Cancers of several types are being diagnosed more often in those younger than fifty years of age, and no one really understands why. Because there are consequences to cancer treatment one question is do all these cancers need to be treated? Johns Hopkins Kimmel Cancer Center director William Nelson says that discernment might soon come easier.

Nelson: These young people cancers has animated this discussion but we really need to do is be a little bit better about handicapping when we find a cancer whether it's going to be a bad behaving one or a good behaving one.  And I do have some hope that the genome testing, artificial intelligence approaches will clarify because I do think it's going to be related to what people are now calling multi omics testing. You look at the gene defects, genes that they turn into blueprints for proteins, you look at proteins or modification, you look at the structure of what's going on in the microscope.  :32
