Dr Chris put her at ease, saying, "No! 'You are happiness and light personified!"
"I wanted more time, I wanted more challenges, I wanted to get to know people better. I wanted to try and win for my charity," Katherine cried, explaining her father died from the disease.
"My dad passed away when I was 13. He had cancer of the colon, and they gave him a few months to live. He went from this big, healthy, strong man to wasting away to skin and bones. To see that as a young child was devastating."
She added, "Nobody knew what to do, and that really shocked me. Since that time, I've always wanted to align myself with an amazing charity that helped people through their cancer."
