‘It has pushed me to live more fully’: Jessie J on cancer, comebacks and conquering the Chinese market

You wouldn’t believe it, Jessie J says. At that moment readying for her comeback record in eight years, ecstatically in love with her current love, and finally the mother of a toddler after dealing with conception issues for a decade, on top of the world. Then in March she was found to have breast cancer.

The artist, actual name Jessica Cornish, is famous for being brutally honest. The album, her latest release, was intended as an transparent story, dealing with every ounce of devastation she’d experienced since she last worked on songs (a gynecological condition, miscarriage, unsuccessful partnerships, psychological manipulation, suicidal thoughts) with her usual frankness. The lead track, the song No Secrets, was launched in the spring. But by then there remained a major undisclosed truth. The illness. Later second single, the upbeat Living My Best Life, was released in late spring and the artist was talking to press about how she was thriving, while still secretly living with her cancer. Subsequently she shared the news, and in early July she had a mastectomy.

She shoots me her best “Are you kidding?” expression. “I put out with a song called No Secrets. I’m conducting every press talk, and they ask, ‘What’s happening?’ and I respond, ‘Well, not much…’” Cornish has just had to call off performances because she’s awaiting follow-up surgery.

We meet at a photography studio in London. She is wearing a tan faux-leather coat, jeans with ornate white designs, cream boots and large glasses. Picture motorcycle style meets 70s singer aesthetic. “I feel like I’m in the 1970s and I should have a partner with a mustache.” A biker reference, I say, thinking of the film. “That’s what people called me at school!” She smiles. She is sharp-witted, irreverent and direct. She says she has always fancied doing comedy and is planning to attempt her initial standup show next year. “I enjoy humor. On stage I basically roast the crowd.”

Health Struggles and Diagnosis

She was planning an appearance at the awards show when she discovered a mass. “I promptly visited to get it looked at, had an ultrasound, and they told me, ‘It appears fine; your breasts are normal.’ And I insisted, ‘However, it’s there. I have arm pain and numbness in my fingers whenever I wake up.’ And they said, ‘We should biopsy it?’ It happened on March 28, the day after my birthday.” It was a Friday. The physician told her if it was serious she’d reach out on the start of the week. By then she had convinced herself it was okay. The way she describes it, it was inopportune to face illness when she had so much on.

“It was a fortnight prior from debuting the project after eight years without an album and an extended break. And she [the doctor] texted and said, ‘Are you free at six?’ And I thought, ‘It’s virtual, probably routine.’ So I log in thinking it’s all going to be positive, and she informs me, ‘Are you sitting down?.’ The solemn tone? And she reveals, ‘I’m so, so sorry but your reports have come back as malignant cells.’” What was your reaction? “I replied, ‘That’s unfortunate. That’s not fucking great timing.’ The first thing I thought was, ‘My child depends on me.’”

I’ve been labeled difficult for knowing myself

She viewed the procedure terrifying and absurd. “I fear going under. They walk you down. In urgent cases you are wheeled, but this time I just strolled down with a gown on and my backside out. You feel like you’re in an episode of Black Mirror.” But, Cornish says, she’s been blessed. Without chemo or radio, just the op. “Cancer sucks, man, but however I’m grateful it was caught soon. I underwent removal a few months back and my one side now resembles a fruit under fabric.” A further beam. “I got to keep the nipple, though.”

The next operation is for health and appearance. Her chest, she notes, are now “uneven. The implant is larger than before. So inconsiderate! I felt, no need to bully me, I’m already having a difficult experience. How offensive! 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 no stranger to illness. She believes her outlook on her diagnosis has been so optimistic because she’s experienced in health crises. Frequently they align with professional successes, functioning as a wake-up call, or blow, to make her recall not to assume everything is fine. “Frankly, I feel the universe whispers, ‘Enjoying yourself? Sit down.’ From a young age, it has often paired with high points for me; a major or strange event has happened to my health.”

She recalls to her 11-year-old self, already starting her career performing in the London theater in Whistle Down the Wind (she was selected at the age of nine). That’s when she was found to have the cardiac issue a syndrome, which can cause a fast heartbeat as well as vertigo and irregular beats. “I rehearsed between visits on an drip, and returning to the hospital at night.” She jumps ahead six years, and 17-year-old Jess has become part of the trio the group while studying at the performing arts school. “I signed my initial contract, and I had a brain incident. Then when I was planning to release songs in the year 2020 I had a automobile accident and my larynx moved up and I lost my voice for a year.”

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