lung spots

[Jackie434]

are all spots on the lungs cancer?  can bronchitis leave scar tissue on the lungs?

Oh, yes, and there can be (benign) calcifications.

[Giveypup]

No, not all spots (do you mean nodules?) are lung cancer--they can be bacterial (toxo, coxxy), scars from upper respiratory infections--bronchitis, pneumonia, etc.  In fact, a scar can morph, in a small percentage of people, into what's called a scar carcinoma.

Lung Cancer Alliance is a great resource for answering such questions, by the way.
