Cancer Hospitals Make Gene Tests a New Standard for Care

Pinpointing the genetic changes that cause cancer has been a focus of researchers for more than a decade. Now, top cancer hospitals are making genetic testing a new standard of care in the field.

When patients leave Memorial Sloan Kettering Cancer Center in New York after a biopsy, a sample of their tumor takes a different path. It travels across the street to a new laboratory, opened last month, where it will be tested for 341 genetic mutations, so-called biomarkers that will help doctors determine which drug may best help each patient, based more on their genetic profile than where the tumor appears.
