Shauntelle came home on Thursday
Carlow's Shauntelle "Shan" Tynan will appear on this Friday's Late Late Show.
Shan was diagnosed with a rare form of cancer at just 16-years-old.
After eight months of chemo with little success, her mother Leona started the mammoth task of raising €600,000 so Shan could take part in US clinical trials that had the potential to save her life.
In Texas for the last year, she returned to Ireland this week having been declared cancer free.
She joins host Ryan Tubridy to share her story.
