Questions to ask your doctor
Practical prompts for your next visit
Not a script — a starting point. Bring the ones that matter to you.
Which subtype do I have (adenocarcinoma, squamous, or other)?
What stage is it, and has it spread outside the lung?
Has my tumor been tested for biomarkers like EGFR, ALK, or PD-L1?
Biomarker results open up targeted therapies and immunotherapies for some patients.
Am I a candidate for surgery, radiation, targeted therapy, or immunotherapy?
Are there clinical trials for my subtype or biomarker profile?

Research and clinical trials
When research may be worth considering
