Jessie J just dropped a major health update — in a candid and surprisingly lighthearted Instagram video, she announced she has been diagnosed with breast cancer.

The “Bang Bang” singer shared the heavy news Tuesday — and is keeping an eye on that silver lining as she highlighted her cancer was found on the earlier side, noting … “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.”

The mother of one says she was diagnosed two months ago … ironically, just before she released her single, “No Secrets.”

Keeping her announcement as upbeat as possible, she pointed out the humor of it all, saying … “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.”

And despite going “back and forth” about whether or not she even wanted to reveal such a health update, Jessie said she’s sharing in hopes of helping someone else — the same way others’ stories have helped her.

JJ also said fans can expect her to “disappear for a bit” following her June 15 performance at London’s Summertime Ball, joking she’s going under the knife soon.

She quips … “It’s a very dramatic way to get a boob job.” Not clear if she’s actually getting a breast augmentation or if she’s just being sassy. Stay tuned.

The “Domino” hitmaker didn’t reveal whether or not her upcoming European and UK “No Secrets Tour 2025” will be affected — her first show is slated for August.

Jessie is known for being frank with her fans, previously opening up about her 2021 miscarriage, complications with Meniere’s disease and contracting COVID-19 during one of her shows.
