Nearly half of all adult cancer deaths in the US could be prevented by making lifestyle changes, a new study found. Researchers from the American Cancer Society analyzed 18 modifiable risk factors such as smoking, excess body weight, and physical inactivity across 30 types of cancers, and found that they likely contributed to more than half of new cases for 19 cancer types. Most lung cancer cases were linked to smoking — the leading risk factor — with excess body weight being the second biggest contributor to cancer cases. While people can make a “dramatic difference” in their lifestyle by quitting smoking, eating well, and exercising, one doctor told CNN, it’s also crucial that policymakers make it easier for people living in disadvantaged communities to make healthier choices. |
