I lived with my sons grandparents for about 6 years in the early 90′s and the grandfather passed away from asbestos cancer in his stomach about 12 years ago. Knowing that our clothes were washed together and being a part of the household, would it be possible? My son brought it up today and now it has concerned me.

What are the chances of getting lung cancer before the age of 20?
Can you get it after smoking 2, 4 or 6 years?
And back to my original question, can chronic bronchitis turn into lung cancer?
