Survival Benefits of Smoking Cessation After Breast Cancer Diagnosis

[摘要] We now recognize that cigarette smokers have about a 10% increased risk of developing breast cancer over never smokers, albeit far from the 600% to 800%, or more, increased risk for cancers of organs in direct contact with carcinogens in smoke such as lung, head and neck, bladder, and others (1). For established smoking-related malignancies, continued smoking after diagnosis is associated with increased risk of disease progression and death (2), but much less is known about postdiagnosis smoking and outcomes for cancers, such as breast, for which smoking is not a particularly strong risk factor. Postdiagnosis assessments of smoking habits are frequently missed, both in the clinic (3) and as part of follow-up in longitudinal research studies (4), making it a challenge to estimate any association with change in smoking behavior.
