Size of my spots in the right lung are 1.5cm and 0.9 cm. why not surgery versus chem/radiation, targeted drugs/cyber knife?

Whoa, many ?s here.: First gotta find out what they are. Has you had a biopsy? If not then ask your doctor(s) about starting there. If you and your lungs are healthy, and all the lung cancer (if present) is in the one lung, then surgery is an option. If it has spread to nodes in the middle of the chest, surgery up front is not helpful. You can always get a 2nd opinion, but start by asking your doctor these questions.

Depends on details: In the medically fit individually, the standard of care upfront therapy for stage i -iib nsclc is surgery. For stage iiia either chemotherapy +/- radiation followed by surgery or chemoradiation alone. For stage iiia - iv, therapy is chemotherapy +/- radiation. Even if there are two nodules, if in the same lobe, or considered synchronous primaries, surgery may be an option.
