Dr. Amar Rewari Featured in Prevention: Everyday Lifestyle Changes to Lower Your Cancer Risk

Dr. Amar Rewari was featured in a recent article exploring a major study published in Nature Medicine that found up to four in 10 cancer cases worldwide may be preventable through lifestyle changes.

In the piece, Dr. Rewari provided expert commentary on the study's identification of eight key risk factors — including tobacco use, alcohol consumption, obesity, physical inactivity, and infection — and what they mean for everyday people. He emphasized that the findings challenge a common misconception: that cancer is largely driven by genetics or luck. "Nearly 40% of cancers globally are linked to factors we already understand and, at least in theory, can change," he explained.

Dr. Rewari also highlighted how prevention strategies need to be tailored by region, noting that lifestyle factors like smoking and obesity drive more cases in higher-income countries, while infection-related cancers remain a major concern in lower-resource settings.

His key advice: avoid tobacco in all forms, limit alcohol, stay active, maintain a healthy weight, and stay current on vaccinations like HPV and hepatitis B — which he describes as "powerful cancer-prevention tools, not just infection-prevention tools."
