Blood cancer therapy reverses incurable leukaemia in some patients (www.bbc.com)

A therapy that would once have been considered a feat of science fiction has reversed aggressive and incurable blood cancers in some patients, doctors report.

The treatment involves precisely editing the DNA in white blood cells to transform them into a cancer-fighting "living drug".

The first girl to be treated, whose story we reported in 2022, is still free of the disease and now plans to become a cancer scientist.

Now eight more children and two adults with T-cell acute lymphoblastic leukaemia have been treated, with almost two thirds (64%) of patients in remission.

The revolutionary treatment three years ago involved wiping out her old immune system and growing a new one.

Wow, I'd never have thought something like that was possible.
