Advances in the genomic era have led to identification of cancer-causing genes and unprecedented progress in the development of gene-targeted therapies and agents that can unleash the immune system. These advances have improved the outlook for patients with lethal malignancies.Cancer is a genomic disease in that gene alterations drive the cellular growth and immune surveillance perturbations that enable malignant cells to take hold and to metastasize. Hereditary genetic factors play a key role in cancer predisposition, initiation, prognosis, and therapy. In a previous viewpoint, we posited that we need universal (somatic) genomic testing to win the war against cancer. 1 Currently, given the rapidly emerging evidence, we update our view to state that universal germline, in addition to tumor somatic, genomic testing is needed to win the war against cancer. 1 Author affiliations and support information (if applicable) appear at the end of this article.
