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

You wouldn’t believe it, the singer states. There she was readying for her first album release in eight years, deeply enamored with her newish partner, and finally the mother of a toddler after facing fertility challenges for a decade, feeling invincible. Then in spring she was found to have breast cancer.

The musician, birth name J. Cornish, is known for being brutally honest. The LP, Don’t Tease Me With a Good Time, was supposed to be an transparent story, tackling every ounce of devastation she’d experienced since she last worked on songs (a gynecological condition, miscarriage, failed relationships, emotional abuse, suicide) with typical candour. The lead track, the song No Secrets, was launched in the spring. But by then there existed a huge secret. Her diagnosis. Later follow-up track, her song Living My Best Life, debuted in late spring and Cornish was talking to press about how she was enjoying life to the fullest, while all the while coping with her cancer. Subsequently she disclosed her condition, and in July she had a mastectomy.

She offers me her best “Are you kidding?” look. “I come out with a song called the track No Secrets. I’m giving every press talk, and they ask, ‘Any updates?’ and I’m, like, ‘Well, not much…’” Cornish has just had to postpone shows because she’s still waiting for cosmetic procedures.

Our interview takes place at a studio in the capital. She is dressed in a beige fake-leather jacket, blue jeans with elaborate white patches, off-white boots and large glasses. Think rocker vibe meets vintage look. “It seems like I’m in the seventies and I should have a boyfriend with a big tache.” Like the film, I say, thinking of the movie. “That’s what people called me at school!” She grins. Cornish is quick, irreverent and direct. She says she has always fancied doing comedy and is planning to attempt her first comedy performance soon. “I like entertaining. During performances I basically roast the fans.”

Health Struggles and Diagnosis

The artist was planning an slot at the ceremony when she discovered a mass. “I promptly visited to get it looked at, had an ultrasound, and they told me, ‘It looks like nothing; you’ve got really good dense breast tissue.’ And I insisted, ‘But I can feel it. I’ve got an achy arm and numbness in my fingers whenever I wake up.’ And they suggested, ‘Well, let’s just do a biopsy?’ The date was March 28, the following my birthday.” It was a weekend eve. The specialist told her if it was concerning she’d reach out on the Monday. By then the singer had assured herself it was fine. The way she describes it, it was simply too inconvenient to get cancer when she had many commitments.

“It was a fortnight prior from debuting the project after a long hiatus and no new music. And the doctor messaged and said, ‘Can you talk at six?’ And I thought, ‘A video call, likely minor.’ So I log in believing it’s all going to be positive, and she says, ‘Please take a seat.’ That sympathetic voice? And she reveals, ‘I regret to inform you but your test results have shown high-grade cancer cells.’” What was your reaction? “I replied, ‘That’s unfortunate. The timing is terrible.’ Immediately I felt was, ‘I can’t die because my son needs me.’”

Some men find me challenging due to my self-awareness

She viewed the procedure frightening and surreal. “I fear going under. You’re escorted. You know when you have emergency surgery you roll down in a bed, but this time I just marched with a medical attire and my backside out. Like a dystopian scene.” But, Cornish says, she’s been fortunate. No chemo, no radiotherapy, just the op. “Cancer is awful, but however Luckily it was detected early. I had the mastectomy recently and my one side now resembles a fruit under fabric.” Another grin. “The nipple was preserved.”

The subsequent surgery is for health and appearance. Her chest, she remarks, are now “different sizes. The size doesn’t match. That’s impolite! I thought, 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 flawless. Cancer ruined that plan.”

A History of Health Challenges

She is familiar with health problems. She believes her outlook on her diagnosis has been so optimistic because she’s experienced in health crises. Frequently they align with peak moments, functioning as a wake-up call, or shock, to highlight not to be complacent. “Honestly, I feel life goes, ‘You having a good time? Sit down.’ From a young age, it has often paired with achievements for me; a serious or unusual issue has affected my well-being.”

She takes me back to her childhood, already beginning starring in the West End in Whistle Down the Wind (she was chosen at the age of nine). That’s when she was found to have the heart condition Wolff-Parkinson-White syndrome, which can cause a tachycardia as well as lightheadedness and heart flutters. “I attended rehearsals intermittently on an IV drip, and going back into hospital at night.” She skips forward six years, and young Jessica has entered the female band the group while enrolled in the Brit School. “I just got my first record deal, and I had a stroke. Then when I was planning to release songs in 2020 I had a car crash and my voice box shifted and I couldn’t sing for a twelve months.”

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