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 Scientists funded by the Biotechnology and Biological Sciences Research Council (BBSRC) have discovered why older people may be so vulnerable to cancer and infections in the skin. The team from UCL has shown in human volunteers that defective immunity in the skin is caused by an inability to mobilise essential defences that would otherwise recognise threats and clear them before irreparable damage is done. This discovery could be important for preventing, managing or treating many age-related skin health problems. The study will be published in 31 August edition of the Journal of Experimental Medicine. http://www.physorg.com/news170659774.html Medicine & Health Fri, 28 Aug 2009 06:40:01 EST news170659774 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 Slather on some SPF 30 sunscreen and you know your nose won't turn pink. http://www.physorg.com/news170083379.html Medicine & Health Fri, 21 Aug 2009 20:30:01 EST news170083379 Most melanomas detected in a general-practice dermatology clinic were found by dermatologists during full-body skin examinations of patients who had come to the clinic for different complaints, according to a report in the August issue of Archives of Dermatology. In addition, cancers detected by dermatologists were thinner and more likely to be in situ (only on the outer layer of skin) than were cancers detected by patients. http://www.physorg.com/news169750632.html Medicine & Health Mon, 17 Aug 2009 18:10:01 EST news169750632 UT Southwestern Medical Center researchers are studying a new antigen to see whether it can track down and kill cancer cells in patients with recurring melanoma, the leading cause of skin cancer deaths. http://www.physorg.com/news169124584.html Medicine & Health Mon, 10 Aug 2009 12:03:28 EST news169124584 Recent research has uncovered an unexpected vulnerability in deadly melanoma cells that, when exploited, can cause the cancer cells to turn against themselves. The study, published by Cell Press in the August issue of the journal Cancer Cell, identifies a new target for development of future therapeutics aimed at selectively eliminating this aggressive skin cancer which is characterized by a notoriously high rate of metastasis and treatment-resistance. http://www.physorg.com/news168523563.html Medicine & Health Mon, 03 Aug 2009 13:06:23 EST news168523563 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 (AP) -- International cancer experts have moved tanning beds and ultraviolet radiation into the top cancer risk category, deeming both to be as deadly as arsenic and mustard gas. For years, scientists have described tanning beds and ultraviolet radiation as "probable carcinogens." http://www.physorg.com/news168026838.html Medicine & Health Tue, 28 Jul 2009 19:08:51 EST news168026838 Scientists from the Queensland Institute of Medical Research (QIMR) have found two new genes that together double a person's risk of developing melanoma. http://www.physorg.com/news166098212.html Medicine & Health Mon, 06 Jul 2009 11:23:56 EST news166098212 Researchers at the Moores UCSD Cancer Center are injecting a modified herpes virus into melanoma tumors, hoping to kill the cancer cells while also bolstering the body's immune defenses against the disease. http://www.physorg.com/news165687558.html Medicine & Health Wed, 01 Jul 2009 17:20:27 EST news165687558 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 How important is it for my child to wear sunglasses? http://www.physorg.com/news163273176.html Medicine & Health Wed, 03 Jun 2009 18:40:36 EST news163273176 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 You know the guy -- he's your Facebook friend. The one who knows everyone. Secure at the center of a dense web of relationships, he suggests causes and reconnects old friends like a skilled matchmaker. Scientists have known for some time that biological molecules interact with one another in a similarly complex pattern. Now researchers at the Stanford University School of Medicine have determined that hamstringing these molecular powerbrokers is a good way to derail processes such as cancer development. http://www.physorg.com/news163078173.html Medicine & Health Mon, 01 Jun 2009 12:30:11 EST news163078173 (AP) -- New research finds that people who had radiation treatments for cancer as children are less likely than the general public or even their healthy siblings to get recommended screening tests. http://www.physorg.com/news163072496.html Medicine & Health Mon, 01 Jun 2009 10:55:34 EST news163072496 Now that the weather is nice, people will spend more time outside. Whether it`s doing yard work, playing golf or relaxing at the beach, we are a nation of sun lovers. Some people with light skin may even spend a few sessions in the tanning booth to begin to develop a golden hue that looks like they spent a week at the beach. Others work outside and whether they planned to or not, they will get more sunlight for the next six months. This carries a note of concern, since sunlight is very likely the reason malignant melanoma incidence has doubled since the 1970`s with an estimated 69,000 new cases expected this year and almost 9,000 deaths. http://www.physorg.com/news162666086.html Medicine & Health Wed, 27 May 2009 18:02:26 EST news162666086 (PhysOrg.com) -- Dendritic cells are the sentinels of the immune system. When they`re alert and on guard, they will marshal the body`s immunosoldiers, T cells, to battle at the sight of harmful pathogens. But some diseases, such as cancer, are able to escape their watchful eye. By knocking out or beguiling dendritic cells, they slip the defenses of the immune system and sack the unsuspecting body. New research shows that one of the most common types of skin cancer has learned such a trick, finding a way to disable apparently healthy dendritic cells, which then allow cancer cell nests to spread around them without calling T cells to the fight. http://www.physorg.com/news162658919.html Medicine & Health Wed, 27 May 2009 16:02:46 EST news162658919 (PhysOrg.com) -- Cheap, convenient and casual, baseball caps and flip-flops have acquired a trendy charm.

These findings appear in the April 2009 issue of the Journal of the Dermatology Nurses' Association. http://www.physorg.com/news159685661.html Medicine & Health Thu, 23 Apr 2009 06:08:16 EST news159685661 Older men whose melanoma is detected by a physician are more likely to have thinner and therefore more treatable tumors at diagnosis, according to results of a survey published in the April issue of Archives of Dermatology, one of the JAMA/Archives journals.
