‘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 says. At that moment gearing up for her comeback record in nearly a decade, blissfully happy with her recent boyfriend, and finally the parent to a young child after dealing with conception issues for a decade, riding high. Then in spring she was told she had breast cancer.

The artist, birth name Jess Cornish, is renowned for speaking her mind. The LP, her latest release, was supposed to be an candid account, tackling every ounce of devastation she’d experienced since she last recorded music (a gynecological condition, miscarriage, failed relationships, psychological manipulation, suicidal thoughts) with typical candour. The initial release, her single No Secrets, was launched in the spring. But by then there remained a major undisclosed truth. The cancer. Then second single, her song Living My Best Life, debuted in May and Cornish was talking to press about how she was living her best life, while still secretly dealing with her cancer. Four weeks after she shared the news, and in July she had a mastectomy.

She offers me her best “Are you kidding?” glance. “I come out with a song called No Secrets. I’m conducting every interview, and they’re, like, ‘What’s happening?’ and I respond, ‘Uh, nothing really’” Cornish has just had to call off performances because she’s still waiting for cosmetic procedures.

We’re at a photography studio in the capital. She is dressed in a tan faux-leather coat, jeans with detailed white appliqués, off-white boots and oversized specs. Imagine biker chic meets vintage look. “It seems like I’m in the 1970s and I should have a partner with a mustache.” Like the film, I say, thinking of the picture. “That’s what people called me at school!” She smiles. Jessie is fast-thinking, unfiltered and blunt. She says she has always been interested in humor and is aiming for her standup debut in the coming year. “I love making people laugh. On stage I often tease the fans.”

Health Struggles and Diagnosis

The artist was planning an slot at the awards show when she found a lump. “I quickly sought to get it looked at, had an ultrasound, and they were, like, ‘It appears fine; your tissue is healthy.’ And I responded, ‘But I can feel it. I’ve got an achy arm and numbness in my fingers whenever I get up.’ And they suggested, ‘How about a biopsy?’ The date was March 28, the following my birthday.” It was a Friday. The specialist told her if it was concerning she’d call on the Monday. By then she had assured herself it was nothing. The way she explains it, it was inopportune to get cancer when she had many commitments.

“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, ‘Is six okay?’ And I was, like, ‘A video call, likely minor.’ So I log in believing it’s all going to be positive, and she informs me, ‘Please take a seat.’ That sympathetic voice? And she continues, ‘I regret to inform you but your test results have indicated aggressive cancer.’” What was your reaction? “I replied, ‘Oh, that’s not ideal, is it?. What awful timing.’ The first thing I thought was, ‘My child depends on me.’”

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

She found the surgery frightening and surreal. “I hate being put under. They walk you down. During crises you go on a gurney, but now I just strolled down with a hospital gown and my bum hanging out. You feel like you’re in an episode of Black Mirror.” But, she notes, she’s been blessed. No chemo, no radiotherapy, just the procedure. “Cancer is awful, but however I’m grateful it was caught soon. The surgery happened recently and my one side now looks like a fruit under fabric.” A further beam. “At least the nipple remains.”

The next operation is both medical and cosmetic. Her boobs, she notes, are now “asymmetrical. The implant is larger than before. So inconsiderate! I felt, no need to bully me, I’m already having a difficult experience. So rude! Amusingly I said I’d not undergo augmentation because I’ve got perfectionism, and I know they’d never be perfect. My plans were disrupted.”

Previous Struggles

Cornish is no stranger to illness. She thinks her attitude toward illness has been so optimistic because she’s used to medical emergencies. Many times they occur alongside professional successes, functioning as a wake-up call, or punch in the stomach, to make her recall not to assume everything is fine. “Truly, I feel fate says, ‘Enjoying yourself? Take a seat.’ From a young age, it has often paired with achievements for me; something severe or obscure has affected my well-being.”

She takes me back to her childhood, already beginning performing in the London theater in a musical (she was selected at the age of nine years old). That’s when she was told about the heart condition a syndrome, which can cause a rapid pulse as well as lightheadedness and heart flutters. “I attended rehearsals intermittently on an drip, and being readmitted at night.” She fast-forwards half a dozen years, and young Jessica has entered the female band Soul Deep while attending the Brit School. “I just got my first record deal, and I had a cerebral event. Then when I was ready to debut in 2020 I had a car crash and my voice box shifted and I was unable to vocalize for a long period.”

Wow, I say, slow down, I am overwhelmed. You really had a stroke at 17? She nods|agrees
