Yes, but as you say, it is only cancer risk that stays the same, all the other nasty risks go down quickly. Also, I do think I right in saying that if you continue smoking after cancer treatment, your chances of recurrence go up.
On the other hand, I never smoked and got oral cancer. We are talking about percentages and risks here. All we can do is try to make the healthiest choices we can. - Now, I hope secondhand smoke does not cause cancer, my husband does not need to hear that, he already knows his smoking probably brought on a heart attack at a young age!
