Many heart transplant patients develop multiple skin cancers, with increased risk for some skin cancers among patients with other cancers and with increasing age, according to a report in the December issue of Archives of Dermatology. http://www.physorg.com/news180638833.html Medicine & Health Mon, 21 Dec 2009 18:20:04 EST news180638833 (PhysOrg.com) -- Scientists at the University of Pennsylvania School of Medicine have developed a new model of skin cancer based on the knowledge that a common cancer-related molecule called Src kinase is activated in human skin-cancer samples. http://www.physorg.com/news179597186.html Medicine & Health Wed, 09 Dec 2009 16:20:01 EST news179597186 Joan Ketterer still recalls the button her son Edward got for donating his baby teeth to what was then a ground-breaking study looking at the effect of nuclear fallout on children born in the St. Louis-area in the 1960s. http://www.physorg.com/news175368568.html Medicine & Health Wed, 21 Oct 2009 18:30:55 EST news175368568 A new study resolves a 130-year-old mystery over the developmental origin of specialized skin cells involved in touch sensation. The findings will appear in the October 5, 2009 issue of the Journal of Cell Biology. http://www.physorg.com/news173354601.html Biology Mon, 28 Sep 2009 11:20:03 EST news173354601 The Merkel cell polyomavirus (MCPyV) is the only human polyomavirus known to be associated with a rare skin cancer, known as Merkel cell carcinoma, according to a new study published online September 23 in the Journal of the National Cancer Institute. http://www.physorg.com/news172944590.html Medicine & Health Wed, 23 Sep 2009 17:12:12 EST news172944590 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 The Hedgehog signaling pathway is involved in a preliminary study and case report describing positive responses to an experimental anticancer drug in a majority of people with advanced or metastatic basal cell skin cancers.

The discovery in mice shows that the microscopic structures known as primary cilia can either suppress or promote this skin cancer, depending on the mutation triggering the disease. http://www.physorg.com/news170254493.html Medicine & Health Sun, 23 Aug 2009 13:56:06 EST news170254493 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 Cancerous tumors sometimes form at the site of chronic wounds or injury, but the reason why is not entirely clear. Now researchers at Washington University School of Medicine in St. Louis have engineered mice with a persistent wound-like skin condition, and the mice are helping them understand the tumor-promoting effects of long-standing wounds and injuries. http://www.physorg.com/news166104028.html Medicine & Health Mon, 06 Jul 2009 13:30:02 EST news166104028 As a specialist in skin disorders and cancers, Dr. Janellen Smith sees firsthand what too much sun can do.

The skin patch, which delivers the radioactive phosphorus-32, is nontoxic and could be an excellent alternative to surgery or radiotherapy in cases where carrying out these treatments is difficult. http://www.physorg.com/news164289550.html Medicine & Health Mon, 15 Jun 2009 12:59:30 EST news164289550 Actinic keratoses are sun-damaged rough patches or lesions on the skin - often pink and scaly - that doctors have long believed can turn into a form of skin cancer known as squamous cell carcinoma. http://www.physorg.com/news163181200.html Medicine & Health Tue, 02 Jun 2009 17:10:12 EST news163181200 Fox Chase Cancer Center investigators report that a two-drug blockade of mTOR signaling appears safe in metastatic kidney cancer in a phase I trial.

We report a patient with adenocarcinoma of the stomach combined with choriocarcinoma and neuroendocrine cell carcinoma. This is the first reported case of gastric cancer with these three pathological features. http://www.physorg.com/news140953665.html Medicine & Health Thu, 18 Sep 2008 10:47:45 EST news140953665 According to new research from the Monell Center, odors from skin can be used to identify basal cell carcinoma, the most common form of skin cancer.
