‘It has taught me to embrace life more’: Jessica Cornish on her health battle, career returns and conquering the Chinese market

You wouldn’t believe it, Jessie J says. There she was readying for her new album launch in eight years, ecstatically in love with her newish partner, and at long last the mom to a little one after struggling to conceive for a decade, riding high. Then in spring she was found to have a breast cancer diagnosis.

The singer-songwriter, real name J. Cornish, is renowned for speaking her mind. The album, the provocatively titled album, was intended as an open book, addressing every bit of hardship she’d endured since she last worked on songs (endometrial issues, losing a baby, broken romances, gaslighting, mental health struggles) with typical candour. The initial release, the song No Secrets, was launched in April. But by then there remained a major undisclosed truth. Her diagnosis. Then follow-up track, her song Living My Best Life, came out in May and the artist was giving interviews about how she was living her best life, while still secretly living with the disease. A month later she disclosed her condition, and in July she received surgical treatment.

She gives me her best “What the fuck?” expression. “I come out with a song called No Secrets. I’m conducting every interview, and they ask, ‘What’s happening?’ and I answer, ‘Uh, nothing really’” Cornish has just had to postpone shows because she’s awaiting cosmetic procedures.

We’re at a photography studio in London. She is dressed in a tan faux-leather coat, denim trousers with elaborate white patches, off-white boots and oversized specs. Imagine rocker vibe meets 1970s Nana Mouskouri. “It seems like I’m in the 1970s and I should have a man with facial hair.” A biker reference, I say, thinking of the movie. “They used to call me that!” She grins. Jessie is sharp-witted, unfiltered and filter-free. She says she has always fancied doing comedy and is aiming for her initial standup show in the coming year. “I enjoy humor. When performing I frequently joke about the audience.”

Personal Battles and News

She was planning an appearance at the Baftas when she discovered a mass. “I immediately went to get it looked at, had an ultrasound, and they were, like, ‘It appears fine; you’ve got really good dense breast tissue.’ And I insisted, ‘Yet I sense it. I have arm pain and pins and needles in my hands whenever I get up.’ And they replied, ‘How about a biopsy?’ The date was March 28, the post-birthday.” It was a Friday. The specialist told her if it was bad news she’d call on the Monday. By then Cornish had assured herself it was nothing. The way she tells it, it was inopportune to receive a diagnosis when she had many commitments.

“Just two weeks before from releasing the album after a long hiatus and four years without a single. And the doctor messaged and said, ‘Can you talk at six?’ And I assumed, ‘Oh, it’s a Zoom, it won’t be anything.’ So I jump on the Zoom expecting it’s all going to be positive, and she goes, ‘You might want to sit.’ You know that sad tone they use? And she says, ‘Unfortunately but your reports have come back as aggressive cancer.’” What was your reaction? “I replied, ‘Oh, that’s not ideal, is it?. The timing is terrible.’ My initial thought was, ‘I can’t die because my son needs me.’”

Some men find me challenging due to my self-awareness

She viewed the procedure terrifying and absurd. “I fear going under. You’re escorted. You know when you have emergency surgery you go on a gurney, but now I just walked with a medical attire and my rear exposed. Like a dystopian scene.” But, she adds, she’s been lucky. Without chemo or radio, just the procedure. “It’s terrible, but yet Luckily it was detected early. I underwent removal a few months back and my one side now appears as a grapefruit under a tight bedsheet.” A further beam. “The nipple was preserved.”

The subsequent surgery is both medical and cosmetic. Her boobs, she notes, are now “asymmetrical. The implant is larger than before. How rude! I thought, why make it worse, I’m already having a difficult experience. Such disrespect! Ironically I said I’d not undergo augmentation because I’ve got perfectionism, and I know they’d never be flawless. Cancer ruined that plan.”

Past Medical Issues

Cornish is accustomed to medical issues. She believes her attitude toward illness has been so positive because she’s experienced in physical challenges. They have often coincided with peak moments, serving as a tap on the shoulder, or blow, to highlight not to take anything for granted. “Truly, I feel fate says, ‘Enjoying yourself? Sit down.’ From a young age, it has often paired with achievements for me; something severe or obscure has impacted my body.”

She recalls to her 11-year-old self, already making her debut starring in the London theater in a musical (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 rapid pulse as well as lightheadedness and irregular beats. “I rehearsed between visits on an intravenous line, and returning to the hospital at night.” She fast-forwards half a dozen years, and young Jessica has joined the trio Soul Deep while enrolled in the performing arts school. “I just got my first record deal, and I had a cerebral event. Then when I was about to put out music in the year 2020 I had a car crash and my larynx moved up and I lost my voice for a twelve months.”

Hey, I say, wait, I am overwhelmed. At just 17? She nods|agrees
