A new study finds that in sharp contrast to the overall declining rates of colorectal cancer in the United States, incidence rates among adults younger than age 50 years are increasing. The authors theorize that these increases may be related to rising rates of obesity and changes in dietary patterns, including increased consumption of fast food. The study, which appears in the June 2009 issue of Cancer Epidemiology Biomarkers and Prevention, says further studies are necessary to elucidate causes for this trend and to identify potential prevention and early detection strategies. http://www.physorg.com/news163644954.html Medicine & Health Mon, 08 Jun 2009 01:56:30 EST news163644954 A new study examining data on incidence trends, mortality rates and survival rates from the National Cancer Institute's Surveillance Epidemiology and End Results (SEER) cancer registries indicates that the incidence of liver cancer in the United States tripled between 1975 and 2005. http://www.physorg.com/news154191005.html Medicine & Health Wed, 18 Feb 2009 14:50:45 EST news154191005 Women who took beta carotene or vitamin C or E or a combination of the supplements had a similar risk of cancer as women who did not take the supplements, according to data from a randomized controlled trial in the December 30 online issue of the Journal of the National Cancer Institute. http://www.physorg.com/news149924804.html Medicine & Health Wed, 31 Dec 2008 05:46:44 EST news149924804 Taking calcium and vitamin D supplements does not reduce breast cancer incidence in postmenopausal women, according to data from a randomized, doubled-blind, placebo-controlled trial published online November 11 in the Journal of the National Cancer Institute. http://www.physorg.com/news145644927.html Medicine & Health Tue, 11 Nov 2008 16:55:27 EST news145644927 Cancer incidence is higher among liver transplant recipients in Finland compared to the general population, according to a new study in the October issue of Liver Transplantation. http://www.physorg.com/news142166426.html Medicine & Health Thu, 02 Oct 2008 11:40:26 EST news142166426
