‘It has pushed me to live more fully’: Jessie J on her health battle, career returns and cracking China

You wouldn’t believe it, the singer states. There she was readying for her new album launch 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 ten years, riding high. Suddenly in March she was diagnosed with a breast cancer diagnosis.

The musician, actual name J. Cornish, is known for telling it as it is. The album, her latest release, was supposed to be an transparent story, tackling every moment of pain she’d endured since she last made an album (a gynecological condition, miscarriage, unsuccessful partnerships, gaslighting, mental health struggles) with typical candour. The initial release, the song No Secrets, was released in April. But by then there was a mighty secret. Her diagnosis. Then next release, Living My Best Life, was released in May and the artist was speaking publicly about how she was living her best life, while all the while living with her cancer. A month later she disclosed her condition, and in the start of summer she underwent breast removal surgery.

She shoots me her best “Are you kidding?” look. “I release with a song called No Secrets. I’m doing every press talk, and they’re, like, ‘Any updates?’ and I’m, like, ‘Erm, yeah, nothing …’” Cornish has just had to postpone shows because she’s yet to undergo cosmetic procedures.

We’re at a studio in London. She is wearing a light brown synthetic jacket, jeans with elaborate white patches, off-white boots and large glasses. Imagine rocker vibe meets vintage look. “As if I’m in the 1970s and I should have a boyfriend with a big tache.” Easy Rider, I say, recalling the picture. “That’s what people called me at school!” She beams. Cornish is quick, irreverent and filter-free. She says she has always been interested in humor and is planning to attempt her initial standup show next year. “I like entertaining. On stage I basically roast the audience.”

Health Struggles and Diagnosis

The artist was preparing for an appearance at the ceremony when she found a lump. “I quickly sought to get it checked, had an test, and they told me, ‘It appears fine; you’ve got really good dense breast tissue.’ And I was, like, ‘Yet I sense it. My arm hurts and tingling in my hands whenever I get up.’ And they suggested, ‘How about a biopsy?’ It happened on March 28, the day after my birthday.” It was a weekend eve. The doctor told her if it was serious she’d contact on the Monday. By then the singer had persuaded herself it was nothing. The way she explains it, it was inopportune to receive a diagnosis when she had many commitments.

“We’re two weeks away from debuting the project after years away and an extended break. And the doctor messaged and said, ‘Is six okay?’ And I assumed, ‘A video call, likely minor.’ So I jump on the Zoom thinking it’s all going to be fine, and she informs me, ‘Please take a seat.’ The solemn tone? And she reveals, ‘Unfortunately but your test results have come back as aggressive cancer.’” What was your reaction? “I said, ‘Well, that’s not great. What awful timing.’ Immediately I felt was, ‘I can’t die because my son needs me.’”

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

She considered the operation scary and bizarre. “I hate being put under. You’re escorted. During crises you go on a gurney, but then I just walked with a hospital gown 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 yet Luckily it was detected early. The surgery happened four months ago and my affected breast now resembles a grapefruit under a tight bedsheet.” Another grin. “At least the nipple remains.”

The subsequent surgery is therapeutic and aesthetic. Her chest, she observes, are now “uneven. The size doesn’t match. How rude! I felt, no need to bully me, I’m already having a rough time. So rude! Amusingly I said I’d not undergo augmentation because I’ve got OCD, and I know they’d never be ideal. Illness changed that.”

Past Medical Issues

She is no stranger to illness. She believes her perspective on the cancer has been so optimistic because she’s familiar with health crises. Many times they occur alongside peak moments, functioning as a wake-up call, or shock, to remind her not to be complacent. “Honestly, I feel life goes, ‘Enjoying yourself? Take a seat.’ From a young age, it has always gone alongside high points for me; a major or strange event has impacted my body.”

She takes me back to her 11-year-old self, already starting her career starring in the stage in a musical (she was chosen at the age of nine years old). That’s when she was found to have the cardiac issue WPW, which can cause a rapid pulse as well as vertigo and heart flutters. “I was going in and out of rehearsals on an IV drip, and going back into hospital at night.” She skips forward half a dozen years, and teenage 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 brain incident. Then when I was planning to release songs in 2020 I had a collision and my voice box shifted and I was unable to vocalize for a long period.”

Wow, I say, slow down, I need a moment. A stroke so young? She nods|agrees
