‘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 states. There she was gearing up for her new album launch in eight years, ecstatically in love with her newish partner, and at long last the mom to a little one after facing fertility challenges for a decade, riding high. Then in spring she was diagnosed with breast cancer.

The musician, actual name J. Cornish, is known for speaking her mind. The record, the provocatively titled album, was meant as an transparent story, addressing every ounce of devastation she’d experienced since she last recorded music (endometrial issues, losing a baby, unsuccessful partnerships, gaslighting, mental health struggles) with characteristic openness. The initial release, her single No Secrets, was dropped in the spring. But by then there remained a major undisclosed truth. The illness. Then next release, the upbeat Living My Best Life, was released in late spring and Cornish was giving interviews about how she was living her best life, while still secretly coping with the disease. Four weeks after she disclosed her condition, and in the start of summer she had a mastectomy.

She offers me her best “What the fuck?” look. “I come out with a song called the track No Secrets. I’m doing every media appearance, and they ask, ‘So what’s new with you?’ and I respond, ‘Uh, nothing really’” the singer has just had to call off performances because she’s awaiting follow-up surgery.

We meet at a photo studio in London. She is sporting a beige fake-leather jacket, jeans with ornate white designs, beige footwear and big frames. Think motorcycle style meets 70s singer aesthetic. “I feel like I’m in the 70s and I should have a boyfriend with a big tache.” A biker reference, I say, thinking of the film. “That’s what people called me at school!” She smiles. Cornish is sharp-witted, unfiltered and direct. She says she has always fancied doing comedy and is hoping to make her first comedy performance soon. “I like entertaining. During performances I often tease the crowd.”

Health Struggles and Diagnosis

Cornish was planning an performance at the ceremony when she found a lump. “I immediately went to get it examined, had an test, and they were, like, ‘It seems benign; your breasts are normal.’ And I was, like, ‘However, it’s there. My arm hurts and numbness in my fingers whenever I get up.’ And they replied, ‘How about a biopsy?’ It happened on March 28, the post-birthday.” It was a weekend eve. The doctor told her if it was serious she’d reach out on the Monday. By then Cornish had assured herself it was nothing. The way she explains it, it was inopportune to get cancer when she had a busy schedule.

“We’re two weeks away from debuting the project after a long hiatus and no new music. And she contacted me and said, ‘Is six okay?’ And I assumed, ‘Oh, it’s a Zoom, it won’t be anything.’ So I log in thinking it’s all going to be good, and she says, ‘Are you sitting down?.’ You know that sad tone they use? And she says, ‘I regret to inform you but your test results have indicated aggressive cancer.’” What did you say? “I answered, ‘That’s unfortunate. That’s not fucking great timing.’ The first thing I thought was, ‘I have to survive for my boy.’”

Some men find me challenging due to my self-awareness

She found the surgery terrifying and absurd. “I hate being put under. You’re escorted. In urgent cases you are wheeled, but then I just walked with a medical attire and my backside out. You feel like you’re in an episode of Black Mirror.” But, she adds, she’s been lucky. No chemo, no radiotherapy, just the op. “Cancer sucks, man, but you know what? I’m grateful it was caught soon. The surgery happened recently and my one side now appears as a fruit under fabric.” She smiles again. “The nipple was preserved.”

The follow-up procedure is for health and appearance. Her breasts, she remarks, are now “different sizes. They didn’t do an implant as small as my original. That’s impolite! I reflected, no need to bully me, I’m already having a hard period. How offensive! Amusingly I said I’d not undergo augmentation because I’ve got perfectionism, and I know they’d never be flawless. Cancer ruined that plan.”

Previous Struggles

She is accustomed to medical issues. She thinks her outlook on her diagnosis has been so optimistic because she’s familiar with medical emergencies. They have often coincided with professional successes, serving as a tap on the shoulder, or blow, to remind her not to be complacent. “Truly, I feel the universe whispers, ‘Enjoying yourself? Hold on.’ Ever since I was a child, it has always gone alongside high points for me; a serious or unusual issue has affected my well-being.”

She takes me back to her youth, already beginning featuring in the West End in Whistle Down the Wind (she was chosen at the age of nine years old). That’s when she was diagnosed with the heart condition a syndrome, which can cause a rapid pulse as well as dizziness and heart flutters. “I rehearsed between visits on an IV drip, and returning to the hospital at night.” She jumps ahead half a dozen years, and young Jessica has become part of the girl group Soul Deep while studying at the performing arts school. “I signed my initial contract, and I had a cerebral event. Then when I was planning to release songs in the year 2020 I had a collision and my larynx moved up and I couldn’t sing for a twelve months.”

Hey, I say, slow down, I am overwhelmed. At just 17? She nods|agrees
