Can doctors tell me what does lung cancer prevent you from doing?

Depends: That really depends on the stage of lung cancer. If it is early stage and it is treated, it can potentially be cured, and you can do lots of things...Live a normal life (with close and regular follow up). If it is more advanced, however, it may limit what you can do. But, again, it all depends on many factors. You need to be seen and regularly followed by your doctor.

Depends: Early on may be asymptomatic. As progresses, short of breath, limitation of activity, pain and early death are the natural history. Early identification and treatments can improve survival and control symptoms.
