Cliffs:
A woman with cancer had survived 9 years, but in 2018, it was found spreading through her lungs and chest, and she was considered terminal.
She accepted an experimental treatment where she was injected with T-cells which were specifically engineered to seek and destroy cancer cells.
The cancer was completely eradicated, from what they can tell.
However, this therapy (known as CAR-T therapy) is new and just being tested, and it has found only to work for some people.
