13-year-old boy meets bone marrow donor who saved his life

This is the emotional moment a teenage cancer survivor met the stem cell donor who saved his life three years ago - when the lad was given just six months to live. Jack Withers was just ten when he was diagnosed with a form of blood cancer in 2015 - five years after his twin sister Emily fought the disease. Without a donor, doctors said he had just six months to live, and a worldwide search was launched. The schoolboy from from Walsall was matched with blood stem cell donor, Michael Mertens, 30, from Germany, thanks for charity DKMS.
