A CRISPR gene-editing method could lead to cancer, studies warn

Editing cell genomes with CRISPR-Cas9 might increase the risk of developing cancer, two studies published Monday warn, STAT News reports.

Why it matters: The goal of altering cells with CRISPR, a gene-editing tool, is to treat disease, not cause it. If these new results hold up, they could present an insurmountable roadblock for the development of certain CRISPR-based therapies. They are unlikely to stop all CRISPR-based treatment, however.
