In a recent study conducted by the American Cancer Society (ACS), it has been found that as many as 40% of cancer cases and up to half of cancer-related deaths could have been prevented. The study, which focused on 30 types of cancers among adults over age 30, analyzed various modifiable risk factors that contribute to the development and progression of cancer.

According to the findings published in the journal CA: A Cancer Journal for Clinicians on July 11, the biggest contributing risk factor was cigarette smoking. It was responsible for 30% of cancer deaths and nearly 20% of cancer cases. Following this, excess body weight emerged as the second most impactful risk factor, followed by UV radiation and physical inactivity.

Dr. Farhad Islami, senior scientific director of cancer disparity research at the American Cancer Society, commented on the study, stating, "A large number of cancer cases and deaths in the United States are attributable to potentially modifiable risk factors, indicating the potential to substantially reduce the cancer burden through prevention."

Although the findings echoed previous evidence, they underscore the urgent need for a greater emphasis on prevention and early detection of cancer. Dr. Ernest Hawk from The University of Texas MD Anderson Cancer Center emphasized that while treatment is crucial, prevention should be prioritized as the first approach.

The study highlights the importance of personal and societal actions to reduce risks and prevent cancer. Tobacco exposure was identified as the highest risk factor, accounting for approximately 55% of cancers in men and 40% of cancers in women. Dr. Hawk urged for effective support to help smokers break their addiction to nicotine and called for measures to drastically reduce access to vapes, flavored vapes, and nicotine pouches, especially for youth.

Dr. Islami recommended a combination of individual behavioral choices and concerted efforts from public, private, and community organizations at all levels to address the problem. These efforts would include increasing access to preventive healthcare, raising awareness about preventive measures, and implementing known preventive strategies widely.

The study's findings serve as a reminder that there is significant potential to reduce the burden of cancer through preventive measures. By adopting healthier lifestyle behaviors and creating a supportive environment, individuals can minimize their risk of developing cancer.
