Why do some people smoke 2 packs a day til theyre 85 and never get cancer, while others smoke 1 pack a day and get cancer at 58? genetics?

Yes: Yes, genetic is an important part in the etiology of cancer. Since you do not know how your genes are going to behave, it is prudent to avoid tobacco and alcohol, the two commonest causes of cancer.
