Over the past few weeks you have been sending in your nominations for the Daily Mirror Pride Of Britain Local Hero Awards 2012, which you can watch exclusively on ITV 1.
The awards recognise the extraordinary achievements of normal people, who make the world a better place.
This week we're bringing you the stories of Wales’ three regional finalists, including Maria Price.
Maria is a nurse at Prince Charles Hospital in Merthyr Tydfil, but sacrifices her days off to raise awareness of bowel cancer.
She has raised enough money to buy a bladder scanner through charity nights, fundraising walks, selling crafts - and even getting others to jump out of planes!
– Maria Price, Local Hero Nominee
I had issues with my bowel when I was younger and I'm actually working on a bowel cancer ward where they're dealing with it on a daily basis. So it has driven me to be able to help other people.
