New research led by ACS estimates more than 3.8 million lung cancer deaths were averted and a little over 76 million years of life gained in the United States during 1970-2022 due to substantial reductions in smoking prevalence driven by tobacco control. The study is published March 25 in CA: A Cancer Journal for Clinicians.
“The substantial estimated numbers of averted lung cancer deaths and person-years of life gained highlight the remarkable effect of progress against smoking on reducing premature mortality from lung cancer,” said Dr. Farhad Islami, senior scientific director, cancer disparity research, and lead author of the study. “However, despite these findings, lung cancer is still the leading cause of cancer death in the United States, and smoking-attributable morbidity and mortality from other cancers or diseases remain high.”
“Reducing smoking through tobacco control has saved millions of lives and can save millions more in the future,” Dr. Islami added. “But we need a stronger commitment at the local, state, and federal levels to help further reduce smoking and substantially augment the progress against smoking-related mortality. It’s also important that these tobacco control programs be designed to reach groups at a higher risk of smoking, such as people of lower socioeconomic status, to help save even more lives. For example, smoking prevalence and lung cancer mortality rates in individuals with a high school diploma or lower education levels are 5 times higher compared with individuals with a college degree.”
“Increased and sustained funding for evidence-based tobacco prevention and cessation programs is needed now more than ever as part of a comprehensive approach to reducing tobacco use and, ultimately, the cancer burden for everyone in the US,” said Lisa A. Lacasse, president ACS CAN, “The study’s findings show the impact of past tobacco control measures but also underscore the preventable deaths that continue to persist. Access to barrier-free, culturally competent cessation services, substantially increasing tobacco taxes, and implementing comprehensive smoke-free policies are proven policies to help people quit and prevent people, especially youth, from ever starting.”
Other ACS researchers contributing to the study include Dr. Nigar Nargis, Dr. Qinran Liu, Dr. Priti Bandi, Rebecca L. Siegel, Dr. Parichoy Pal Choudhury, and senior author Dr. Ahmedin Jemal.
