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

You wouldn’t believe it, Jessie J remarks. At that moment preparing for her new album launch in nearly a decade, blissfully happy with her current love, and finally the mom to a little one after facing fertility challenges for a decade, feeling invincible. Then in March she was found to have a breast cancer diagnosis.

The singer-songwriter, real name J. Cornish, is famous for telling it as it is. The album, her latest release, was supposed to be an open book, dealing with every bit of hardship she’d endured since she last made an album (endometrial issues, losing a baby, unsuccessful partnerships, emotional abuse, suicide) with characteristic openness. The first single, the song No Secrets, was launched in April. But by then there existed a huge secret. The illness. Later second single, the upbeat Living My Best Life, came out in late spring and Cornish was giving interviews about how she was enjoying life to the fullest, while at the same time living with the disease. Four weeks after she went public, and in early July she underwent breast removal surgery.

She offers me her best “What the fuck?” look. “I release with a song called No Secrets. I’m conducting every interview, and they’re, like, ‘Any updates?’ and I respond, ‘Erm, yeah, nothing …’” she has just had to cancel tour dates because she’s still waiting for cosmetic procedures.

Our interview takes place at a studio in London. She is wearing a light brown synthetic jacket, denim trousers with elaborate white patches, off-white boots and oversized specs. Think biker chic meets 70s singer aesthetic. “I feel like I’m in the 1970s and I should have a partner with a mustache.” A biker reference, I say, thinking of the picture. “They used to call me that!” She grins. Jessie is quick, unfiltered and filter-free. She says she has always fancied doing comedy and is planning to attempt her initial standup show soon. “I love making people laugh. During performances I basically roast the crowd.”

Medical Challenges and Discovery

She was preparing for an performance at the ceremony when she noticed an abnormality. “I promptly visited to get it examined, had an test, and they said, ‘It looks like nothing; you’ve got really good dense breast tissue.’ And I was, like, ‘Yet I sense it. I’ve got an achy arm and numbness in my fingers whenever I wake up.’ And they suggested, ‘We should biopsy it?’ That was 28 March, the post-birthday.” It was a weekend eve. The doctor told her if it was bad news she’d call on the start of the week. By then she had persuaded herself it was nothing. The way she tells it, it was inopportune to face illness when she had many commitments.

“Just two weeks before from launching this thing after years away and no new music. And she [the doctor] texted and said, ‘Are you free at six?’ And I assumed, ‘Oh, it’s a Zoom, it won’t be anything.’ So I jump on the Zoom believing it’s all going to be positive, and she goes, ‘You might want to sit.’ The solemn tone? And she continues, ‘Unfortunately but your test results have indicated malignant cells.’” What did you say? “I said, ‘That’s unfortunate. The timing is terrible.’ My initial thought was, ‘I can’t die because my son needs me.’”

Men have called me difficult because I’m a strong person who understands who I am

She considered the operation frightening and surreal. “I hate being put under. You’re escorted. During crises you go on a gurney, but this time I just marched with a medical attire and my bum hanging out. You feel like you’re in an episode of Black Mirror.” But, she adds, she’s been fortunate. No chemotherapy or radiation, just the op. “Cancer sucks, man, but you know what? Luckily it was detected early. I had the mastectomy four months ago and my one side now resembles a fruit under fabric.” She smiles again. “The nipple was preserved.”

The next operation is both medical and cosmetic. Her chest, she remarks, are now “asymmetrical. The size doesn’t match. So inconsiderate! I reflected, don’t add insult to injury, I’m already having a rough time. Such disrespect! It’s funny because I said I’d avoid breast surgery because I’ve got obsessive tendencies, and I know they’d never be perfect. My plans were disrupted.”

Previous Struggles

The singer is familiar with health problems. She believes her attitude toward illness has been so upbeat because she’s experienced in medical emergencies. Many times they occur alongside professional successes, serving as a tap on the shoulder, or blow, to remind her not to assume everything is fine. “Honestly, I feel fate says, ‘Things going well? Take a seat.’ From a young age, it has consistently accompanied achievements for me; something severe or obscure has affected my well-being.”

She takes me back to her childhood, already starting her career featuring in the West End in Whistle Down the Wind (she was cast at the age of 9). That’s when she was told about the cardiac issue WPW, which can cause a rapid pulse as well as vertigo and palpitations. “I rehearsed between visits on an IV drip, and being readmitted at night.” She jumps ahead half a dozen years, and 17-year-old Jess has entered the female band Soul Deep while attending the academy. “I signed my initial contract, and I had a brain incident. Then when I was planning to release songs in 2020 I had a collision and my throat was injured and I couldn’t sing for a year.”

Wow, I say, wait, I need a moment. At just 17? She nods|agrees
