Smoking and cancer: If we knew the answer to this question we would know when to start the screening. Not everyone who smokes gets lung ca.It depends on how much smoking the person has done.Someone who smokes 3 packs a day will have a greater chance.Alsodepends on length of time, longer is worse.And then there are all the individual factors..Eachca is unique to the person who has it.This is where ur genetics come in.
