Jessie J first revealed in June last year that she had been diagnosed with breast cancer.

The artist, known for hits including Price Tag and Bang Bang, underwent surgery during the summer and later postponed several performances while continuing treatment. At the time, she explained that she chose to speak publicly about her diagnosis partly to help herself process the experience, while also supporting others facing similar health struggles. “You’ve loved me through the good and hard times,” she previously told fans. “I didn’t want this to be any different.”
