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

You couldn’t make it up, Jessie J states. At that moment preparing for her first album release in eight years, blissfully happy with her newish partner, and finally the parent to a young child after facing fertility challenges for a decade, feeling invincible. Then in spring she was told she had breast cancer.

The artist, birth name Jess Cornish, is famous for being brutally honest. The album, her latest release, was supposed to be an open book, addressing every ounce of devastation she’d experienced since she last recorded music (endometriosis, pregnancy loss, unsuccessful partnerships, psychological manipulation, suicide) with characteristic openness. The initial release, her single No Secrets, was launched in the spring. But by then there existed a huge secret. Her diagnosis. Then second single, the upbeat Living My Best Life, debuted in May and Cornish was giving interviews about how she was enjoying life to the fullest, while at the same time dealing with breast cancer. Four weeks after she disclosed her condition, and in July she received surgical treatment.

She offers me her best “What the fuck?” expression. “I release with a song called the track No Secrets. I’m giving every interview, and they ask, ‘What’s happening?’ and I’m, like, ‘Well, not much…’” she has just had to call off performances because she’s yet to undergo follow-up surgery.

We’re at a studio in London. She is wearing a light brown synthetic jacket, jeans with detailed white appliqués, cream boots and oversized specs. Imagine 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, thinking of the picture. “They used to call me that!” She beams. Jessie is sharp-witted, unfiltered and filter-free. She says she has always been interested in humor and is hoping to make her first comedy performance in the coming year. “I like entertaining. When performing I basically roast the audience.”

Medical Challenges and Discovery

The artist was planning an slot at the ceremony when she discovered a mass. “I promptly visited to get it examined, had an ultrasound, and they said, ‘It appears fine; your breasts are normal.’ And I was, like, ‘Yet I sense it. My arm hurts and pins and needles in my hands whenever I wake up.’ And they replied, ‘We should biopsy it?’ It happened on March 28, the post-birthday.” It was a weekend eve. The doctor told her if it was serious she’d reach out on the start of the week. By then the singer had convinced herself it was fine. The way she describes it, it was just bad timing to receive a diagnosis when she had so much on.

“We’re two weeks away from launching this thing after years away and an extended break. And the doctor messaged and said, ‘Can you talk at six?’ And I was, like, ‘A video call, likely minor.’ So I log in expecting it’s all going to be fine, and she says, ‘Please take a seat.’ That sympathetic voice? And she says, ‘Unfortunately but your test results have shown high-grade cancer cells.’” What did you say? “I answered, ‘Oh, that’s not ideal, is it?. What awful timing.’ My initial thought was, ‘My child depends on me.’”

I’ve been labeled difficult for knowing myself

She found the surgery frightening and surreal. “I hate being put under. You’re escorted. You know when you have emergency surgery you are wheeled, but this time I just walked 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 chemotherapy or radiation, just the procedure. “Cancer sucks, man, but yet Thank fuck I found it early. I underwent removal recently and my affected breast now resembles a odd shape.” She smiles again. “I got to keep the nipple, though.”

The subsequent surgery is for health and appearance. Her breasts, she observes, are now “uneven. They didn’t do an implant as small as my original. How rude! I felt, why make it worse, I’m already having a difficult experience. So rude! It’s funny because I said I’d avoid breast surgery because I’ve got OCD, and I know they’d never be ideal. Illness changed that.”

A History of Health Challenges

The singer is no stranger to illness. She feels her outlook on her diagnosis has been so positive because she’s familiar with medical emergencies. Many times they occur alongside professional successes, serving as a tap on the shoulder, or punch in the stomach, to remind her not to take anything for granted. “Truly, I feel fate says, ‘Enjoying yourself? Take a seat.’ Since childhood, it has often paired with high points for me; a major or strange event has affected my well-being.”

She reminisces to her childhood, already starting her career featuring in the West End in Whistle Down the Wind (she was cast at the age of nine years old). That’s when she was found to have the cardiac issue WPW, which can cause a fast heartbeat as well as lightheadedness and irregular beats. “I attended rehearsals intermittently on an IV drip, and being readmitted at night.” She jumps ahead several years, and teenage Jess has joined the trio Soul Deep while attending the Brit School. “I signed my initial contract, and I had a brain incident. Then when I was ready to debut in the year 2020 I had a collision and my larynx moved up and I lost my voice for a long period.”

Wow, I say, hold on, I need a moment. You really had a stroke at 17? She nods|agrees
