Milan study says smokers who give up have higher risk of cancer due to cell repair mechanism leading to unrestrained cell growth. True?

Milan study says smokers who give up have higher risk of cancer due to cell repair mechanism leading to unrestrained cell growth. True?

Must be distorted: This is simply not true epidemiologically. As a pathologist, there's a lot more cell turnover in a current smoker's lung than there is after they stop. The molecular pathways of cancer are numerous and being clarified as we go, but this doesn't make sense. I've noticed over the years that medical research from italy in particular tends to get scrambled in the media even worse than other science. ...Read more

Do the risks of getting oral cancer increase for dip users or cigar smokers?

Would be best to quit.... If not, at least switch where you put oral tobacco, to minimize irritation in one specific spot in your mouth. ...Read more

I smoke one cigar a week. I don't inhale. Am i at a greater or equal to risk of getting cancer than a non smoker?

I smoke one cigar a week. I don't inhale. Am i at a greater or equal to risk of getting cancer than a non smoker?

Greater risk: Despite not inhaling, you are at greater risk than a non-smoker for getting cancer. Whereas you are not likely to get lung cancer if you dont inhale, you still are at risk of getting oral cancers of the lips, tongue, mouth lining, and even throat, what we often refer to as oropharynx cancers. The risk increases the more frequently you smoke the cigars. ...Read more

No data available: These products have not been available long enough,or studied well enough to answer this question.This product does not contain some of the dozens of toxic materials in inhaled spoke from regular cigarettes.However, the use of the lungs as an entry point for this or any drug exposes the lung tissue to damage, if that substance can do so on a cellular level. ...Read more

If I live under a family of smokers, am I putting my children at serious risk of cancer from second hand smoke?

If I live under a family of smokers, am I putting my children at serious risk of cancer from second hand smoke?

Yes!: Not only are you exposing them to 2nd hand smoke which is bad, but also 3rd hand smoke. The residual nicotine & other chemicals left on a variety of indoor surfaces by tobacco smoke is referred to as thirdhand smoke. The combination of this residue & common indoor pollutants creates a toxic mix of cancer-causing substances. These pose a potential health hazard to nonsmokers especially children. ...Read more
