DEAR DOCTOR K:I saw my doctor because I've been getting short of breath. He did an X-ray and CT scan that found three small "pulmonary nodules." Do I have lung cancer?
DEAR READER: There are few things more frustrating, for both you and your doctor, than when the doctor says: "Well, it's almost surely nothing to worry about ... but there is a small possibility that it's bad." How often does that happen? Pretty much every day, in my experience.
