Clinical researchers at Princess Margaret Hospital (PMH) have confirmed that patients with oropharyngeal squamous cell cancer ("tonsil cancer") harbour a common type of human papilloma virus (HPV16), but also that such cancers are very sensitive to radiation. For some patients, this may mean successful treatment with radiation alone and avoiding the side effects of chemotherapy. http://www.physorg.com/news176472331.html Medicine & Health Tue, 03 Nov 2009 12:50:01 EST news176472331 Public speaking, anyone? Or maybe a big job interview? Dry your palms and take a deep, calming breath; there may be a silver lining. Researchers at the Stanford University School of Medicine have shown that, at least in laboratory mice, bouts of relatively short-term stress can boost the immune system and protect against one type of cancer. Furthermore, the beneficial effects of this occasional angst seem to last for weeks after the stressful situation has ended. The finding is surprising because chronic stress has the opposite effect -- taxing the immune system and increasing susceptibility to disease. http://www.physorg.com/news172762386.html Medicine & Health Mon, 21 Sep 2009 15:50:01 EST news172762386 Chronic periodontitis, a form of gum disease, is an independent risk factor for head and neck squamous cell carcinoma. This suggests the need for increased efforts to prevent and treat periodontitis as a possible means to reduce the risk of this form of cancer. http://www.physorg.com/news171609518.html Medicine & Health Tue, 08 Sep 2009 07:20:01 EST news171609518 Researchers continue to add to the diagnostic alphabet of saliva by identifying the presence of at least 50 microRNAs that could aid in the detection of oral cancer, according to a report in Clinical Cancer Research, a journal of the American Association for Cancer Research. http://www.physorg.com/news170427545.html Medicine & Health Tue, 25 Aug 2009 13:59:27 EST news170427545 A virus discovered last year in a rare form of skin cancer has also been found in people with the second most common form of skin cancer among Americans, according to researchers at the Ohio State University Comprehensive Cancer Center - James Cancer Hospital and Solove Research Institute. http://www.physorg.com/news168180173.html Medicine & Health Thu, 30 Jul 2009 13:44:34 EST news168180173 Researchers at the University of Maryland Marlene and Stewart Greenebaum Cancer have found that head and neck cancer patients who test positive for the human papillomavirus (HPV) have much better survival rates than patients who don't have the virus, according to a new study in the journal Cancer Prevention Research. The researchers also discovered that blacks in the study had a very low rate of HPV infection, and consequently worse survival, which may explain why African-American patients traditionally have had a poor prognosis for head and neck cancer. http://www.physorg.com/news168095606.html Medicine & Health Wed, 29 Jul 2009 14:50:02 EST news168095606 As a specialist in skin disorders and cancers, Dr. Janellen Smith sees firsthand what too much sun can do.
