A new UCSF study has found a clear association between certain genes and the development of lymphedema, a painful and chronic condition that often occurs after breast cancer surgery and some other cancer treatments. http://medicalxpress.com/news/2013-04-genetic-markers-linked-lymphedema-breast.html Cancer Tue, 16 Apr 2013 17:26:13 EST news285351966 One of the greatest challenges faced by cancer surgeons is to know exactly which tissue to remove, or not, while the patient is under anesthesia. A team of surgeons and scientists at University of California, San Diego School of Medicine have developed a new technique that will allow surgeons to identify during surgery which lymph nodes are cancerous so that healthy tissue can be saved. The findings will be published in the January 15 print edition of Cancer Research. http://medicalxpress.com/news/2013-01-surgical-technique-cancer-invasion-fluorescence.html Cancer Thu, 10 Jan 2013 14:38:00 EST news277051074 Australian scientists have confirmed a 'weak link' in the immune system – identifying the exact conditions under which an infection can trigger an autoantibody response, a process not clearly understood until now. http://medicalxpress.com/news/2012-11-infection-trigger-autoimmune-disease.html Immunology Fri, 09 Nov 2012 10:01:04 EST news271677651 A previously unrecognized system that drains waste from the brain at a rapid clip has been discovered by neuroscientists at the University of Rochester Medical Center.
