Professor Dennis explains that the implications of smoking cessation are profound and this is the most readily identifiable cause of lung cancer and is clearly something where one can intervene.

Phillip Dennis, M.D., Ph.D. is head of the Signal Transduction section medical oncology at the National Naval Medical Center. He is interested in how components of tobacco smoke activate signaling pathways that allow cancer cells to evade programmed cell death (apoptosis). “The implications of smoking cessation are profound. This is the most readily identifiable cause of lung cancer and is clearly something where we can intervene. In fact, in the state of California, they have been successful in decreasing the prevalence of smoking from 24% – which is on the national average – to about 12%. Aggressive anti-smoking campaigns that are comprehensive in their approach can do more to decrease the rate of lung cancer than any other intervention.”
