Laser Maps And Zaps Cancer Tumors
7/26/2012
Scientists in the US have developed a laser that can locate, map, and then precisely destroy cancer tumors non-invasively. Using a "femtosecond laser" that pulses at speeds of one-quadrillionth of a second, the new "seek and destroy" device focuses on a specific tissue region to find and precisely map a tumor...
Following Large-scale HPV Vaccination, Human Papillomavirus Types Do Not Replace Others
7/26/2012
Vaccines against human papillomavirus (HPV) are now recommended by the Centers for Disease Control and Prevention for both teenage boys and girls. The vaccine protects against the two most common types of the virus that cause cervical cancer: HPV 16 and 18...
Molecular Link Between Arsenic Exposure And Lung Cancer
7/26/2012
Arsenic is a natural element in the environment, sometimes found in air, soil and water. Arsenic contaminated water is a global threat, currently affecting more than 100 million people. Both genetic and epigenetic changes drive arsenic-induced carcinogenesis and lung cancer is one of the main consequences of this process...
Second-Line Defense Needed For Patients With NSCLC
7/26/2012
In lung cancer, patients who benefit from drugs like erlotinib will inevitably develop drug resistance. This is heralded by cancer growth and increasing tumor-related symptoms. Now scientists are investigating a second line of defense by studying the use of the novel AKT inhibitor MK-2206 in combination with erlotinib for patients whose benefit from erlotinib has begun to wane...
Potential To Improve Human Cancer Studies Using Novel Pig Model
7/26/2012
A naturally occurring line of immunodeficient pigs can support the growth of human tumors injected under their skin, offering a promising new large animal model for studying human cancers and testing new drugs and treatment strategies...
Chronic Obstructive Pulmonary Disease And Increased Risk Of Lung Cancer
7/26/2012
In addition to the well-known risk factor of smoking, chronic obstructive pulmonary disease (COPD) increases lung cancer risk. A University of Colorado Cancer Center study published in the journal Cancer Prevention Research details one novel mechanism of this risk: long-term oxygen depletion stimulates signals that promote tumor growth...

Vaccines against human papillomavirus (HPV) are now recommended by the Centers for Disease Control and Prevention for both teenage boys and girls. The vaccine protects against the two most common types of the virus that cause cervical cancer: HPV 16 and 18...
New Probe Helps Find Cancerous Brain Tumors
7/26/2012
Performing surgery to remove a brain tumor requires surgeons to walk a very fine line. If they leave tumor tissue behind, the tumor is likely to regrow; if they cut out too much normal tissue, they could cause permanent brain damage...
Driver Of Breast Cancer Stem Cell Metastasis Discovered
7/26/2012
Researchers at the University of Michigan Comprehensive Cancer Center have found that a cancer gene linked to aggressive spread of the disease promotes breast cancer stem cells. The finding implies a new way to target the behavior of these lethal cells. The finding involves the cancer gene RhoC, which has previously been shown to promote metastasis of many types of cancer...
Sudden Cardiac Death In Black Athletes May Be Caused By Sickle Cell Trait
7/26/2012
While some published research has hinted at the connection between the sickle cell trait and sudden cardiac death among young, athletic African-American males, which was initially observed in black military recruits 25 years ago, a new study with the first sizeable patient series definitively confirms this risk for these individuals during competitive sports...
