‘It has pushed me to live more fully’: Jessica Cornish on cancer, career returns and conquering the Chinese market

You can’t imagine it, Jessie J says. There she was gearing up for her new album launch in nearly a decade, blissfully happy with her current love, and finally the parent to a young child after dealing with conception issues for a decade, on top of the world. Suddenly in spring she was diagnosed with breast cancer.

The artist, real name J. Cornish, is renowned for telling it as it is. The LP, her latest release, was intended as an open book, addressing every bit of hardship she’d experienced since she last made an album (endometrial issues, losing a baby, broken romances, gaslighting, suicide) with her usual frankness. The initial release, the song No Secrets, was launched in April. But by then there remained a major undisclosed truth. The cancer. Then next release, the upbeat Living My Best Life, was released in May and she was talking to press about how she was living her best life, while still secretly coping with the disease. A month later she shared the news, and in early July she received surgical treatment.

She shoots me her best “Seriously?” expression. “I put out with a song called the track No Secrets. I’m conducting every press talk, and they inquire, ‘So what’s new with you?’ and I respond, ‘Erm, yeah, nothing …’” she has just had to postpone shows because she’s still waiting for cosmetic procedures.

We meet at a photo studio in the capital. She is sporting a beige fake-leather jacket, jeans with ornate white designs, cream boots and oversized specs. Imagine motorcycle style meets vintage look. “As if I’m in the seventies and I should have a partner with a mustache.” Like the film, I say, referencing the picture. “They used to call me that!” She grins. She is sharp-witted, irreverent and blunt. She says she has always been interested in humor and is aiming for her initial standup show next year. “I enjoy humor. When performing I frequently joke about the audience.”

Health Struggles and Diagnosis

Cornish was getting ready for an performance at the Baftas when she found a lump. “I promptly visited to get it checked, had an test, and they said, ‘It appears fine; your breasts are normal.’ And I insisted, ‘But I can feel it. My arm hurts and pins and needles in my hands whenever I get up.’ And they replied, ‘We should biopsy it?’ It happened on March 28, the following my birthday.” It was a Friday. The doctor told her if it was bad news she’d call on the Monday. By then the singer had convinced herself it was nothing. The way she explains it, it was simply too inconvenient to receive a diagnosis when she had a busy schedule.

“We’re two weeks away from releasing the album after a long hiatus and an extended break. And the doctor messaged and said, ‘Are you free at six?’ And I thought, ‘A video call, likely minor.’ So I log in believing it’s all going to be positive, and she says, ‘Are you sitting down?.’ You know that sad tone they use? And she reveals, ‘I’m so, so sorry but your reports have shown 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, ‘My child depends on me.’”

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

She found the surgery scary and bizarre. “I fear going under. You’re escorted. During crises you roll down in a bed, but then I just strolled down with a gown on and my backside out. You feel like you’re in an episode of Black Mirror.” But, she notes, she’s been blessed. No chemo, no radiotherapy, just the procedure. “Cancer is awful, but however Luckily it was detected early. I had the mastectomy four months ago and my right breast now resembles a odd shape.” A further beam. “At least the nipple remains.”

The follow-up procedure is therapeutic and aesthetic. Her breasts, she remarks, are now “uneven. The implant is larger than before. How rude! I thought, don’t add insult to injury, I’m already having a rough time. How offensive! Amusingly I said I’d not undergo augmentation because I’ve got obsessive tendencies, and I know they’d never be ideal. My plans were disrupted.”

Previous Struggles

Cornish is no stranger to illness. She thinks her perspective on the cancer has been so upbeat because she’s used to health crises. Many times they occur alongside peak moments, acting as a reminder, or punch in the stomach, to highlight not to be complacent. “Truly, I feel life goes, ‘Things going well? Take a seat.’ Since childhood, it has often paired with high points for me; something severe or obscure has happened to my health.”

She recalls to her youth, already starting her career featuring in the stage in the production (she was selected at the age of nine). That’s when she was found to have the cardiac issue Wolff-Parkinson-White syndrome, which can cause a rapid pulse as well as dizziness and palpitations. “I rehearsed between visits on an drip, and going back into hospital at night.” She jumps ahead several years, and teenage Jess has joined the female band Soul Deep while attending the Brit School. “I just got my first record deal, and I had a cerebral event. Then when I was planning to release songs in recently I had a collision and my larynx moved up and I lost my voice for a long period.”

Hey, I say, wait, I need a moment. A stroke so young? She nods|agrees
