Can lung cancer thats spread to chest be cured?

Depends : The prognosis of primary lung cancer is determined by the staging which depends on the type of lung cancer (small versus non-small cell). Lung cancer staging has become very specific and can sometimes be pretty complicated. To answer your question (strictly speaking) there are forms of "spread to chest" that can be cured...But to be more accurate your oncologist/surgeon should answer that for you.

Depends: Lung cancer can go from localized (stage 1) to wide- spread (stage iv). If it goes from involving one lobe only, to more than one lobe, the lymph nodes in the chest, the other lung, the chest wall, or the other structures in the chest, the chances of cure drop significantly. Lung cancer is best treated when it is found early, and the most successful treatment is surgery.
