Quiting smoking after lung cancer treatment doubles survival rates by reducing recurrence

In a study (published in January 2010), patients who quit smoking after treatment for early stage lung cancer had a doubling of their survival rates compared to those who did not quit. The authors report that this seemed to be due to a decrease in the rate of lung cancer recurrence in those who quit smoking.
This is an important study, as it shows that even after getting lung cancer our patients can double their chances of beating lung cancer by quiting smoking. (read more here)

Furthermore, another study (in mice) found that continued exposure to cigarette smoke after a lung cancer develops leads to more rapid growth of the tumor. (read more here)
