Around 40% of Americans develop cancer. Fortunately, there's a lot you can do to reduce your risk.

Some smart moves seem obvious: Wear sunscreen daily; don't smoke or hang around people who do; don't drink too much (or any) alcohol; avoid red meats and foods laced with toxins, preservatives, and sugars.

But here are some equally powerful, lesser-known ways to reduce your risk:

• Become a healthy vegetarian. A study in BJC (the British Journal of Cancer) found that vegetarians have a 28% lower risk of kidney cancer, a 31% lower risk of multiple myeloma, 21% lower risk of pancreatic cancer, 12% lower risk of prostate cancer, and 9% lower risk of breast cancer than meat eaters. If you’re not comfortable becoming a vegetarian, stick with fish such as salmon and occasionally have skinless poultry — along with lots of fresh produce.

• Achieve a healthy weight. Up to 8% of cancers — including breast, colorectal, esophageal, kidney, gallbladder, uterine, pancreatic, and liver — are attributable to obesity. Consider a GLP-1 if you need help getting to a healthy waist size.

• Get vaccinated (or get your kids vaccinated ) for HPV. The human papillomavirus causes most cases of cervical cancer, and can cause cancers of the vagina, penis, anus, mouth, and throat. Girls can get vaccinated from ages 9 to 26; boys from ages 9 to 21.

• Get vaccinated against Hepatitis B. This infection is associated with 70% to 80 % of cases of liver cancer.

In addition to those measures, you should get recommended screenings for prostate, breast, gynecological, skin, and oral cancers.
