Pop Star Jessie J Tells Fans She's 'Going To Disappear For A Bit' After Revealing Cancer Diagnosis

British pop star Jessie J shared some unfortunate news with her loved ones and fans in a post on Instagram recently.

A Grammy-nominated singer with a catalog going back to 2011's hit Domino, she said she had been diagnosed with early stage breast cancer, and announced that she would be out of public life for awhile while undergoing treatment, including surgery.

She said sharing things had helped her weather storms in the past.

“I just wanted to be open and share it. One, because, selfishly, I do not talk about it enough. I’m not processing it because I’m working so hard."

"I also know how much sharing in the past has helped me with other people giving me their love and support and also their own stories. I’m an open book."

The timing of her diagnosis was notable. In 2025, she has been following a carefully planned release calendar, with her song "No Secrets" dropping just over a month ago.

Right around the same time was her diagnosis, with her planning appearances around tests and doctors' appointments. Her next song to be released, she noted, will be "Living My Best Life."

Regarding a cancer diagnosis between those two titles, she said, "I mean you can't make it up."

She joked in the caption of her post:

"Is it too soon to do a remix called ‘Living my breast life’?"

Messages of care and support came flooding in.

Jessie J even found some humor in the announcement, joking about how she was glad that she "will get to keep [her] nipples," and that it's "a very dramatic way to get a boob job."

"And I will come back with massive tits and more music."

People riffed on that joke when sending their support.
