Many cancer therapies target specific proteins that proliferate on the outside of some cancer cells, but the therapies are imperfect and the cancer does not always respond. Since it is beneficial for doctors to know as soon as possible how a cancer is affected by treatment, researchers from Vanderbilt University are striving to design tests that assess treatment response rapidly, accurately, and cost-effectively. The team has demonstrated a new way to optically test cultured cancer cells' response to a particular cancer drug. The results appear in the December issue of the Optical Society's (OSA) open-access journal Biomedical Optics Express. http://phys.org/news243608831.html Physics Tue, 20 Dec 2011 13:07:28 EST news243608831 Using ovarian surface epithelial cells from mice, researchers from Virginia Tech have released findings from a study that they believe will help in cancer risk assessment, cancer diagnosis, and treatment efficiency in a technical journal: Nanomedicine. http://phys.org/news229104683.html Nanotechnology Tue, 05 Jul 2011 17:11:41 EST news229104683 Older men with high-risk prostate cancer frequently are offered fewer – and less effective – choices of treatment than younger men, potentially resulting in earlier deaths, according to a new UCSF study. http://phys.org/news212170358.html Medicine & Health Tue, 21 Dec 2010 16:13:04 EST news212170358
