"Nearly Half of Cancer Cases Preventable with Lifestyle Changes"

A new American Cancer Society study suggests that about 40% of cancer cases and nearly half of all cancer deaths in the U.S. are linked to avoidable risk factors such as smoking, excess weight, and physical inactivity. Cigarette smoking is the leading risk factor, contributing to nearly 20% of all cancer cases and 30% of cancer deaths. The study highlights the importance of interventions to maintain a healthy body weight and diet to reduce cancer incidence and mortality.
