When you have been diagnosed with cancer, there are things you sometimes can't say to the people you love.
You don't want to upset them, or let them see how frightened you really are. For many people across Wales, Karen is the person they can say it to.
After more than 20 years as a district nurse, caring for people with cancer in their own homes, Karen now takes calls on our free Support Line. She makes at least 10 scheduled calls a day, on top of every call that comes in, and here she tells us why she does it.
Over 20 years of caring for people at home
Karen's career began in district nursing, where she spent more than two decades looking after people who had been diagnosed with cancer and were undergoing treatment. She helped patients manage their side effects, cared for PICC lines and offered emotional support, as well as advice and reassurance to their families whenever it was needed.
She also cared for people at the end of their lives, making sure they were comfortable, free from pain and treated with dignity at all times.
Why Karen joined the Support Line
After so many years supporting people with cancer, Karen wanted to carry on making a difference to people who have received a diagnosis. She knows from experience that talking to the people closest to you isn't always easy.
