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

You couldn’t make it up, Jessie J states. At that moment gearing up for her comeback record in eight years, ecstatically in love with her recent boyfriend, and at long last the parent to a young child after facing fertility challenges for a decade, feeling invincible. Then in March she was told she had a breast cancer diagnosis.

The artist, real name J. Cornish, is known for speaking her mind. The LP, her latest release, was supposed to be an transparent story, tackling every ounce of devastation she’d endured since she last recorded music (endometriosis, losing a baby, unsuccessful partnerships, emotional abuse, suicide) with typical candour. The lead track, her single No Secrets, was dropped in the spring. But by then there existed a huge secret. Her diagnosis. Then second single, the upbeat Living My Best Life, came out in May and she was giving interviews about how she was enjoying life to the fullest, while all the while dealing with breast cancer. Four weeks after she went public, and in early July she received surgical treatment.

She gives me her best “Seriously?” look. “I release with a song called No Secrets. I’m conducting every press talk, and they ask, ‘Any updates?’ and I respond, ‘Well, not much…’” the singer has just had to postpone shows because she’s awaiting reconstructive surgery.

We meet at a photography studio in the capital. She is sporting a light brown synthetic jacket, jeans with elaborate white patches, beige footwear and large glasses. Imagine motorcycle style meets vintage look. “I feel like I’m in the seventies and I should have a man with facial hair.” A biker reference, I say, referencing the picture. “They used to call me that!” She beams. Jessie is fast-thinking, irreverent and filter-free. She says she has always fancied doing comedy and is planning to attempt her first comedy performance soon. “I love making people laugh. On stage I frequently joke about the audience.”

Medical Challenges and Discovery

Cornish was preparing for an slot at the awards show when she noticed an abnormality. “I promptly visited to get it examined, had an ultrasound, and they told me, ‘It seems benign; your breasts are normal.’ And I insisted, ‘But I can feel it. I’ve got an achy arm and numbness in my fingers whenever I get up.’ And they said, ‘How about a biopsy?’ It happened on March 28, the post-birthday.” It was a weekend eve. The doctor told her if it was bad news she’d reach out on the start of the week. By then she had convinced herself it was fine. The way she tells it, it was inopportune to receive a diagnosis when she had so much on.

“We’re two weeks away from releasing the album after a long hiatus and an extended break. And she [the doctor] texted and said, ‘Can you talk at six?’ And I was, like, ‘It’s virtual, probably routine.’ So I log in expecting it’s all going to be good, and she says, ‘Please take a seat.’ You know that sad tone they use? And she says, ‘I’m so, so sorry but your biopsy results have indicated high-grade cancer cells.’” What was your reaction? “I said, ‘Well, that’s not great. What awful timing.’ The first thing I thought was, ‘My child depends on me.’”

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

She found the surgery terrifying and absurd. “I fear going under. They lead you. During crises you roll down in a bed, but this time I just walked with a gown on and my rear exposed. You feel like you’re in an episode of Black Mirror.” But, she adds, she’s been lucky. Without chemo or radio, just the surgery. “Cancer is awful, but however Luckily it was detected early. I had the mastectomy a few months back and my right breast now looks like a odd shape.” A further beam. “At least the nipple remains.”

The follow-up procedure is both medical and cosmetic. Her chest, she notes, are now “different sizes. The size doesn’t match. That’s impolite! I felt, no need to bully me, I’m already having a difficult experience. So rude! Ironically I said I’d not undergo augmentation because I’ve got OCD, and I know they’d never be perfect. Illness changed that.”

A History of Health Challenges

The singer is familiar with health problems. She feels her perspective on the cancer has been so positive because she’s familiar with medical emergencies. Frequently they align with peak moments, serving as a tap on the shoulder, or punch in the stomach, to remind her not to be complacent. “Frankly, I feel life goes, ‘Enjoying yourself? Take a seat.’ Ever since I was a child, it has consistently accompanied moments of success for me; something severe or obscure has affected my well-being.”

She recalls to her youth, already starting her career performing in the West End in a musical (she was chosen at the age of nine years old). That’s when she was diagnosed with the heart condition WPW, which can cause a fast heartbeat as well as vertigo and irregular beats. “I rehearsed between visits on an IV drip, and being readmitted at night.” She jumps ahead several years, and 17-year-old Jess has become part of the female band 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 collision and my throat was injured and I was unable to vocalize for a twelve months.”

Oi, I say, hold on, I need a moment. At just 17? She nods|agrees
