NEW YORK, July 15: A comprehensive study conducted by the American Cancer Society (ACS) has uncovered that nearly half of cancer-related deaths among US adults over 30 years old could be attributed to modifiable risk factors. Analyzing data from 1.78 million cases in 2019, researchers highlighted key lifestyle choices that significantly impact cancer outcomes.

The study emphasizes the critical role of individual decisions in reducing cancer incidence and mortality. By addressing factors such as cigarette smoking, lack of exercise, and excess body weight, individuals can potentially mitigate their risk of developing and succumbing to various forms of cancer.

"Large numbers of cancer cases and deaths in the United States are attributable to potentially modifiable risk factors," noted the researchers in their published findings. This underscores the potential for substantial reductions in the cancer burden through widespread adoption of preventive initiatives and improved healthcare accessibility.

Among the 30 types of cancer studied, more than half of the cases and deaths were associated with preventable factors. Smoking emerged as the most significant contributor, accounting for 19.3% of overall cases, followed by excess body weight at 7.6%, alcohol consumption at 5.4%, UV radiation exposure at 4.6%, and physical inactivity at 3.1%.

The study highlighted cervical cancer, where 100% of cases could theoretically be prevented through vaccination against cancer-related viruses like hepatitis B. Lung cancer topped the list in terms of cases linked to modifiable risk factors, with 104,410 cases in men and 97,250 cases in women in 2019 alone.

Dr. Farhad Islami, a cancer epidemiologist at ACS, stressed the importance of robust tobacco control policies to promote smoking cessation and increase early detection efforts for lung cancer. "Interventions aimed at maintaining a healthy body weight and diet can also significantly reduce cancer incidence and mortality rates in the country," Islami added.

While genetic and environmental factors play roles in cancer development, lifestyle choices remain pivotal. The disease involves uncontrolled cell division leading to abnormal growths that can severely damage organs and disrupt biological functions.

Despite advancements in treatment and improving recovery rates, the study serves as a stark reminder of the potential for cancer prevention through lifestyle changes—such as smoking cessation, weight management, sun protection practices, and moderation in alcohol consumption.

Ahmedin Jemal, another cancer epidemiologist at ACS, emphasized the need for equitable access to preventive healthcare and increased awareness of preventive measures. "These findings underscore the ongoing imperative to expand access to preventive healthcare services and educate the public about effective preventive measures," Jemal concluded.

This study underscores the significant impact of lifestyle choices on cancer outcomes and advocates for proactive measures to reduce the burden of preventable cancers across the United States.
