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

You couldn’t make it up, Jessie J says. At that moment preparing for her comeback record in nearly a decade, ecstatically in love with her recent boyfriend, and finally the parent to a young child after facing fertility challenges for ten years, feeling invincible. Suddenly in March she was found to have cancer in her breast.

The musician, real name J. Cornish, is famous for being brutally honest. The record, the provocatively titled album, was supposed to be an transparent story, tackling every ounce of devastation she’d endured since she last worked on songs (endometriosis, miscarriage, unsuccessful partnerships, psychological manipulation, suicidal thoughts) with characteristic openness. The lead track, No Secrets, was launched in April. But by then there remained a major undisclosed truth. The illness. Later next release, the upbeat Living My Best Life, debuted in May and she was talking to press about how she was thriving, while at the same time dealing with the disease. A month later she shared the news, and in July she received surgical treatment.

She gives me her best “What the fuck?” glance. “I release with a song called the track No Secrets. I’m doing every press talk, and they’re, like, ‘Any updates?’ and I’m, like, ‘Well, not much…’” Cornish has just had to call off performances because she’s yet to undergo follow-up surgery.

We’re at a photography studio in London. She is wearing a tan faux-leather coat, jeans with elaborate white patches, cream boots and big frames. Imagine biker chic meets vintage look. “I feel like I’m in the seventies and I should have a boyfriend with a big tache.” Easy Rider, I say, recalling the movie. “They used to call me that!” She smiles. She is sharp-witted, bold and direct. She says she has always been interested in humor and is hoping to make her first comedy performance in the coming year. “I love making people laugh. When performing I frequently joke about the crowd.”

Medical Challenges and Discovery

Cornish was preparing for an appearance at the awards show when she noticed an abnormality. “I quickly sought to get it looked at, had an scan, and they said, ‘It looks like nothing; your breasts are normal.’ And I insisted, ‘But I can feel it. I’ve got an achy arm and tingling in my hands whenever I rise.’ And they said, ‘We should biopsy it?’ It happened on March 28, the post-birthday.” It was a weekend eve. The specialist told her if it was serious she’d contact on the Monday. By then she had convinced herself it was fine. The way she tells it, it was just bad timing to receive a diagnosis when she had so much on.

“We’re two weeks away from releasing the album after a long hiatus and an extended break. And she contacted me and said, ‘Can you talk at six?’ And I was, like, ‘It’s virtual, probably routine.’ So I jump on the Zoom expecting it’s all going to be positive, and she goes, ‘Please take a seat.’ You know that sad tone they use? And she continues, ‘I’m so, so sorry but your reports have come back as high-grade cancer cells.’” What did you say? “I said, ‘Well, that’s not great. What awful 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 considered the operation frightening and surreal. “I fear going under. They walk you down. You know when you have emergency surgery you are wheeled, but this time I just walked with a gown on and my rear exposed. You feel like you’re in an episode of Black Mirror.” But, she notes, she’s been lucky. No chemo, no radiotherapy, just the procedure. “It’s terrible, but yet I’m grateful it was caught soon. The surgery happened a few months back and my affected breast now appears as a fruit under fabric.” She smiles again. “At least the nipple remains.”

The subsequent surgery is for health and appearance. Her chest, she observes, are now “asymmetrical. The implant is larger than before. So inconsiderate! I felt, why make it worse, I’m already having a hard period. How offensive! Ironically I said I’d not undergo augmentation because I’ve got perfectionism, and I know they’d never be ideal. Cancer ruined that plan.”

Past Medical Issues

The singer is no stranger to illness. She believes her perspective on the cancer has been so positive because she’s used to physical challenges. Frequently they align with career highs, acting as a reminder, or punch in the stomach, to make her recall not to take anything for granted. “Frankly, I feel the universe whispers, ‘You having a good time? Sit down.’ Ever since I was a child, it has consistently accompanied achievements 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 a musical (she was cast at the age of nine). That’s when she was found to have the cardiac issue Wolff-Parkinson-White syndrome, which can cause a fast heartbeat as well as vertigo and heart flutters. “I attended rehearsals intermittently on an intravenous line, and returning to the hospital at night.” She fast-forwards six years, and young Jessica has joined the girl group the group while enrolled in the Brit School. “I secured a deal, and I had a cerebral event. Then when I was planning to release songs in recently I had a automobile accident and my larynx moved up and I lost my voice for a long period.”

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