Jessie J has been diagnosed with "early" breast cancer - and she will undergo surgery later this month

She said in an Instagram video: "Before 'No Secrets' came out, I was diagnosed with early breast cancer.

"I'm highlighting the word 'early'.

"Cancer sucks in any form but I'm holding onto the word early.

"I have been in and out of tests throughout this whole period."

Jessie went "back and forth" with herself about whether she should share her news, due to there being "lots of opinions outside".

But the 'Who You Are' singer felt she should tell all, particularly because of the name of her latest single, 'No Secrets', which was inspired by a miscarriage she had in 2021.

She said: "To get diagnosed with this, as I'm putting out a song called 'No Secrets' right before a song called 'Living My Best Life,' which was all pre-planned before I found out about this, I mean you can't make it up.

"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. It breaks my heart that so many people are going through so much, similar and worse. That's the bit that kills me."

Jessie is still planning to perform at this year's Capital Summertime Ball, which will take place on June 15th at London's Wembley Stadium, but afterwards she will undergo surgery and "disappear for a bit".

She said: "It wasn't something I'd planned, but yeah.

"I'm getting to keep my nipples, that's good. It's a weird topic and a weird situation.

"I am going to disappear for a bit after Summertime Ball to have my surgery, and I will come back with massive t*ts and more music."

The 'Price Tag' hitmaker joked: "It's a very dramatic way to get a boob job."

Jessie - who has son Sky, two, with basketball star Chanan Colman - also quipped she might release a remix of her upcoming single 'Living My Best Life', and call it 'Living My Breast Life'.

She wrote in an Instagram caption: "No (more) Secrets and is it too soon to do a remix called 'Living my breast life'?

"All jokes aside (You know it's one of the ways I get through hard times) This last 2 months have been so amazing, and having this go on along side it on the sideline's has given me the most incredible perspective. BUT... Your girl needs a hug.

"Also not getting massive t*ts. Or am I? No no...I must stop joking. (sic)"
