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

You can’t imagine it, Jessie J says. At that moment preparing for her first album release in eight years, deeply enamored with her recent boyfriend, and at long last the mother of a toddler after dealing with conception issues for a decade, on top of the world. Then in March she was diagnosed with cancer in her breast.

The musician, birth name J. Cornish, is known for telling it as it is. The LP, Don’t Tease Me With a Good Time, was meant as an transparent story, dealing with every bit of hardship she’d endured since she last recorded music (endometrial issues, pregnancy loss, unsuccessful partnerships, psychological manipulation, suicidal thoughts) with typical candour. The initial release, the song No Secrets, was dropped in April. But by then there was a mighty secret. Her diagnosis. Later second single, her song Living My Best Life, came out in May and Cornish was speaking publicly about how she was thriving, while still secretly living with her cancer. A month later she went public, and in the start of summer she had a mastectomy.

She shoots me her best “Seriously?” glance. “I come out with a song called No Secrets. I’m giving every media appearance, and they ask, ‘So what’s new with you?’ and I answer, ‘Erm, yeah, nothing …’” she has just had to cancel tour dates because she’s awaiting reconstructive surgery.

We meet at a photography studio in the capital. She is wearing a tan faux-leather coat, jeans with ornate white designs, beige footwear and big frames. Think rocker vibe meets 1970s Nana Mouskouri. “It seems like I’m in the 1970s and I should have a boyfriend with a big tache.” Like the film, I say, recalling the picture. “They used to call me that!” She beams. Cornish is quick, unfiltered and filter-free. She says she has always been interested in humor and is aiming for her first comedy performance next year. “I like entertaining. When performing I basically roast the audience.”

Health Struggles and Diagnosis

She was getting ready for an appearance at the ceremony when she discovered a mass. “I immediately went to get it checked, had an scan, and they said, ‘It appears fine; you’ve got really good dense breast tissue.’ And I insisted, ‘However, it’s there. My arm hurts and pins and needles in my hands whenever I get up.’ And they suggested, ‘How about a biopsy?’ It happened on March 28, the post-birthday.” It was a Friday. The physician told her if it was concerning she’d contact on the start of the week. By then she 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 launching this thing after years away and an extended break. And the doctor messaged and said, ‘Can you talk at six?’ And I thought, ‘Oh, it’s a Zoom, it won’t be anything.’ So I log in expecting it’s all going to be good, and she goes, ‘You might want to sit.’ You know that sad tone they use? And she reveals, ‘I regret to inform you but your reports have indicated aggressive cancer.’” How did you respond? “I replied, ‘That’s unfortunate. That’s not fucking great timing.’ The first thing I thought was, ‘I can’t die because my son needs me.’”

I’ve been labeled difficult for knowing myself

She found the surgery scary and bizarre. “I hate being put under. You’re escorted. In urgent cases you roll down in a bed, but then I just walked with a gown on and my bum hanging out. You feel like you’re in an episode of Black Mirror.” But, Cornish says, she’s been blessed. Without chemo or radio, just the op. “Cancer sucks, man, but yet Luckily it was detected early. I had the mastectomy a few months back and my right breast now resembles a odd shape.” Another grin. “The nipple was preserved.”

The follow-up procedure is for health and appearance. Her boobs, she observes, are now “asymmetrical. They didn’t do an implant as small as my original. That’s impolite! I felt, no need to bully me, I’m already having a difficult experience. How offensive! It’s funny because I said I’d not undergo augmentation because I’ve got OCD, and I know they’d never be perfect. My plans were disrupted.”

A History of Health Challenges

Cornish is no stranger to illness. She believes her attitude toward illness has been so optimistic because she’s familiar with medical emergencies. Frequently they align with career highs, acting as a reminder, or blow, to make her recall not to take anything for granted. “Honestly, I feel the universe whispers, ‘You having a good time? Hold on.’ From a young age, it has always gone alongside achievements for me; something severe or obscure has affected my well-being.”

She reminisces to her childhood, already beginning featuring in the West End in the production (she was chosen at the age of nine). That’s when she was diagnosed with the cardiac issue a syndrome, which can cause a fast heartbeat 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 several years, and young Jessica has become part of the trio Soul Deep while studying at the academy. “I secured a deal, and I had a cerebral event. Then when I was ready to debut in 2020 I had a car crash and my voice box shifted and I was unable to vocalize for a twelve months.”

Hey, I say, wait, I am overwhelmed. You really had a stroke at 17? She nods|agrees
