, typically in 1-2 fractions, while minimizing toxicity to normal tissues. Patients best suited for SBRT include those with a peripheral node-negative tumor that is less than 5 cm, in whom definitive surgery is contraindicated.
