Influence of tobacco smoke on genes
A new research report suggests that tobacco smoking alters several genes that can be associated with health problems for smokers, such as increased risk for cancer and diabetes.
Whilst our genetic code is set by what we inherit from our parents, genetic material can be changed by epigenetic modifications. These are chemical alterations of the DNA the affect the activity of the genes. Triggers for this can include lifestyle factors, diet; or from exposure to radiation or to carcinogenic agents.
