jan 1, 2014 - Analyzing DNA in Cancer

Description:

Researchers from The Cancer Genome Atlas (TCGA) project, a joint effort by NCI and the National Human Genome Research Institute to analyze the DNA and other molecular changes in more than 30 types of human cancer, find that gastric (stomach) cancer is actually four different diseases, not just one, based on differing tumor characteristics. This finding from TCGA and other related projects may potentially lead to a new classification system for cancer, in which cancers are classified by their molecular abnormalities as well as their organ or tissue site of origin.
