| According to a study: Earlier a person begins to smoke, the more genetic damage they are likely to suffer, increasing their risk for cancer. The findings suggest that adolescents may be handicapping themselves for the rest of their lives in terms of their ability to recover from the damage tobacco can produce. All smokers develop DNA damage, a precursor to cancer, and all smokers who quit show some DNA repair. But smokers who picked up the habit at a very young age, around ages 9 to 12, showed the highest amount of DNA damage. |
