No, COPD is a condition, not a disease. COPD is caused by many things, but generally it just "is". My wife has it, and, in her case, its underlying cause is frankly quite esoteric.
If your husband had lung cancer, that's what the doctors would say. If they're not talking about any underlying disease, there's nothing for you to worry about.
Breathe and be calm.
