During the run of "Sunset Boulevard" at the West End's Adelphi Theatre in 1995, Paige discovered a lump in her breast, prompting her to consult her doctor, who at first reassured her there was nothing to be concerned about. She returned twice, and her doctor subsequently sent her for tests that confirmed the lump was cancerous, nine months after she discovered it. Continuing her role in the production Paige did not miss a show. Paige went in for day surgery on a Sunday due to her theatre commitments, had five years of medical treatment and completed a radiation programme. She has since described the period as "the most awful thing that's happened to me in my life".
