Malignant mesothelioma is a rare form of cancer that affects the mesothelium — the protective lining that covers the internal organs, such as the lungs, the heart and the abdominal cavity. It is estimated that malignant mesothelioma affects up to 3,200 people in the USA each year, most of whom die within a year of diagnosis. The primary cause of this cancer is exposure to asbestos, which used to be used in building construction…
Cancer Research UK scientists at The University of Manchester found that some melanoma cells are particularly fast growing, but not very good at invading the surrounding tissue, while other melanoma cells are the opposite — highly invasive but slow-growing. …
Professor Geir Hoff and colleagues in Norway, argue that we need more evidence about the malignant potential of benign lesions to be sure that the risks of removing them do not outweigh the benefits of screening. Bowel cancer screening has increased the detection of benign polyps (fleshy growths on the lining of the colon or rectum). The most common polyps found during screening are adenomas and guidelines recommend that they are removed. However, data show that less than 5% of adenomas develop into colorectal cancer, suggesting that 95% of procedures may be exposing patients to unnecessary risks…
