A "Trojan horse" therapy that sneaks toxic drugs inside cancer cells is being made available on the NHS in England in a world first.

It can halt the blood cancer myeloma for nearly three times longer than current therapies.

The drug is an advanced form of chemotherapy that hits cancer with a bigger dose, while reducing side-effects.

Paul Silvester, one of the first people to get it, says the therapy has been "life-changing" and he's now planning history-themed adventures.

Myeloma – also known as multiple myeloma – affects part of the immune system called plasma cells. These are made in the spongey bone marrow in the centre of our bones.
