One of the most common responses when I tell people the most important things they can do to prevent cancer, based on the scientific evidence, is that the things seem so simple or obvious.
Maintain a healthy weight. Be physically active. Use sunscreen and sun protective clothing when you can’t choose to be in the shade. Practice safe sex to avoid sexually transmitted infections. Eat a diet rich in fruits, vegetables and whole grains. Choose to spend time in places free of secondhand smoke. Quit smoking if you smoke.
They do sound like health tips. They aren’t sexy or “hot” or “new” like it would be to talk about plastics, pesticides, lotions and the like. But here’s the thing… while we still have plenty of work to do to explore the role those factors might play in cancer, we KNOW that the things above matter. We know that if we implemented those things and a few others, we could prevent at least HALF of all cancers. Continue reading
We all know by now that the best way to prevent lung cancer is to not smoke or use any tobacco products. But about ten to fifteen percent of nonsmokers still get lung cancer, a disease that accounts for more deaths than any other cancer type.
For nonsmokers, eating high amounts of tofu, edamame and other soy foods may lower their risk, finds a new study along with an analysis of the research.
The study was published in the American Journal of Epidemiology.
Study researchers first looked at the diet of approximately 71,000 women who were part of a health study in China. Almost all the women – 97 percent – didn’t smoke. The women answered questions about their typical diet at the start of the study and again two to three years later. They also gave information on their exposure to secondhand smoke and medical history.
After an average of nine years, the study found that women who consumed the most soy foods had almost 40 percent lower risk of lung cancer compared with those who ate the least amounts. This was after taking into account age, other dietary factors and smoking. (Of the 370 women diagnosed with lung cancer during those nine years, all but 30 had never previously smoked.)
