Risky Experimental Cancer Therapy Shows Promise For Blood Cancers

There's increasing excitement in the world of cancer research regarding the potential of immunotherapy — treatments that use a patient's own immune system to fight cancer.

One promising experimental therapy, particularly for blood cancers, is called CAR-T cell therapy. It's very risky, and brutal on the body. But when it works, it's been shown make cancers disappear entirely.

Here & Now's Meghna Chakrabarti talks with Meghana Keshavan, biotech correspondent at the health and medicine publication STAT, about how CAR-T works, and how close it is to moving out of the experimental phase and into the mainstream.
