‘It has pushed me to live more fully’: Jessie J on her health battle, career returns and conquering the Chinese market

You can’t imagine it, the singer states. At that moment readying for her new album launch in nearly a decade, deeply enamored with her recent boyfriend, and at long last the parent to a young child after dealing with conception issues for ten years, on top of the world. Then in March she was diagnosed with cancer in her breast.

The artist, birth name J. Cornish, is famous for being brutally honest. The album, her latest release, was meant as an open book, tackling every ounce of devastation she’d faced since she last worked on songs (a gynecological condition, pregnancy loss, unsuccessful partnerships, emotional abuse, suicide) with her usual frankness. The initial release, the song No Secrets, was launched in the spring. But by then there remained a major undisclosed truth. Her diagnosis. Later next release, Living My Best Life, debuted in May and Cornish was giving interviews about how she was thriving, while still secretly dealing with her cancer. Four weeks after she went public, and in July she underwent breast removal surgery.

She offers me her best “Seriously?” glance. “I put out with a song called the track No Secrets. I’m conducting every press talk, and they’re, like, ‘Any updates?’ and I’m, like, ‘Erm, yeah, nothing …’” she has just had to call off performances because she’s awaiting reconstructive surgery.

We meet at a photo studio in London. She is wearing a beige fake-leather jacket, denim trousers with elaborate white patches, beige footwear and large glasses. Picture biker chic meets 1970s Nana Mouskouri. “I feel like I’m in the seventies and I should have a man with facial hair.” Easy Rider, I say, thinking of the film. “That’s what people called me at school!” She beams. Cornish is sharp-witted, irreverent and filter-free. She says she has always wanted to try comedy and is aiming for her first comedy performance next year. “I like entertaining. During performances I basically roast the crowd.”

Medical Challenges and Discovery

Cornish was getting ready for an performance at the awards show when she discovered a mass. “I immediately went to get it examined, had an ultrasound, and they said, ‘It appears fine; you’ve got really good dense breast tissue.’ And I responded, ‘But I can feel it. My arm hurts and numbness in my fingers whenever I rise.’ And they suggested, ‘Well, let’s just do a biopsy?’ It happened on March 28, the post-birthday.” It was a Friday. The doctor told her if it was serious she’d reach out on the start of the week. By then the singer had persuaded herself it was okay. The way she explains it, it was inopportune to get cancer when she had many commitments.

“Just two weeks before from debuting the project after a long hiatus and an extended break. And she contacted me and said, ‘Is six okay?’ And I thought, ‘It’s virtual, probably routine.’ So I log in thinking it’s all going to be fine, and she says, ‘Please take a seat.’ You know that sad tone they use? And she reveals, ‘Unfortunately but your biopsy results have shown malignant cells.’” What did you say? “I said, ‘Well, that’s not great. The timing is terrible.’ My initial thought was, ‘I can’t die because my son needs me.’”

I’ve been labeled difficult for knowing myself

She viewed the procedure terrifying and absurd. “I hate being put under. You’re escorted. In urgent cases you are wheeled, but then I just walked with a gown on and my rear exposed. You feel like you’re in an episode of Black Mirror.” But, Cornish says, she’s been blessed. Without chemo or radio, just the surgery. “Cancer is awful, but however Luckily it was detected early. The surgery happened four months ago and my one side now looks like a fruit under fabric.” Another grin. “At least the nipple remains.”

The next operation is both medical and cosmetic. Her boobs, she observes, are now “asymmetrical. They didn’t do an implant as small as my original. So inconsiderate! I felt, no need to bully me, I’m already having a difficult experience. So rude! Amusingly I said I’d never get my boobs done because I’ve got OCD, and I know they’d never be flawless. Cancer ruined that plan.”

A History of Health Challenges

She is accustomed to medical issues. She believes her perspective on the cancer has been so optimistic because she’s experienced in medical emergencies. Many times they occur alongside peak moments, functioning as a wake-up call, or punch in the stomach, to make her recall not to be complacent. “Honestly, I feel life goes, ‘Enjoying yourself? Hold on.’ From a young age, it has often paired with high points for me; a major or strange event has happened to my health.”

She reminisces to her youth, already making her debut featuring in the London theater in the production (she was selected at the age of nine). That’s when she was told about the cardiac issue WPW, which can cause a rapid pulse as well as vertigo and palpitations. “I attended rehearsals intermittently on an IV drip, and going back into hospital at night.” She fast-forwards several years, and teenage Jess has joined the female band Soul Deep while attending the academy. “I signed my initial contract, and I had a stroke. Then when I was planning to release songs in the year 2020 I had a collision and my voice box shifted and I couldn’t sing for a long period.”

Hey, I say, hold on, I need a moment. At just 17? She nods|agrees
