Nearly half of all cancer deaths in the U.S. are preventable — and smoking is a leading risk factor

A new study by the American Cancer Society found that 44% of all cancer deaths among U.S. adults were attributable to lifestyle, with cigarette smoking taking the lead as one of the deadliest risk factors. The study also found that most cases and deaths were from lung cancer.

On World Lung Cancer Day, Aug. 1, organizations across the country are spreading awareness about the risk factors attributed to this deadly disease. The occasion also provides an opportunity to reflect on the role that tobacco continues to play in the consistently high rates of lung cancer cases and deaths.

Decades of research have established that smoking causes cancer — and yet, it’s proven difficult to knock out tobacco-related death and disease. Here are four important factors that must change to close the cancer gap and help Americans live longer, healthier lives.

Increase access to smoking cessation programs and resources. To reduce cancer rates, especially lung cancer, all people must be empowered to quit with free and easily accessible resources and programs. Digital programs as well as in-person programs should be made available to people from all backgrounds and identities.

Raise awareness about the importance of cancer screenings, especially in rural areas. Keeping up with routine doctors' appointments and undergoing routine cancer screenings are important factors in reducing the risk of cancer, especially for current tobacco users or people with a history of tobacco use. This is especially necessary for people living in rural communities for whom access to routine health care may be more limited.

Increase tobacco taxes in states with high smoking prevalence and strengthen local tobacco control policies. The research is clear: increases in cigarette taxes can have profound effects on cigarette use, particularly in areas where tobacco use is high. Increased cigarette tax revenue can also be directed toward tobacco control efforts to further magnify impact.

Focus on populations disproportionately affected by tobacco. Tobacco is not an equal opportunity killer. Black Americans, the LGBTQ+ community, and other vulnerable populations targeted by the tobacco industry have long faced a disproportionate burden from tobacco-related diseases and death. Increased taxes have a much greater impact on these groups, and policymakers should ensure that tobacco control policies and quitting programs are easily accessible for these populations.

According to Truth Initiative research, increasing spending on tobacco control and raising cigarette taxes in the 13 Midwestern and Southern states with the highest rates of smoking would help close the gap in adult smoking rates between this region and the rest of the U.S. and help address cancer cases and deaths. If implemented, these key policy changes could result in 100,000 fewer cancer cases over a 20-year period. As a nation, we must spread awareness about the role of tobacco use in cancer, empower people to quit, address disparities in health care, and build a healthier nation for all.
