Summary

This study follows over 96,000 Seventh-day Adventists in the U.S. and Canada to see how diet and lifestyle choices relate to breast, colorectal, and prostate cancer. Researchers are focusing on intakes of meat, soy, and dairy. Because it is observational, it can show patterns but cannot prove cause and effect.
