‘It has made me live 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 gearing up for her comeback record in nearly a decade, deeply enamored with her current love, and at long last the parent to a young child after dealing with conception issues for ten years, on top of the world. Then in spring she was told she had breast cancer.

The musician, birth name J. Cornish, is renowned for telling it as it is. The album, her latest release, was meant as an transparent story, tackling every ounce of devastation she’d experienced since she last recorded music (endometriosis, miscarriage, unsuccessful partnerships, emotional abuse, mental health struggles) with her usual frankness. The first single, the song No Secrets, was dropped in April. But by then there remained a major undisclosed truth. The illness. Then second single, the upbeat Living My Best Life, came out in late spring and the artist was talking to press about how she was enjoying life to the fullest, while at the same time living with her cancer. Subsequently she went public, and in July she received surgical treatment.

She shoots me her best “What the fuck?” look. “I come out with a song called No Secrets. I’m doing every press talk, and they inquire, ‘Any updates?’ and I respond, ‘Well, not much…’” she has just had to cancel tour dates because she’s still waiting for reconstructive surgery.

We meet at a photography studio in London. She is sporting a beige fake-leather jacket, denim trousers with detailed white appliqués, off-white boots and oversized specs. Picture biker chic meets 1970s Nana Mouskouri. “I feel like I’m in the 1970s and I should have a partner with a mustache.” Like the film, I say, recalling the film. “They used to call me that!” She beams. Jessie is quick, unfiltered and direct. She says she has always fancied doing comedy and is planning to attempt her initial standup show next year. “I like entertaining. On stage I frequently joke about the fans.”

Medical Challenges and Discovery

She was planning an performance at the awards show when she discovered a mass. “I quickly sought to get it checked, had an scan, and they were, like, ‘It seems benign; your breasts are normal.’ And I insisted, ‘Yet I sense it. I have arm pain and numbness in my fingers whenever I rise.’ And they said, ‘We should biopsy it?’ That was 28 March, the following my birthday.” It was a weekend eve. The physician told her if it was concerning she’d reach out on the start of the week. By then she had assured herself it was fine. The way she describes it, it was inopportune to face illness when she had a busy schedule.

“We’re two weeks away from releasing the album after eight years without an album and no new music. And she contacted me and said, ‘Is six okay?’ And I was, like, ‘It’s virtual, probably routine.’ So I join the call expecting it’s all going to be good, and she goes, ‘Please take a seat.’ That sympathetic voice? And she reveals, ‘I’m so, so sorry but your test results have shown malignant cells.’” What did you say? “I replied, ‘Well, that’s not great. That’s not fucking great timing.’ My initial thought was, ‘I have to survive for my boy.’”

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

She viewed the procedure terrifying and absurd. “I hate being put under. They walk you down. In urgent cases you are wheeled, but then I just walked with a medical attire and my bum hanging out. Like a dystopian scene.” But, she adds, she’s been blessed. No chemo, no radiotherapy, just the surgery. “Cancer sucks, man, but you know what? Thank fuck I found it early. I underwent removal a few months back and my one side now looks like a grapefruit under a tight bedsheet.” A further beam. “At least the nipple remains.”

The subsequent surgery is therapeutic and aesthetic. Her breasts, she remarks, are now “asymmetrical. The size doesn’t match. So inconsiderate! I thought, why make it worse, I’m already having a rough time. Such disrespect! Amusingly I said I’d avoid breast surgery because I’ve got obsessive tendencies, and I know they’d never be perfect. My plans were disrupted.”

A History of Health Challenges

Cornish is no stranger to illness. She thinks her attitude toward illness has been so positive because she’s experienced in physical challenges. Many times they occur alongside career highs, acting as a reminder, or punch in the stomach, to remind her not to be complacent. “Truly, I feel the universe whispers, ‘Enjoying yourself? Hold on.’ From a young age, it has often paired with high points for me; something severe or obscure has happened to my health.”

She takes me back to her childhood, already making her debut performing in the London theater in Whistle Down the Wind (she was cast at the age of nine). That’s when she was diagnosed with the cardiac issue Wolff-Parkinson-White syndrome, which can cause a fast heartbeat as well as dizziness and heart flutters. “I attended rehearsals intermittently on an drip, and going back into hospital at night.” She jumps ahead six years, and teenage Jess has entered the girl group 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 ready to debut in the year 2020 I had a car crash and my throat was injured and I lost my voice for a long period.”

Hey, I say, slow down, I am overwhelmed. A stroke so young? She nods|agrees
