No cancer can be diagnosed through physical examination. More so one that is internal.

If the scans are clear, where is he getting this diagnosis from? Even scans aren't used to give a definitive diagnosis. That's what biopsies are for.

Purely going from the information you have provided, where could they even take a biopsy from if there's nothing there? What led him to believe you have cancer? Have you had a lymph node (usually around the collarbone) out or any other strange swellings or outwardly signs?

This seems really bizarre. They can suspect you have a cancer, and some can give an educated guess before a biopsy has came back confirming such a thing, but yeah, lung cancer can share symptoms with many other more benign conditions.

I'm with Dor06 on this. I wouldn't be telling anyone you have cancer until they give you more of an explanation or even find something. Huge difference between "may have cancer" and "having cancer".

There is no way a doctor can diagnose lung cancer through a physical examination.
