Diet, Exercise Reduce Cancer Risk

Call it the worst-kept secret in medicine:  a healthy diet, more exercise and less alcohol lead to “significant reductions in particularly common cancers,” according to the World Cancer Research Fund (WCRF).

The research findings indicate that there would be 38% fewer cases of breast cancer, 45% fewer of colon cancer and 47% fewer of stomach cancer – possibly up to 340,000 fewer U.S. cancer cases each year – if more Americans made these changes.  WCRF officials recommend 150 minutes of moderate physical activity each week, along with quitting smoking and avoiding “excessive sun exposure.”

Researchers may be one step closer to creating a cancer-detecting breath test.

Israeli scientists told BBC News they have created an “electronic nose,” which identified chemical cancer traces in the breath of 80 patients with cancers of the lung, head or neck.  Their findings appear in the British Journal of Cancer.

This is good news, because as lead researcher Professor Hossam Haick of the Israel Institute of Technology said, “diagnosis of the disease is complicated, requiring specialist examinations.”

Dr. Lesley Walker of Cancer Research UK estimates, however, that it will take several more years of research to determine if the test could be used for diagnosis.
