Just days after her defeat in the 2025 federal election, former MP and medical expert Dr. Katie Allen shared a deeply personal health update. She announced she has been diagnosed with stage 4 cholangiocarcinoma, a rare and aggressive cancer of the bile ducts.

She posted the news on social media, saying she is prepared to face this difficult journey with courage, focus, and strength.

Former MP’s Return to Politics Ends in Defeat

Dr. Allen, who previously represented Higgins from 2019 to 2022, ran for the seat of Chisholm in this year’s federal election. Despite her efforts, she lost to Labor MP Carina Garland by a margin of more than 9,000 votes.
