• Cancer deaths linked to obesity in the U.S. have more than tripled from 3.7 to 13.5 deaths per million between 1999 and 2020, with an alarming 19% annual increase from 2018–2020.
• Excess weight significantly raises the risk for 13 common cancers — including colon, breast, liver, pancreatic, kidney, and ovarian — which together make up 40% of all U.S. cancer diagnoses.
• Obesity promotes cancer by causing chronic inflammation, disrupting hormone and insulin balance, and producing chemicals from fat tissue that encourage tumor growth.
• Even modest lifestyle changes — such as losing 5–10% of body weight, improving diet, exercising regularly, managing stress, and getting adequate sleep — can meaningfully reduce cancer risk.
