Once or twice a week, Dawn Malcolm can be found in the University College Hospital Macmillan Cancer Centre checking in patients for their appointments, giving them directions to wards and offering a listening ear.

She also brings in magazines and does jigsaws with patients who are having chemotherapy.

Dawn said: “My aim is to reduce anxiety and to let in a little bit of light. Even if it’s just doing a jigsaw with someone, it helps takes their mind off what they are going through.

“You are just a small cog in a big wheel but it takes lot of small parts to make that wheel go round.

“Volunteering is one of the best things I have ever done. It has given me such purpose and joy.”
