‘It has made me live life more’: Jessie J on her health battle, comebacks and cracking China

You wouldn’t believe it, the singer states. At that moment gearing up for her comeback record in nearly a decade, ecstatically in love with her newish partner, and at long last the mother of a toddler after struggling to conceive for ten years, riding high. Suddenly in spring she was diagnosed with breast cancer.

The artist, real name J. Cornish, is known for telling it as it is. The LP, her latest release, was meant as an transparent story, addressing every bit of hardship she’d endured since she last recorded music (endometrial issues, losing a baby, failed relationships, psychological manipulation, mental health struggles) with her usual frankness. The first single, No Secrets, was launched in April. But by then there was a mighty secret. The illness. Then second single, Living My Best Life, came out in May and the artist was giving interviews about how she was living her best life, while at the same time coping with her cancer. A month later she went public, and in the start of summer she underwent breast removal surgery.

She shoots me her best “Are you kidding?” expression. “I put out with a song called the track No Secrets. I’m doing every interview, and they ask, ‘Any updates?’ and I respond, ‘Uh, nothing really’” she has just had to postpone shows because she’s yet to undergo cosmetic procedures.

We’re at a photography studio in the capital. She is wearing a light brown synthetic jacket, blue jeans with elaborate white patches, off-white boots and oversized specs. Think rocker vibe meets 1970s Nana Mouskouri. “I feel like I’m in the seventies and I should have a boyfriend with a big tache.” Like the film, I say, thinking of the film. “I was nicknamed that in school!” She beams. She is fast-thinking, irreverent and blunt. She says she has always fancied doing comedy and is aiming for her standup debut soon. “I like entertaining. On stage I frequently joke about the audience.”

Medical Challenges and Discovery

She was planning an performance at the Baftas when she found a lump. “I quickly sought to get it checked, had an ultrasound, and they said, ‘It appears fine; you’ve got really good dense breast tissue.’ And I was, like, ‘Yet I sense it. I’ve got an achy arm and numbness in my fingers whenever I wake up.’ And they suggested, ‘How about a biopsy?’ That was 28 March, the following my birthday.” It was a Friday. The physician told her if it was serious she’d call on the start of the week. By then the singer had assured herself it was okay. The way she explains it, it was just bad timing to get cancer when she had a busy schedule.

“Just two weeks before from releasing the album after a long hiatus and four years without a single. And she [the doctor] texted and said, ‘Is six okay?’ And I was, like, ‘A video call, likely minor.’ So I jump on the Zoom believing it’s all going to be good, and she goes, ‘You might want to sit.’ The solemn tone? And she reveals, ‘I’m so, so sorry but your biopsy results have shown aggressive cancer.’” What was your reaction? “I answered, ‘Well, that’s not great. What awful timing.’ My initial thought was, ‘I can’t die because my son needs me.’”

Some men find me challenging due to my self-awareness

She found the surgery terrifying and absurd. “I hate being put under. They walk you down. In urgent cases you go on a gurney, but now I just walked with a gown on and my rear exposed. It felt surreal.” But, she notes, she’s been lucky. No chemotherapy or radiation, just the op. “It’s terrible, but however Luckily it was detected early. I underwent removal four months ago and my one side now looks like a fruit under fabric.” A further beam. “The nipple was preserved.”

The next operation is both medical and cosmetic. Her chest, she observes, are now “different sizes. They didn’t do an implant as small as my original. That’s impolite! I thought, why make it worse, I’m already having a hard period. Such disrespect! Amusingly I said I’d avoid breast surgery because I’ve got obsessive tendencies, and I know they’d never be flawless. Cancer ruined that plan.”

Previous Struggles

Cornish is accustomed to medical issues. She believes her outlook on her diagnosis has been so positive because she’s used to health crises. They have often coincided with professional successes, functioning as a wake-up call, or punch in the stomach, to highlight not to take anything for granted. “Frankly, I feel life goes, ‘Enjoying yourself? Hold on.’ From a young age, it has always gone alongside high points for me; a serious or unusual issue has happened to my health.”

She recalls to her childhood, already making her debut starring in the London theater in Whistle Down the Wind (she was chosen at the age of 9). That’s when she was diagnosed with the heart condition WPW, which can cause a tachycardia as well as dizziness and heart flutters. “I rehearsed between visits on an intravenous line, and being readmitted at night.” She jumps ahead several years, and teenage Jess has joined the trio Soul Deep while enrolled in the performing arts school. “I just got my first record deal, and I had a cerebral event. Then when I was planning to release songs in the year 2020 I had a collision and my larynx moved up and I couldn’t sing for a year.”

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