For the first time UK scientists have found evidence of epigenetic changes from smoking that causes cancer. The results were reported at the 35th Congress of the European Society for Medical Oncology (ESMO) in Milan, Italy. We all have known that cancer was linked to smoking but now we can actually see the methylation caused by cancer and compare them to the cell methylation of a normal non-smoker. Smoking introduces a foreign toxin to the body that triggers epigenetic changes in our cells that can turn ON cancer cells. I find it shocking to see how many young people are smoking again.
