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

You couldn’t make it up, the singer says. At that moment preparing for her comeback record in eight years, blissfully happy with her recent boyfriend, and at long last the parent to a young child after struggling to conceive for ten years, riding high. Then in spring she was told she had breast cancer.

The singer-songwriter, real name J. Cornish, is renowned for speaking her mind. The LP, Don’t Tease Me With a Good Time, was supposed to be an open book, addressing every moment of pain she’d experienced since she last recorded music (endometrial issues, miscarriage, unsuccessful partnerships, psychological manipulation, suicidal thoughts) with her usual frankness. The initial release, her single No Secrets, was launched in the spring. But by then there was a mighty secret. Her diagnosis. Then next release, the upbeat Living My Best Life, came out in late spring and the artist was speaking publicly about how she was enjoying life to the fullest, while at the same time living with breast cancer. A month later she disclosed her condition, and in July she received surgical treatment.

She gives me her best “What the fuck?” expression. “I put out with a song called the track No Secrets. I’m conducting every press talk, and they ask, ‘What’s happening?’ and I’m, like, ‘Well, not much…’” Cornish has just had to call off performances because she’s awaiting reconstructive surgery.

We’re at a studio in London. She is dressed in a tan faux-leather coat, denim trousers with elaborate white patches, beige footwear and oversized specs. Picture biker chic meets vintage look. “It seems like I’m in the 1970s and I should have a boyfriend with a big tache.” A biker reference, I say, thinking of the movie. “I was nicknamed that in school!” She beams. Cornish is fast-thinking, unfiltered and filter-free. She says she has always been interested in humor and is hoping to make her first comedy performance next year. “I enjoy humor. During performances I often tease the crowd.”

Medical Challenges and Discovery

She was preparing for an appearance at the Baftas when she discovered a mass. “I immediately went to get it examined, had an ultrasound, and they were, like, ‘It looks like nothing; your breasts are normal.’ And I responded, ‘Yet I sense it. I’ve got an achy arm and tingling in my hands whenever I rise.’ And they suggested, ‘We should biopsy it?’ That was 28 March, the day after my birthday.” It was a Friday. The doctor told her if it was serious she’d reach out on the Monday. By then the singer had convinced herself it was okay. The way she tells it, it was just bad timing to face illness when she had so much on.

“Just two weeks before from launching this thing after a long hiatus and an extended break. And she [the doctor] texted and said, ‘Can you talk at six?’ And I was, like, ‘Oh, it’s a Zoom, it won’t be anything.’ So I jump on the Zoom believing it’s all going to be positive, and she goes, ‘Are you sitting down?.’ You know that sad tone they use? And she says, ‘I’m so, so sorry but your test results have shown aggressive cancer.’” How did you respond? “I answered, ‘Well, that’s not great. The timing is terrible.’ The first thing I thought was, ‘I have to survive for my boy.’”

I’ve been labeled difficult for knowing myself

She found the surgery scary and bizarre. “I dislike anesthesia. They lead you. During crises you go on a gurney, but this time I just walked with a hospital gown and my rear exposed. You feel like you’re in an episode of Black Mirror.” But, she notes, she’s been blessed. Without chemo or radio, just the surgery. “It’s terrible, but you know what? Luckily it was detected early. I underwent removal four months ago and my one side now looks like a fruit under fabric.” Another grin. “I got to keep the nipple, though.”

The subsequent surgery is for health and appearance. Her boobs, she remarks, are now “uneven. The implant is larger than before. How rude! I thought, no need to bully me, I’m already having a rough time. Such disrespect! Amusingly I said I’d never get my boobs done because I’ve got obsessive tendencies, and I know they’d never be flawless. Illness changed that.”

A History of Health Challenges

Cornish is familiar with health problems. She believes her attitude toward illness has been so positive because she’s used to health crises. Many times they occur alongside career highs, acting as a reminder, or shock, to make her recall not to be complacent. “Frankly, I feel the universe whispers, ‘Things going well? Sit down.’ From a young age, it has consistently accompanied high points for me; a serious or unusual issue has happened to my health.”

She takes me back to her youth, already making her debut starring in the West End in a musical (she was chosen at the age of nine). That’s when she was found to have the heart condition WPW, which can cause a fast heartbeat as well as vertigo and irregular beats. “I attended rehearsals intermittently on an intravenous line, and being readmitted at night.” She jumps ahead several years, and teenage Jess has become part of the female band Soul Deep while attending the performing arts school. “I signed my initial contract, and I had a brain incident. Then when I was ready to debut in the year 2020 I had a collision and my voice box shifted and I was unable to vocalize for a year.”

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