Mitigating the adverse health effects and costs associated with smoking after a cancer diagnosis

Smoking after a cancer diagnosis causes adverse outcomes and is associated with substantial additional treatment cost. Mitigation of the adverse effects of smoking require active commitment from health systems, providers, and patients. Three areas of mitigation are discussed: (I) smoking cessation after a cancer diagnosis to improve cancer treatment outcomes; (II) identifying optimal cancer treatment strategies for patients who smoke at the time of diagnosis; and (III) how health systems can prioritize the effect modification caused by smoking. As innovation continues for healthcare delivery, priority should be placed on interventions that reduce the effect modification and associated costs caused by continued smoking after a cancer diagnosis.
