Jessie J has been diagnosed with breast cancer, sharing that she’ll undergo surgery after her June 15 performance at the Summertime Ball in London.

Jessie J is providing an update on her health.

The “Bang Bang” singer shared that she was diagnosed with breast cancer over two months ago and has been “in and out of tests” this year. 

“I was diagnosed with early breast cancer,” Jessie said in an Instagram video June 3. “Cancer sucks in any form, but I’m holding on to the word ‘early.'”

The 37-year-old said she will undergo surgery after performing at the Summertime Ball 2025 concert in London on June 15. 

“It’s a very dramatic way to get a boob job,” she explained. “I am going to disappear for a bit after Summertime Ball to have my surgery, and I will come back with massive tits and more music.”

While Jessie—who shares son Sky, 2, with basketball player Chanan Safir Colman—noted that she hesitated to announce her diagnosis publicly, she decided to be “open” for multiple reasons.

“One, because, selfishly, I do not talk about it enough,” she continued. “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.”

And secondly, she wants to show her solidarity with others battling cancer, noting, “It breaks my heart that so many people are going through so much similar and worse—that’s the bit that kills me.”

Furthermore, Jessie felt the need to be candid on her life after releasing songs titled “No Secrets” in April and “Living My Best Life” last month.

She noted that the tracks were “all pre-planned before I found out about this. I mean, you can’t make it up.”

The Grammy nominee, who shared her diagnoses with ADHD and OCD last year, added, “It’s a weird topic and a weird situation.”

Still, her cancer journey has already taught her some important lessons.

“The timing of it has been mad but also beautiful and given me this incredible perspective in this time,” Jessie explained on her Instagram Story. “But honestly I need to process it and talk about it and, I need a hug. You have loved me through all my good and hard times. And I don’t want this to be any different.”
