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

You wouldn’t believe it, Jessie J says. At that moment readying for her first album release in eight years, ecstatically in love with her current love, and finally the mom to a little one after facing fertility challenges for ten years, feeling invincible. Suddenly in spring she was found to have cancer in her breast.

The singer-songwriter, birth name Jess Cornish, is famous for being brutally honest. The album, her latest release, was meant as an transparent story, addressing every bit of hardship she’d experienced since she last worked on songs (endometrial issues, losing a baby, broken romances, emotional abuse, suicidal thoughts) with characteristic openness. The lead track, her single No Secrets, was launched in April. But by then there existed a huge secret. The illness. Later follow-up track, the upbeat Living My Best Life, was released in May and Cornish was giving interviews about how she was enjoying life to the fullest, while all the while dealing with the disease. Subsequently she went public, and in July she underwent breast removal surgery.

She offers me her best “What the fuck?” look. “I put out with a song called No Secrets. I’m conducting every press talk, and they inquire, ‘So what’s new with you?’ and I’m, like, ‘Erm, yeah, nothing …’” Cornish has just had to call off performances because she’s yet to undergo reconstructive surgery.

We’re at a photography studio in the capital. She is wearing a light brown synthetic jacket, blue jeans with elaborate white patches, beige footwear and large glasses. Think rocker vibe meets vintage look. “As if I’m in the 1970s and I should have a man with facial hair.” A biker reference, I say, recalling the film. “I was nicknamed that in school!” She grins. She is quick, bold and blunt. She says she has always been interested in humor and is hoping to make her standup debut in the coming year. “I love making people laugh. On stage I frequently joke about the fans.”

Health Struggles and Diagnosis

Cornish was getting ready for an appearance at the awards show when she noticed an abnormality. “I promptly visited to get it looked at, had an scan, and they were, like, ‘It appears fine; you’ve got really good dense breast tissue.’ And I insisted, ‘Yet I sense it. I’ve got an achy arm and numbness in my fingers whenever I rise.’ And they said, ‘Well, let’s just do a biopsy?’ It happened on March 28, the day after my birthday.” It was a Friday. The specialist told her if it was bad news she’d call on the start of the week. By then the singer had assured herself it was fine. The way she explains it, it was inopportune to receive a diagnosis when she had a busy schedule.

“It was a fortnight prior from launching this thing after a long hiatus and an extended break. And the doctor messaged and said, ‘Are you free at six?’ And I thought, ‘Oh, it’s a Zoom, it won’t be anything.’ So I log in thinking it’s all going to be fine, and she says, ‘Are you sitting down?.’ You know that sad tone they use? And she says, ‘I regret to inform you but your reports have come back as high-grade cancer cells.’” How did you respond? “I replied, ‘That’s unfortunate. That’s not fucking great timing.’ The first thing I thought was, ‘My child depends on me.’”

I’ve been labeled difficult for knowing myself

She considered the operation scary and bizarre. “I fear going under. They walk you down. During crises you go on a gurney, but now I just walked with a hospital gown and my backside out. You feel like you’re in an episode of Black Mirror.” But, Cornish says, she’s been fortunate. No chemotherapy or radiation, just the op. “Cancer is awful, but you know what? Thank fuck I found it early. The surgery happened recently and my one side now resembles a grapefruit under a tight bedsheet.” She smiles again. “At least the nipple remains.”

The subsequent surgery is both medical and cosmetic. Her breasts, she notes, are now “asymmetrical. They didn’t do an implant as small as my original. So inconsiderate! I thought, why make it worse, I’m already having a hard period. Such disrespect! Ironically I said I’d not undergo augmentation because I’ve got obsessive tendencies, and I know they’d never be perfect. Cancer ruined that plan.”

A History of Health Challenges

The singer is familiar with health problems. She thinks her attitude toward illness has been so upbeat because she’s experienced in health crises. Frequently they align with professional successes, functioning as a wake-up call, or blow, to remind her not to be complacent. “Honestly, I feel life goes, ‘Enjoying yourself? Sit down.’ Since childhood, it has often paired with high points for me; something severe or obscure has affected my well-being.”

She takes me back to her childhood, already making her debut featuring in the West End in the production (she was chosen at the age of nine years old). That’s when she was told about the heart condition Wolff-Parkinson-White syndrome, which can cause a fast heartbeat as well as dizziness and irregular beats. “I was going in and out of rehearsals on an intravenous line, and going back into hospital at night.” She fast-forwards six years, and 17-year-old Jess has joined the girl group Soul Deep while studying at the performing arts school. “I just got my first record deal, and I had a stroke. Then when I was planning to release songs in the year 2020 I had a automobile accident and my voice box shifted and I was unable to vocalize for a long period.”

Wow, I say, wait, I am overwhelmed. A stroke so young? She nods|agrees
