Investigating A Causal Link Between Gut Bacteria and Breast Cancer

In that the human body contains billions of microorganisms, and microbial cells found in the human gut are estimated to outnumber human cells by ten-to-one in healthy adults, Ece Mutlu, from Rush University Medical Center (Illinois, USA), and colleagues have embarked on a research study, funded by the U.S. Department of Defense, to chart the presence of microorganisms found within the gut and to explore how microbial imbalances may impact diseases like breast cancer.  While about 20 to 25% of the risk of developing breast cancer is related to family history, the known breast cancer susceptibility genes such as BRCA2 and BRCA 2 explain less than 5-10% of the total breast cancer cases attributable to familial factors.  Researchers are thus exploring the possibility that the gut microbiome passed on from mother to child may be another familial factor previously never accounted for in the genetic risk models.  Explains Dr. Mutlu:  “The currently recognized environmental risk factors are estimated to account for only 40 % of the variance in breast cancer incidence.  There is a large body of evidence implicating that dietary factors such as alcohol, high fat foods are also possible breast cancer risk enhancers, and fruits and vegetables are protective.  If we are able to find the microbes responsible for particular diseases, it may increase the likelihood of developing new diagnostic tests and treatments for diseases like breast cancer.”

VIDEO: Brain Age Workshop
Dr. Eric Braverman, Director of The Place for Achieving Total Health (PATH Medical), Chairs the Brain Age Workshop taking place Dec. 9, 2009. Held in conjunction with the Winter Session of the 17th Annual World Congress on Anti-Aging Medicine & Regenerative Biomedical Technologies. The Brain Age Workshop features presentations on Brain Mind Assessment via Neuropsychological Analysis, Movement Deficiency Syndrome, Hormones and the Brain, Nootropic Drug Mechanisms, and Traumatic Brain Injury. View this video to learn about Dr. Braverman’s brain-based model of aging and age modulation.
