‘It has pushed me to live more fully’: Jessie J on cancer, career returns and cracking China

You wouldn’t believe it, the singer says. There she was preparing for her new album launch in eight years, ecstatically in love with her recent boyfriend, and at long last the mother of a toddler after struggling to conceive for ten years, on top of the world. Suddenly in spring she was found to have a breast cancer diagnosis.

The artist, actual name Jess Cornish, is renowned for being brutally honest. The LP, the provocatively titled album, was supposed to be an candid account, dealing with every bit of hardship she’d faced since she last worked on songs (a gynecological condition, miscarriage, broken romances, emotional abuse, suicidal thoughts) with her usual frankness. The first single, the song No Secrets, was launched in April. But by then there existed a huge secret. Her diagnosis. Then next release, Living My Best Life, debuted in late spring and she was giving interviews about how she was thriving, while at the same time living with the disease. Subsequently she disclosed her condition, and in early July she underwent breast removal surgery.

She offers me her best “Are you kidding?” look. “I put out with a song called the track No Secrets. I’m doing every press talk, and they ask, ‘Any updates?’ and I respond, ‘Well, not much…’” the singer has just had to call off performances because she’s awaiting cosmetic procedures.

Our interview takes place at a photography studio in London. She is sporting a light brown synthetic jacket, blue jeans with ornate white designs, off-white boots and oversized specs. Imagine rocker vibe meets vintage look. “I feel like I’m in the 1970s and I should have a partner with a mustache.” A biker reference, I say, recalling the picture. “That’s what people called me at school!” She smiles. Jessie is fast-thinking, irreverent and direct. She says she has always fancied doing comedy and is aiming for her standup debut in the coming year. “I enjoy humor. During performances I basically roast the audience.”

Health Struggles and Diagnosis

Cornish was getting ready for an slot at the Baftas when she discovered a mass. “I quickly sought to get it checked, had an scan, and they told me, ‘It seems benign; you’ve got really good dense breast tissue.’ And I was, like, ‘Yet I sense it. I have arm pain and tingling in my hands whenever I wake up.’ And they said, ‘We should biopsy it?’ The date was March 28, the following my birthday.” It was a Friday. The doctor told her if it was concerning 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 simply too inconvenient to face illness when she had so much on.

“It was a fortnight prior from launching this thing after eight years without an album and no new music. And she contacted me and said, ‘Are you free at six?’ And I was, like, ‘A video call, likely minor.’ So I log in believing it’s all going to be positive, and she goes, ‘Are you sitting down?.’ The solemn tone? And she continues, ‘I regret to inform you but your test results have shown aggressive cancer.’” How did you respond? “I replied, ‘Oh, that’s not ideal, is it?. What awful timing.’ Immediately I felt was, ‘My child depends on me.’”

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

She viewed the procedure frightening and surreal. “I fear going under. You’re escorted. During crises you go on a gurney, but this time I just marched with a gown on and my backside out. You feel like you’re in an episode of Black Mirror.” But, she notes, she’s been fortunate. No chemotherapy or radiation, just the surgery. “It’s terrible, but yet I’m grateful it was caught soon. The surgery happened recently and my affected breast now resembles a grapefruit under a tight bedsheet.” She smiles again. “I got to keep the nipple, though.”

The next operation is for health and appearance. Her chest, she notes, are now “asymmetrical. The implant is larger than before. So inconsiderate! 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 perfectionism, and I know they’d never be ideal. Illness changed that.”

Previous Struggles

Cornish is familiar with health problems. She thinks her outlook on her diagnosis has been so optimistic because she’s familiar with health crises. Frequently they align with career highs, functioning as a wake-up call, or punch in the stomach, to highlight not to be complacent. “Honestly, I feel the universe whispers, ‘Things going well? Take a seat.’ From a young age, it has often paired with high points for me; a serious or unusual issue has affected my well-being.”

She recalls to her 11-year-old self, already beginning starring in the London theater in Whistle Down the Wind (she was selected at the age of 9). That’s when she was told about the medical problem WPW, which can cause a tachycardia as well as dizziness and irregular beats. “I was going in and out of rehearsals on an intravenous line, and returning to the hospital at night.” She jumps ahead six years, and 17-year-old Jess has joined the female band Soul Deep while studying at the academy. “I secured a deal, and I had a brain incident. Then when I was planning to release songs in 2020 I had a car crash and my larynx moved up and I lost my voice for a twelve months.”

Oi, I say, hold on, I am overwhelmed. At just 17? She nods|agrees
