Health Highlight: Researchers use gut bacteria to map genetic mutations in colorectal cancer tumours

Gut bacteria

Colorectal cancer is now understood to be definitely linked to microbial problems in the gut. Research has shown that the disease is linked with less numbers and diversity in the gut microbiome, and with the increased presence of more harmful strains. Therefore using gut bacteria to diagnose and even aid in cancer prevention is highly desirable due to it’s quick, non-invasive ease of investigation.

Now, a study from researchers at University of Minnesota has predicted key genetic mutations in colorectal tumours by analyzing the types of gut bacteria present around them. The team state that it could be possible to genetically classify the colorectal tumour a person has without having to do a biopsy and dissect it. Their findings were presented at the American Society of Human Genetics (ASHG) 2015 Annual Meeting.

No Convincing Evidence that Cell Phones Cause Cancer

A new report by the U.K. Health Protection Agency’s independent Advisory Group on Non-ionising Radiation (AGNIR) has concluded that there is no convincing evidence that mobile phone technologies cause adverse effects on human health. The report updates AGNIR’s previous review in 2003 that considers the scientific evidence on exposure to radiofrequency (RF) electromagnetic fields, which are produced by mobile phone technologies and other wireless devices, such as Wi-Fi, as well as television and radio transmitters.

Biomarker Bulletin: January 30, 2012

Biomarker Bulletin is an occasionally recurring update of news focused on biomarkers aggregated at BiomarkerCommons.org. Biomarkers are physical, functional or biochemical indicators of normal physiological or disease processes. The individualization of disease management — personalized medicine — is dependent on developing biomarkers that promote specific clinical domains, including early detection, risk, diagnosis, prognosis and predicted response to therapy.
