‘It has taught me to embrace life more’: Jessie J on cancer, career returns and conquering the Chinese market

You wouldn’t believe it, the singer says. There she was gearing up for her comeback record in nearly a decade, blissfully happy with her newish partner, and at long last the mom to a little one after dealing with conception issues for a decade, feeling invincible. Then in March she was found to have a breast cancer diagnosis.

The musician, birth name J. Cornish, is famous for speaking her mind. The LP, her latest release, was intended as an open book, addressing every moment of pain she’d endured since she last made an album (endometrial issues, miscarriage, failed relationships, gaslighting, mental health struggles) with her usual frankness. The first single, her single No Secrets, was dropped in April. But by then there existed a huge secret. The cancer. Then follow-up track, Living My Best Life, debuted in May and Cornish was giving interviews about how she was living her best life, while still secretly dealing with her cancer. A month later she went public, and in July she underwent breast removal surgery.

She offers me her best “Seriously?” glance. “I come out with a song called the track No Secrets. I’m conducting every media appearance, and they ask, ‘So what’s new with you?’ and I’m, like, ‘Uh, nothing really’” Cornish has just had to cancel tour dates because she’s yet to undergo reconstructive surgery.

We’re at a photo studio in London. She is wearing a beige fake-leather jacket, blue jeans with ornate white designs, beige footwear and oversized specs. Picture biker chic meets 70s singer aesthetic. “I feel like I’m in the 70s and I should have a man with facial hair.” Like the film, I say, thinking of the movie. “That’s what people called me at school!” She beams. Jessie is fast-thinking, irreverent and filter-free. She says she has always been interested in humor and is planning to attempt her initial standup show next year. “I like entertaining. When performing I basically roast the audience.”

Personal Battles and News

The artist was preparing for an appearance at the awards show when she noticed an abnormality. “I quickly sought to get it examined, had an scan, and they said, ‘It appears fine; your breasts are normal.’ And I was, like, ‘Yet I sense it. I have arm pain and pins and needles in my hands whenever I wake up.’ And they replied, ‘Well, let’s just do a biopsy?’ It happened on March 28, the following my birthday.” It was a Friday. The specialist told her if it was bad news she’d contact on the start of the week. By then Cornish had convinced herself it was fine. The way she tells it, it was inopportune to receive a diagnosis when she had many commitments.

“We’re two weeks away from releasing the album after a long hiatus and no new music. And she contacted me and said, ‘Are you free at six?’ And I was, like, ‘A video call, likely minor.’ So I join the call believing it’s all going to be fine, and she goes, ‘Are you sitting down?.’ That sympathetic voice? And she says, ‘Unfortunately but your test results have indicated high-grade cancer cells.’” How did you respond? “I said, ‘Oh, that’s not ideal, is it?. The timing is terrible.’ Immediately I felt 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 scary and bizarre. “I hate being put under. They lead you. In urgent cases you roll down in a bed, but now I just walked with a gown on and my backside out. You feel like you’re in an episode of Black Mirror.” But, Cornish says, she’s been lucky. No chemotherapy or radiation, just the surgery. “Cancer is awful, but however Thank fuck I found it early. I underwent removal recently and my one side now appears as a odd shape.” A further beam. “I got to keep the nipple, though.”

The follow-up procedure is for health and appearance. Her chest, she remarks, are now “uneven. The size doesn’t match. That’s impolite! I reflected, no need to bully me, I’m already having a hard period. How offensive! Ironically I said I’d never get my boobs done because I’ve got obsessive tendencies, and I know they’d never be perfect. Illness changed that.”

A History of Health Challenges

She is no stranger to illness. She thinks her outlook on her diagnosis has been so upbeat because she’s experienced in physical challenges. They have often coincided with peak moments, functioning as a wake-up call, or shock, to make her recall not to be complacent. “Truly, I feel fate says, ‘Things going well? Sit down.’ Ever since I was a child, it has often paired with achievements for me; a serious or unusual issue has affected my well-being.”

She recalls to her childhood, already making her debut starring in the stage in the production (she was chosen at the age of 9). That’s when she was told about the medical problem a syndrome, which can cause a tachycardia as well as lightheadedness and palpitations. “I attended rehearsals intermittently on an intravenous line, and returning to the hospital at night.” She fast-forwards several years, and young Jessica has entered the female band the group while studying at the Brit School. “I signed my initial contract, and I had a cerebral event. Then when I was about to put out music in the year 2020 I had a car crash and my voice box shifted and I couldn’t sing for a year.”

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