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

You wouldn’t believe it, Jessie J states. At that moment preparing for her first album release in eight years, blissfully happy with her newish partner, and finally the mom to a little one after facing fertility challenges for ten years, riding high. Suddenly in spring she was found to have a breast cancer diagnosis.

The artist, birth name J. Cornish, is famous for speaking her mind. The record, her latest release, was supposed to be an candid account, dealing with every bit of hardship she’d endured since she last worked on songs (endometrial issues, miscarriage, unsuccessful partnerships, gaslighting, mental health struggles) with her usual frankness. The initial release, No Secrets, was launched in April. But by then there existed a huge secret. The cancer. 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 dealing with the disease. Subsequently she shared the news, and in early July she had a mastectomy.

She shoots me her best “Seriously?” expression. “I release with a song called the track No Secrets. I’m giving every press talk, and they ask, ‘Any updates?’ and I’m, like, ‘Erm, yeah, nothing …’” Cornish has just had to cancel tour dates because she’s awaiting follow-up surgery.

We’re at a studio in the capital. She is dressed in a light brown synthetic jacket, blue jeans with detailed white appliqués, off-white boots and oversized specs. Think motorcycle style meets vintage look. “As if I’m in the 70s and I should have a boyfriend with a big tache.” Easy Rider, I say, recalling the film. “I was nicknamed that in school!” She grins. She is sharp-witted, irreverent and filter-free. She says she has always been interested in humor and is aiming for her first comedy performance in the coming year. “I like entertaining. On stage I basically roast the fans.”

Personal Battles and News

She was getting ready for an appearance at the Baftas when she found a lump. “I promptly visited to get it looked at, had an test, and they said, ‘It looks like nothing; you’ve got really good dense breast tissue.’ And I insisted, ‘But I can feel it. I have arm pain and numbness in my fingers whenever I get up.’ And they replied, ‘Well, let’s just do a biopsy?’ The date was March 28, the following my birthday.” It was a Friday. The physician told her if it was concerning she’d call on the Monday. By then the singer had persuaded herself it was fine. The way she tells it, it was just bad timing to face illness when she had a busy schedule.

“We’re two weeks away from debuting the project after years away and no new music. And the doctor messaged and said, ‘Can you talk at six?’ And I was, like, ‘It’s virtual, probably routine.’ So I join the call believing it’s all going to be good, and she informs me, ‘You might want to sit.’ That sympathetic voice? And she continues, ‘I’m so, so sorry but your test results have indicated aggressive cancer.’” What did you say? “I said, ‘That’s unfortunate. The timing is terrible.’ Immediately I felt was, ‘My child depends on me.’”

Some men find me challenging due to my self-awareness

She viewed the procedure frightening and surreal. “I hate being put under. They lead you. You know when you have emergency surgery you are wheeled, but this time I just strolled down with a medical attire and my bum hanging out. Like a dystopian scene.” But, she notes, she’s been blessed. No chemotherapy or radiation, just the surgery. “It’s terrible, but yet Thank fuck I found it early. I had the mastectomy recently and my right breast now appears as a grapefruit under a tight bedsheet.” A further beam. “The nipple was preserved.”

The next operation is both medical and cosmetic. Her chest, she remarks, are now “asymmetrical. They didn’t do an implant as small as my original. How rude! I felt, don’t add insult to injury, 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 perfect. Cancer ruined that plan.”

Previous Struggles

The singer is familiar with health problems. She thinks her outlook on her diagnosis has been so upbeat because she’s experienced in medical emergencies. They have often coincided with peak moments, acting as a reminder, or shock, to make her recall not to be complacent. “Honestly, I feel life goes, ‘You having a good time? Sit down.’ Since childhood, it has often paired with high points for me; something severe or obscure has affected my well-being.”

She recalls to her youth, already starting her career featuring in the stage in a musical (she was cast at the age of 9). That’s when she was found to have the heart condition a syndrome, which can cause a rapid pulse as well as lightheadedness and heart flutters. “I was going in and out of rehearsals on an drip, and being readmitted at night.” She jumps ahead six years, and teenage Jess has become part of the trio Soul Deep while enrolled in the academy. “I secured a deal, and I had a stroke. Then when I was ready to debut in recently I had a car crash and my voice box shifted and I was unable to vocalize for a twelve months.”

Hey, I say, wait, I can’t keep up. A stroke so young? She nods|agrees
