A grieving mother has paid tribute to her "hero" son, who died of brain cancer after raising hundreds of thousands of dollars for others with the disease.

Harry Moseley, 11, from Sheldon, Birmingham, died on October 8, four years after being diagnosed with a brain tumor.

During his illness he set up the Help Harry Help Others campaign, speaking at events and selling hand-made bracelets to raise more than £500,000 for Cancer Research UK.

"Harry was an inspiration to children and adults alike in his quest to raise awareness of brain cancer," said Richard Taylor, Executive Director of Fundraising at Cancer Research UK. "Harry was a very special boy – even when faced with a life-threatening illness he retained his cheeky persona and his drive to help others. He truly touched the hearts of everyone that he met and the difference he made during his short life is remarkable."

With eyesight problems in 2007, Harry received medical attention and eventually a diagnosis that identified an inoperable brain tumor.

When starting radiotherapy to stop its growth, he met Robert Harley, 55, who was also having radiotherapy treatment for a brain tumor. The two endured the treatment side by side every day for six weeks and became "very good friends".

Sadly, four weeks into the campaign Robert died, having also worn a bracelet from Harry.

You can get involved by ordering a bracelet or donating on the website. Each bracelet costs £2.
