Thurston, who was the Bachelorette lead for season 17 of the hit reality dating show, was diagnosed with breast cancer in February. A PET scan the next month revealed additional spots on her liver were also cancerous. She is scheduled to begin treatment next month.

Former “Bachelorette” Katie Thurston confirmed Friday on Instagram that her breast cancer is Stage 4 and has spread to her liver. In a candid update to viewers, set 43 days after she received a cancer diagnosis, Thurston shared that she has not started treatment yet due to testing and her decision to “focus on fertility” beforehand.
