American Cancer Society researchers stress the need for broad and
equitable implementation of known preventive initiatives to reduce
the risk of cancer<\/p>\n\n\n\n
ATLANTA, July 11, 2024 \u2014 A new study led by researchers at the American Cancer Society (ACS)
finds four in 10 cancer cases and about one-half of all cancer deaths in adults 30 years old and
older in the United States (or 713,340 cancer cases and 262,120 cancer deaths in 2019) could be
attributed to modifiable risk factors, including cigarette smoking, excess body weight, alcohol
consumption, physical inactivity, diet, and infections. Cigarette smoking was by far the leading risk
factor, contributing to nearly 20% of all cancer cases and 30% of all cancer deaths. The findings are
published today in the journal CA: A Cancer Journal for Clinicians .
\u201cDespite considerable declines in smoking prevalence during the past few decades, the number of
lung cancer deaths attributable to cigarette smoking in the United States is alarming. This finding
underscores the importance of implementing comprehensive tobacco control policies in each state
to promote smoking cessation, as well as heightened efforts to increase screening for early
detection of lung cancer, when treatment could be more effective,\u201d said Dr. Farhad Islami, senior
scientific director, cancer disparity research at the American Cancer Society and lead author of the
report. \u201cInterventions to help maintain healthy body weight and diet can also substantially reduce
the number of cancer cases and deaths in the country, especially given the increasing incidence of
several cancer types associated with excess body weight, particularly in younger individuals.\u201d
In this study, researchers used nationally representative data on cancer incidence and mortality
and risk factor prevalence to estimate the proportion and number of cancer cases and deaths
attributable to potentially modifiable risk factors overall (excluding non-melanoma skin cancers)
and for 30 cancer types. These risk factors included cigarette smoking (current and former
smoking); secondhand smoke; excess body weight; alcohol consumption; consumption of red and
processed meat; low consumption of fruits and vegetables, dietary fiber, and dietary calcium;
physical inactivity; ultraviolet (UV) radiation; and infection with Epstein-Barr virus (EBV),Helicobacter pylori, hepatitis B virus (HBV), hepatitis C virus (HCV), human herpes virus-8 (HHV-8;
also called Kaposi sarcoma herpesvirus), human immunodeficiency virus (HIV), and human
papillomavirus (HPV).
The results showed cigarette smoking had the largest population attributable fraction (PAF) or
proportion of cancer cases attributable to risk factors in the population (344,070 cases; 19.3% of all
cases), contributing to 56.0% of all potentially preventable cancers in men (206,550 of 368,600)
and 39.9% in women (137,520 of 344,740). Excess body weight had the second largest PAF (7.6%),
followed by alcohol consumption (5.4%), UV radiation exposure (4.6%), and physical inactivity
(3.1%).
By cancer type, the proportion of cases caused by potentially modifiable risk factors ranged from
100% for cervical cancer and Kaposi sarcoma to 4.9% for ovarian cancer and exceeded 50% for 19
of 30 evaluated cancer types. In addition to cervical cancer and Kaposi sarcoma, more than 80% of
all melanomas of the skin (92.2%) and cancers of the anus (94.2%), larynx (89.9%), lung and
bronchus (lung; 88.2%), pharynx (87.4%), trachea (85.6%), esophagus (85.4%), and oral cavity
(83.7%) were attributable to evaluated risk factors. Lung cancer had the largest number of cases
attributable to evaluated risk factors in both men (104,410 cases) and women (97,250), followed by
skin melanoma (50,570), colorectal cancer (44,310), and urinary bladder cancer (32,000) in men
and by breast (83,840), corpus uteri (35,790), and colorectal (34,130) cancer in women.
\u201cThese findings show there is a continued need to increase equitable access to preventive health
care and awareness about preventive measures. Effective vaccines are available for hepatitis B
virus, that causes liver cancer and HPV, which can cause several cancer types, including cervical,
other anogenital, and oropharyngeal cancers,\u201d added Dr. Ahmedin Jemal, senior vice president,
surveillance and health equity science at the American Cancer Society and senior author of the
study. \u201cVaccination at the recommended time can substantially reduce the risk of chronic infection,
and consequently, cancers associated with these viruses. HPV vaccination uptake in the United
State is suboptimal.\u201d
The American Cancer Society\u2019s advocacy affiliate, the American Cancer Society Cancer Action
Network (ACS CAN), advocates for policies at all levels of government to prevent and reduce one\u2019s
cancer risk, by making it easier for everyone to eat healthy, be physically active and by passing
comprehensive tobacco control policies. \u201cWe know that sufficiently funded evidence-based tobacco
prevention and cessation programs effectively prevent and address tobacco-related disparities by
reducing tobacco use,\u201d said Lisa Lacasse, president of the ACS CAN. \u201cThe cost to fully fund state
tobacco control programs is tiny compared to the cost of tobacco-caused diseases and the potential
tobacco-caused health care cost savings states stand to gain in the long term.\u201d
Other ACS authors participating in this study include Dr. Emily Marlow, Dr. Marjorie McCullough,
and Dr. Alpa Patel.<\/p>\n\n\n\n
