Is it a bad idea for me to put off my lung cancer surgery for 6 weeks?

Depends on the stage: Earlier lung cancers that don't require concurrent chemotherap and/or radiotherapy, 6 weeks is ok. Though you would not want to wait 3 months or more. More advanced stages of lung cancer that require chemotherapy and/or radiation, often it is a good idea to move along with therapy.

Does it make...: The difference between cure and failure to wait 6 weeks? Probably no. Cn the confined to cancer spread to nodes or somewhere else, perhaps. Fear of the procedure, surviving it, and desire to do something fun can fuel this idea. Is it yours, your partner's, your kids, friends? Lung cancer is not a gentle or considerate monster. Have a great reason for delay or get it over.

Many be too long: Depends on extent of disease and if there are any symptoms.
