Liquid Biopsies Can Guide Cancer Treatment

Health Editor’s Note: Liquid biopsies analyze DNA that tumors have shed into the blood stream. Up till now, a biopsy takes a sample of the tumor and is far more invasive and usually quicker. Immunotherapies and targeted therapies work against tumors that have genetic changes and after analyzing the genetic changes: tumor profiling,  genomic profiling, or tumor sequencing a specific therapy can be chosen. These liquid biopsies, from two different companies are used for solid tumors, not cancers of the blood. These biopsies are the first blood tests to be approved that look for multiple cancer-related changes, not just one, as previously approved blood tests did….Carol
