Lung and Breast Cancer Prevention by an Integrated Intervention of Maternal Smoking Cessation and Breastfeeding

The intervention group will receive an integrated intervention of smoking cessation and breastfeeding: education and counseling, monitoring and feedback, and contingent financial incentives.

Participants in the control group will receive usual prenatal care from physicians, nurses, or social workers. They will receive best standard care on smoking cessation and breastfeeding, including referral to the New York State Smokers' Quitline and the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC).
