‘It has pushed me to live more fully’: Jessica Cornish on her health battle, comebacks and cracking China

You can’t imagine it, Jessie J remarks. At that moment gearing up for her comeback record in nearly a decade, blissfully happy with her current love, and at long last the mom to a little one after struggling to conceive for a decade, on top of the world. Then in March she was found to have breast cancer.

The musician, birth name J. Cornish, is known for being brutally honest. The record, Don’t Tease Me With a Good Time, was supposed to be an transparent story, addressing every moment of pain she’d faced since she last made an album (a gynecological condition, losing a baby, failed relationships, gaslighting, mental health struggles) with typical candour. The lead track, No Secrets, was dropped in the spring. But by then there remained a major undisclosed truth. Her diagnosis. Later follow-up track, the upbeat Living My Best Life, was released in late spring and the artist was giving interviews about how she was thriving, while all the while dealing with breast cancer. A month later she disclosed her condition, and in July she underwent breast removal surgery.

She gives me her best “What the fuck?” glance. “I put out with a song called No Secrets. I’m doing every media appearance, and they inquire, ‘Any updates?’ and I’m, like, ‘Uh, nothing really’” she has just had to cancel tour dates because she’s still waiting for reconstructive surgery.

We meet at a studio in London. She is dressed in a beige fake-leather jacket, jeans with elaborate white patches, off-white boots and oversized specs. Think biker chic meets vintage look. “As if I’m in the 70s and I should have a partner with a mustache.” A biker reference, I say, recalling the picture. “I was nicknamed that in school!” She smiles. Cornish is sharp-witted, bold and blunt. She says she has always fancied doing comedy and is aiming for her standup debut in the coming year. “I enjoy humor. When performing I often tease the crowd.”

Personal Battles and News

The artist was planning an appearance at the Baftas when she discovered a mass. “I quickly sought to get it checked, had an test, and they said, ‘It seems benign; your tissue is healthy.’ And I insisted, ‘But I can feel it. I have arm pain and tingling in my hands whenever I rise.’ And they replied, ‘We should biopsy it?’ That was 28 March, 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 she had assured herself it was fine. The way she describes it, it was simply too inconvenient to receive a diagnosis when she had many commitments.

“It was a fortnight prior from releasing the album after a long hiatus and an extended break. And she [the doctor] texted and said, ‘Is six okay?’ And I thought, ‘A video call, likely minor.’ So I jump on the Zoom expecting it’s all going to be good, and she goes, ‘Please take a seat.’ You know that sad tone they use? And she says, ‘I’m so, so sorry but your biopsy results have indicated high-grade cancer cells.’” How did you respond? “I answered, ‘That’s unfortunate. What awful timing.’ My initial thought was, ‘I can’t die because my son needs me.’”

I’ve been labeled difficult for knowing myself

She found the surgery terrifying and absurd. “I fear going under. They walk you down. In urgent cases you go on a gurney, but then I just marched with a hospital gown and my rear exposed. It felt surreal.” But, Cornish says, she’s been lucky. No chemotherapy or radiation, just the procedure. “Cancer sucks, man, but however I’m grateful it was caught soon. The surgery happened recently and my one side now looks like a fruit under fabric.” Another grin. “At least the nipple remains.”

The follow-up procedure is both medical and cosmetic. Her boobs, she remarks, are now “asymmetrical. The implant is larger than before. How rude! I felt, no need to bully me, I’m already having a difficult experience. So rude! Amusingly 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.”

Previous Struggles

She is accustomed to medical issues. She feels her perspective on the cancer has been so positive because she’s experienced in medical emergencies. They have often coincided with peak moments, acting as a reminder, or shock, to remind her not to be complacent. “Truly, I feel life goes, ‘You having a good time? Hold on.’ Ever since I was a child, it has always gone alongside achievements for me; something severe or obscure has impacted my body.”

She takes me back to her youth, already starting her career featuring in the West End in Whistle Down the Wind (she was cast at the age of 9). That’s when she was told about the medical problem WPW, which can cause a fast heartbeat as well as dizziness and palpitations. “I attended rehearsals intermittently on an drip, and going back into hospital at night.” She jumps ahead six years, and 17-year-old Jess has become part of the trio Soul Deep while attending the academy. “I just got my first record deal, and I had a stroke. Then when I was about to put out music in recently I had a automobile accident and my larynx moved up and I lost my voice for a long period.”

Wow, I say, slow down, I am overwhelmed. You really had a stroke at 17? She nods|agrees
