Who knows babe?
My dad smoked his last cigar at 85, 6 weeks before he died from a Heart Attack, not cancer!
But I'm 58 and terminal!
Everyone's different, cancer is not predictable, but if you don't want it, don't do anything which might pre-dispose you!
Tobacco is well-documented as a contributing factor!
Congrats for your 'process of quitting'
