Why support Teenage Cancer Trust

We create world class cancer services for young people in the UK, providing life-changing care and support so young people don’t have to face cancer alone.

Every day, seven young people aged 13-24 hear the words “you have cancer”. They will each need specialised nursing care and support to get them through the toughest times they may have faced.

We’re the only UK charity dedicated to meeting this vital need. By choosing to run for Teenage Cancer Trust, you can help us to reach every young person facing cancer and make a huge difference.

So you know we’re the real deal, these are our registered charity details: 1062559 (England & Wales), SC039757 (Scotland).
