Fluorescent Molecule Helps Pinpoint Cancer Cells

A new fluorescent molecular label has been developed to aid in both the identification and surgical removal of cancer. The molecule, which was created by researchers at the University of California at San Diego (UCSD), works by targeting cancer cells and subsequently tagging them with a fluorescent glow. In addition to fluorescing under near-infrared wavelengths, …

Exposure to Toxic Asbestos – Millions of Veterans Were Affected

Use of asbestos increased significantly during and after the Second World War. This was mainly due to the asbestos manufacturing companies that mass-produced asbestos based products for use on U.S. Navy ships. This led to thousands of sailors and workers getting inadvertently exposed to lethal asbestos dust while cutting and modifying insulation products. Decades later, …

Full-Field Cardiac CT Offers Improved Chance of Incidental Lung Cancer Diagnosis

A retrospective registry of patients undergoing cardiac CT scans suggests that individuals with an increased risk of lung cancer may benefit from a full-field cardiac CT scan. According to researchers at Seoul National University Bundang Hospital, this is because limited-field-of-vision cardiac scans miss 89 percent of the incidental lung cancer findings that could be identified …

Altered Versions of DNA Could Serve as Biomarker for Cancer

In the past few years, new technologies and techniques have become available that allow researchers to quickly sequence large strands of DNA at a fairly affordable cost. Recently, this breakthrough has allowed researchers at Johns Hopkins University to look at DNA mutations as a possible biomarker for cancer. As cancer cells grow and divide, they …
