She previously had treatment at the hospital, after being diagnosed with breast cancer in 2015.
She began volunteering at the centre six and a half years ago.
Ms Woodhouse said she was “so pleased” to have completed the abseil.
“It’s been coming on for three months now so just to do it is great,” she said.
“When I was stepping off, I thought we’ve raised so much money this is such a good thing to be doing.”
Ms Turner felt a connection to the centre, having watched her husband, two of her sisters and her daughter go through cancer.
After completing the challenge, she said: “It’s a very slippy surface, it was quite difficult to keep your feet in contact with the wall.”
“It’s all for a fantastic reason that we’ve done it,” she added.
