Tierney Kinsella, 18, was diagnosed with osteosarcoma, an aggressive and rare form of bone cancer, in 2015. She joins Deborah James, Lauren Mahon and Steve Bland to talk about her experiences since being told in September 2018 that her cancer was inoperable: "I do try to go out with my friends... But then sometimes when I come home and feel worse." "I usually talk to my mum more, because I feel like she's always with me, so understands what I go through every day," said the 18-year-old. "I'm so sorry, I feel really embarrassed to cry in front of you, but I think you're amazing" said Deborah, who has stage 4 bowel cancer.
