PHILDALPHIA - The science has long been clear that smoking causes cancer, but new research shows that children could inherit genetic damage from a father who smokes. Canadian researchers have demonstrated in mice that smoking can cause changes in the DNA sequence of sperm cells, alterations that could potentially be inherited by offspring. The results of their study are published in the June 1 issue of Cancer Research, a journal of the American Association for Cancer Research.
