Thurston shared a heartbreaking update on her cancer journey after spots were found on her liver, which could put her at a stage 4 diagnosis.

The wedding comes just weeks after Thurston, who starred in season 17 of "The Bachelorette," revealed in an emotional Instagram post that she had been diagnosed with breast cancer, only months after getting engaged to Arcuri. Last week, Thurston opened up about the diagnosis in an interview with " Good Morning America ."

"Bachelorette" alum Katie Thurston and Jeff Arcuri married Saturday ahead of the television personality's cancer treatment.
