New at-risk group identified for gastrointestinal stromal tumors

Medicine & Technology Oct 08, 2014

Researchers at the University of California, San Diego School of Medicine have, for the first time, clearly defined the epidemiology of gastrointestinal stromal tumors (GIST), which occur primarily in the lining of the stomach and small intestine. One key finding: Patients of Asian descent, who have not previously been identified as an at-risk population, are 1.5 times more likely than other patient groups to be diagnosed with this type of tumor. Results of the study were published this week in Cancer Epidemiology, Biomarkers & Prevention, a journal of the American Association for Cancer Research.

The Skin Cancer Selfie

Oct 07, 2014

Melanoma is the fifth most common cancer type in the United States, and it's also the deadliest form of skin cancer, causing more than 75 percent of skin-cancer deaths. If caught early enough though, it is almost always curable. Now a camera, capable of taking snapshots of the entire human body and rendering high-resolution images of a patient's skin may help doctors spot cancer early and save lives.
