Sarah Smith (left) has raised over £4,600 for AMMF, a charity aiming to raise awareness of cholangiocarcinoma (bile duct cancer), by climbing Mount Kilimanjaro, in support of colleague Kathryn Swain (right). Kathryn worked as an associate dentist in Macclesfield for 25 years and in March 2013 was diagnosed out of the blue with cholangiocarcinoma. Sarah originally joined Kathryn's practice as a trainee dental nurse and later left to train as a dental therapist. Wanting to do something positive to support long-time friend and colleague Kathryn, she decided to climb Kili, paying all her own expenses, and has been sponsored by patients, colleagues and friends well beyond her target of £2,500.
