Hidden benefit of age: Decreased risk of surgical infection

Contrary to what you might think, advanced age does not increase the risk of surgical-site infections, according to a large long-term study reported in the 1 April issue of The Journal of Infectious Diseases, now available online. more  

MR spectroscopy: A better way to determine prostate cancer prognosis

A new way of evaluating prostate tumors may help physicians determine the best treatment strategy. Using magnetic resonance (MR) spectroscopy, which provides detailed information on the chemical composition of tissue samples, researchers from Massachusetts General Hospital (MGH) have shown that chemical profiles of prostate tissue can determine a tumor's prognosis better than standard pathological studies do. The report appears in the 15 April issue of Cancer Research. more

New treatment for hereditary breast cancer 

Researchers at Stockholm University have, together with colleagues in England, discovered a new way of treating and preventing hereditary breast cancer. The article, published in Nature, describes how the use of a chemical inhibitor can specifically kill tumour cells, which have a defect in the gene causing hereditary breast cancer. This new treatment targets only the tumour cells and is not likely to affect other healthy cells in the body. The discovery could also lead to a prophylactic treatment for hereditary breast cancer. more

Fat is a big contributor to breast tumor growth 

Increased adipose mass is associated with an elevated risk of breast cancer, but little was known about how fat cells actually contribute to carcinogenesis. In a study appearing online on 14 April in advance of the print publication of the May issue of the Journal of Clinical Investigation, Philipp Scherer and others aimed to identify factors that are secreted by adipocytes and which are present in breast cancer stromal tissue. more

Stroke diagnosis: Test women too!

Women who have strokes are less likely to receive some standard tests to help diagnose the type of stroke and determine treatment. more
