From UC SAN DIEGO: April 2009 - In a new study, researchers at the Moores Cancer Center and Department of Family and Preventive Medicine, UC San Diego used a complex computer prediction model to determine that intake of vitamin D3 and calcium would prevent 58,000 new cases of breast cancer and 49,000 new cases of colorectal cancer annually in the US and Canada.
