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

You can’t imagine it, the singer states. There she was readying for her new album launch in eight years, ecstatically in love with her recent boyfriend, and finally the parent to a young child after facing fertility challenges for ten years, riding high. Suddenly in March she was diagnosed with cancer in her breast.

The musician, actual name J. Cornish, is renowned for telling it as it is. The record, Don’t Tease Me With a Good Time, was supposed to be an open book, tackling every bit of hardship she’d experienced since she last worked on songs (a gynecological condition, losing a baby, broken romances, gaslighting, suicide) with her usual frankness. The first single, the song No Secrets, was launched in April. But by then there remained a major undisclosed truth. The cancer. Then follow-up track, Living My Best Life, was released in late spring and Cornish was talking to press about how she was thriving, while still secretly living with breast cancer. Subsequently she went public, and in the start of summer she received surgical treatment.

She gives me her best “Seriously?” look. “I come out with a song called No Secrets. I’m conducting every interview, and they inquire, ‘What’s happening?’ and I answer, ‘Erm, yeah, nothing …’” she has just had to postpone shows because she’s yet to undergo follow-up surgery.

We meet at a photo studio in London. She is wearing a tan faux-leather coat, blue jeans with detailed white appliqués, beige footwear and oversized specs. Think biker chic meets 1970s Nana Mouskouri. “I feel like I’m in the 1970s and I should have a boyfriend with a big tache.” A biker reference, I say, referencing the film. “That’s what people called me at school!” She smiles. She is fast-thinking, irreverent and direct. She says she has always wanted to try comedy and is hoping to make her standup debut next year. “I like entertaining. On stage I frequently joke about the audience.”

Medical Challenges and Discovery

Cornish was preparing for an performance at the awards show when she noticed an abnormality. “I promptly visited to get it examined, had an ultrasound, and they were, like, ‘It appears fine; your tissue is healthy.’ And I was, like, ‘However, it’s there. My arm hurts and numbness in my fingers whenever I wake up.’ And they replied, ‘We should biopsy it?’ That was 28 March, the post-birthday.” It was a Friday. The specialist told her if it was serious she’d contact on the start of the week. By then the singer had assured herself it was fine. The way she describes it, it was inopportune to face illness when she had a busy schedule.

“We’re two weeks away from debuting the project after eight years without an album and an extended break. And she [the doctor] texted and said, ‘Are you free at six?’ And I assumed, ‘Oh, it’s a Zoom, it won’t be anything.’ So I log in expecting it’s all going to be positive, and she informs me, ‘You might want to sit.’ You know that sad tone they use? And she reveals, ‘I regret to inform you but your test results have shown aggressive cancer.’” What was your reaction? “I answered, ‘Oh, that’s not ideal, is it?. The timing is terrible.’ The first thing I thought was, ‘I have to survive for my boy.’”

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

She considered the operation terrifying and absurd. “I hate being put under. You’re escorted. In urgent cases you go on a gurney, but this time I just strolled down with a medical attire and my rear exposed. It felt surreal.” But, Cornish says, she’s been fortunate. Without chemo or radio, just the surgery. “Cancer sucks, man, but however Thank fuck I found it early. I had the mastectomy four months ago and my one side now appears as a grapefruit under a tight bedsheet.” A further beam. “I got to keep the nipple, though.”

The subsequent surgery is for health and appearance. Her chest, she notes, are now “different sizes. The implant is larger than before. So inconsiderate! I reflected, why make it worse, I’m already having a difficult experience. How offensive! Ironically I said I’d never get my boobs done because I’ve got obsessive tendencies, and I know they’d never be ideal. My plans were disrupted.”

Past Medical Issues

She is accustomed to medical issues. She believes her perspective on the cancer has been so upbeat because she’s used to health crises. Frequently they align with professional successes, functioning as a wake-up call, or blow, to highlight not to take anything for granted. “Truly, I feel the universe whispers, ‘Things going well? Take a seat.’ From a young age, it has often paired with achievements for me; a serious or unusual issue has happened to my health.”

She recalls to her 11-year-old self, already starting her career performing in the stage in a musical (she was chosen at the age of 9). That’s when she was diagnosed with the cardiac issue a syndrome, which can cause a rapid pulse as well as lightheadedness and irregular beats. “I rehearsed between visits on an intravenous line, and being readmitted at night.” She skips forward several years, and teenage Jess has entered the trio Soul Deep while studying at the academy. “I just got my first record deal, and I had a brain incident. Then when I was planning to release songs in the year 2020 I had a car crash and my throat was injured and I was unable to vocalize for a long period.”

Oi, I say, hold on, I can’t keep up. You really had a stroke at 17? She nods|agrees
