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. One patient with the most common type of pediatric brain cancer, medulloblastoma, also showed tumor shrinkage. http://www.physorg.com/news171135993.html Medicine & Health Wed, 02 Sep 2009 18:47:19 EST news171135993 UCSF scientists have discovered that a tiny filament extending from cells, until recently regarded as a remnant of evolution, may play a role in the most common malignant brain tumor in children. http://www.physorg.com/news170255032.html Medicine & Health Sun, 23 Aug 2009 14:04:37 EST news170255032 Tiny, solitary spikes that stick out of nearly every cell in the body play a central role in a type of skin cancer, new research has found. 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 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. Sunburns and accelerated skin aging are common results, but excessive sun exposure also can be deadly. http://www.physorg.com/news165513473.html Medicine & Health Mon, 29 Jun 2009 22:00:02 EST news165513473 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 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. The findings, presented at the 236th meeting of the American Chemical Society, may open doors to development of new methods to detect basal cell carcinoma and other forms of skin cancer. http://www.physorg.com/news138469302.html Medicine & Health Wed, 20 Aug 2008 16:41:42 EST news138469302
