‘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. At that moment preparing for her first album release in eight years, blissfully happy with her current love, and finally the mom to a little one after struggling to conceive for a decade, on top of the world. Suddenly in spring she was found to have a breast cancer diagnosis.

The musician, birth name Jess Cornish, is famous for speaking her mind. The album, the provocatively titled album, was meant as an candid account, addressing every ounce of devastation she’d endured since she last recorded music (endometriosis, pregnancy loss, unsuccessful partnerships, psychological manipulation, suicide) with typical candour. The lead track, the song No Secrets, was released in the spring. But by then there existed a huge secret. The cancer. Then next release, the upbeat Living My Best Life, was released in late spring and she was talking to press about how she was living her best life, while still secretly living with the disease. A month later she disclosed her condition, and in early July she had a mastectomy.

She shoots me her best “Are you kidding?” look. “I come out with a song called No Secrets. I’m conducting every interview, and they ask, ‘Any updates?’ and I answer, ‘Erm, yeah, nothing …’” the singer has just had to cancel tour dates because she’s yet to undergo reconstructive surgery.

We meet at a photography studio in London. She is dressed in a light brown synthetic jacket, denim trousers with detailed white appliqués, cream boots and oversized specs. Imagine biker chic meets vintage look. “I feel like I’m in the 70s and I should have a partner with a mustache.” Easy Rider, I say, referencing the movie. “That’s what people called me at school!” She grins. Cornish is quick, bold and filter-free. She says she has always wanted to try comedy and is planning to attempt her initial standup show next year. “I enjoy humor. On stage I frequently joke about the crowd.”

Health Struggles and Diagnosis

The artist was preparing for an slot at the awards show when she noticed an abnormality. “I immediately went to get it examined, had an test, and they told me, ‘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 replied, ‘How about a biopsy?’ That was 28 March, the following my birthday.” It was a Friday. The specialist told her if it was concerning she’d contact on the Monday. By then she had convinced herself it was nothing. The way she describes it, it was inopportune to face illness when she had a busy schedule.

“Just two weeks before from launching this thing after eight years without an album and four years without a single. And the doctor messaged and said, ‘Are you free at six?’ And I thought, ‘A video call, likely minor.’ So I jump on the Zoom thinking it’s all going to be positive, and she says, ‘You might want to sit.’ The solemn tone? And she continues, ‘I’m so, so sorry but your test results have come back as aggressive cancer.’” What did you say? “I said, ‘Oh, that’s not ideal, is it?. What awful timing.’ My initial thought was, ‘I have to survive for my boy.’”

Some men find me challenging due to my self-awareness

She considered the operation scary and bizarre. “I hate being put under. They lead you. In urgent cases you roll down in a bed, but this time I just marched with a medical attire and my rear exposed. It felt surreal.” But, she adds, she’s been fortunate. No chemo, no radiotherapy, just the surgery. “Cancer sucks, man, but yet I’m grateful it was caught soon. I had the mastectomy four months ago and my affected breast now looks like a fruit under fabric.” She smiles again. “I got to keep the nipple, though.”

The next operation is for health and appearance. Her breasts, she observes, are now “different sizes. The implant is larger than before. How rude! I thought, no need to bully me, I’m already having a rough time. Such disrespect! Ironically I said I’d not undergo augmentation because I’ve got OCD, and I know they’d never be flawless. My plans were disrupted.”

Previous Struggles

The singer is no stranger to illness. She thinks her attitude toward illness has been so upbeat because she’s experienced in physical challenges. They have often coincided with professional successes, acting as a reminder, or punch in the stomach, to make her recall not to take anything for granted. “Truly, I feel fate says, ‘You having a good time? Hold on.’ Since childhood, it has consistently accompanied high points for me; a major or strange event has impacted my body.”

She takes me back to her childhood, already beginning starring in the London theater in a musical (she was chosen at the age of 9). That’s when she was found to have the heart condition a syndrome, which can cause a fast heartbeat as well as dizziness and palpitations. “I was going in and out of rehearsals on an drip, and going back into hospital at night.” She fast-forwards several years, and 17-year-old Jess has entered the female band Soul Deep while enrolled in the academy. “I signed my initial contract, and I had a cerebral event. Then when I was planning to release songs in the year 2020 I had a automobile accident and my larynx moved up and I couldn’t sing for a long period.”

Oi, I say, slow down, I am overwhelmed. At just 17? She nods|agrees
