‘It has pushed me to live more fully’: Jessie J on cancer, comebacks and cracking China

You couldn’t make it up, the singer states. At that moment gearing up for her comeback record in nearly a decade, blissfully happy with her newish partner, and at long last the parent to a young child after struggling to conceive for ten years, on top of the world. Then in March she was diagnosed with breast cancer.

The artist, actual name J. Cornish, is known for telling it as it is. The record, her latest release, was supposed to be an open book, tackling every ounce of devastation she’d faced since she last recorded music (endometrial issues, miscarriage, broken romances, psychological manipulation, suicidal thoughts) with characteristic openness. The lead track, her single No Secrets, was dropped in the spring. But by then there remained a major undisclosed truth. The illness. Then next release, her song Living My Best Life, came out in late spring and Cornish was speaking publicly about how she was thriving, while still secretly dealing with her cancer. Four weeks after she shared the news, and in early July she had a mastectomy.

She shoots me her best “What the fuck?” look. “I come out with a song called No Secrets. I’m conducting every interview, and they ask, ‘Any updates?’ and I respond, ‘Erm, yeah, nothing …’” she has just had to call off performances because she’s still waiting for cosmetic procedures.

Our interview takes place at a photo studio in the capital. She is dressed in a tan faux-leather coat, blue jeans with detailed white appliqués, off-white boots and big frames. Picture rocker vibe meets vintage look. “It seems like I’m in the 1970s and I should have a partner with a mustache.” A biker reference, I say, recalling the picture. “That’s what people called me at school!” She grins. Cornish is fast-thinking, bold and filter-free. She says she has always fancied doing comedy and is aiming for her standup debut next year. “I love making people laugh. On stage I often tease the fans.”

Personal Battles and News

The artist was planning an slot at the ceremony when she discovered a mass. “I immediately went to get it looked at, had an scan, and they said, ‘It looks like nothing; your tissue is healthy.’ And I responded, ‘But I can feel it. I’ve got an achy arm and pins and needles in my hands whenever I get up.’ And they said, ‘We should biopsy it?’ It happened on March 28, the post-birthday.” It was a weekend eve. The doctor told her if it was bad news she’d contact on the start of the week. By then she had convinced herself it was fine. The way she explains it, it was simply too inconvenient to receive a diagnosis when she had a busy schedule.

“It was a fortnight prior from releasing the album after eight years without an album and four years without a single. And the doctor messaged and said, ‘Can you talk at six?’ And I was, like, ‘It’s virtual, probably routine.’ So I jump on the Zoom believing it’s all going to be positive, and she informs me, ‘Are you sitting down?.’ You know that sad tone they use? And she says, ‘Unfortunately but your reports have come back as malignant cells.’” What was your reaction? “I answered, ‘That’s unfortunate. The timing is terrible.’ The first thing I thought was, ‘I have to survive for my boy.’”

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

She considered the operation frightening and surreal. “I fear going under. You’re escorted. You know when you have emergency surgery you roll down in a bed, but this time I just strolled down with a gown on and my bum hanging out. You feel like you’re in an episode of Black Mirror.” But, she notes, she’s been fortunate. No chemo, no radiotherapy, just the op. “Cancer is awful, but you know what? Thank fuck I found it early. The surgery happened recently and my affected breast now resembles a fruit under fabric.” Another grin. “The nipple was preserved.”

The follow-up procedure is both medical and cosmetic. Her chest, she remarks, are now “different sizes. The size doesn’t match. So inconsiderate! I thought, why make it worse, I’m already having a hard period. Such disrespect! Amusingly I said I’d not undergo augmentation because I’ve got OCD, and I know they’d never be flawless. My plans were disrupted.”

Previous Struggles

Cornish is no stranger to illness. She thinks her attitude toward illness has been so upbeat because she’s familiar with physical challenges. Frequently they align with professional successes, acting as a reminder, or punch in the stomach, to remind her not to assume everything is fine. “Frankly, I feel fate says, ‘Things going well? Sit down.’ Ever since I was a child, it has always gone alongside high points for me; something severe or obscure has impacted my body.”

She takes me back to her 11-year-old self, already beginning featuring in the stage in the production (she was chosen at the age of 9). That’s when she was told about the medical problem Wolff-Parkinson-White syndrome, which can cause a tachycardia as well as lightheadedness and heart flutters. “I rehearsed between visits on an IV drip, and going back into hospital at night.” She skips forward six years, and teenage Jess has joined the girl group Soul Deep while attending the performing arts school. “I secured a deal, and I had a brain incident. Then when I was ready to debut in the year 2020 I had a collision and my throat was injured and I couldn’t sing for a year.”

Oi, I say, wait, I can’t keep up. At just 17? She nods|agrees
