‘It has taught me to embrace life more’: Jessica Cornish on her health battle, career returns and cracking China

You wouldn’t believe it, Jessie J remarks. There she was gearing up for her first album release in nearly a decade, ecstatically in love with her newish partner, and finally the mother of a toddler after facing fertility challenges for a decade, riding high. Then in March she was found to have breast cancer.

The musician, birth name J. Cornish, is known for speaking her mind. The album, Don’t Tease Me With a Good Time, was intended as an open book, dealing with every ounce of devastation she’d endured since she last made an album (endometriosis, pregnancy loss, broken romances, psychological manipulation, suicidal thoughts) with typical candour. The first single, the song No Secrets, was released in April. But by then there was a mighty secret. The cancer. Later second single, her song Living My Best Life, came out in late spring and the artist was giving interviews about how she was enjoying life to the fullest, while still secretly coping with the disease. Subsequently she went public, and in July she had a mastectomy.

She offers me her best “Are you kidding?” look. “I put out with a song called No Secrets. I’m doing every interview, and they inquire, ‘What’s happening?’ and I respond, ‘Uh, nothing really’” she has just had to call off performances because she’s yet to undergo reconstructive surgery.

We meet at a photo studio in London. She is wearing a beige fake-leather jacket, denim trousers with ornate white designs, beige footwear and large glasses. Imagine biker chic meets 1970s Nana Mouskouri. “It seems like I’m in the 70s and I should have a man with facial hair.” Easy Rider, I say, referencing the film. “They used to call me that!” She smiles. Cornish is sharp-witted, unfiltered and filter-free. She says she has always wanted to try comedy and is aiming for her initial standup show next year. “I enjoy humor. During performances I often tease the fans.”

Medical Challenges and Discovery

The artist was planning an appearance at the awards show when she discovered a mass. “I quickly sought to get it checked, had an ultrasound, and they were, like, ‘It looks like nothing; your breasts are normal.’ And I responded, ‘But I can feel it. I have arm pain and numbness in my fingers whenever I get up.’ And they replied, ‘We should biopsy it?’ That was 28 March, the post-birthday.” It was a Friday. The specialist told her if it was bad news she’d call on the start of the week. By then she had persuaded herself it was fine. The way she describes it, it was inopportune to receive a diagnosis when she had a busy schedule.

“It was a fortnight prior from debuting the project after a long hiatus and no new music. And the doctor messaged and said, ‘Are you free at six?’ And I thought, ‘It’s virtual, probably routine.’ So I join the call expecting it’s all going to be positive, and she informs me, ‘Are you sitting down?.’ That sympathetic voice? And she reveals, ‘Unfortunately but your biopsy results have shown malignant cells.’” What was your reaction? “I said, ‘Well, that’s not great. What awful timing.’ The first thing I thought was, ‘I have to survive for my boy.’”

Some men find me challenging due to my self-awareness

She considered the operation terrifying and absurd. “I hate being put under. You’re escorted. In urgent cases you roll down in a bed, but this time I just walked with a gown on and my backside out. It felt surreal.” But, Cornish says, she’s been blessed. No chemo, no radiotherapy, just the procedure. “Cancer sucks, man, but you know what? I’m grateful it was caught soon. I had the mastectomy recently and my affected breast now appears as a grapefruit under a tight bedsheet.” Another grin. “The nipple was preserved.”

The subsequent surgery is both medical and cosmetic. Her chest, she remarks, are now “different sizes. They didn’t do an implant as small as my original. That’s impolite! I thought, no need to bully me, I’m already having a rough time. How offensive! It’s funny because I said I’d not undergo augmentation because I’ve got OCD, and I know they’d never be flawless. Illness changed that.”

Previous Struggles

She is no stranger to illness. She thinks her perspective on the cancer has been so positive because she’s used to physical challenges. Frequently they align with peak moments, acting as a reminder, or punch in the stomach, to remind her not to assume everything is fine. “Truly, I feel fate says, ‘You having a good time? Take a seat.’ From a young age, it has consistently accompanied achievements for me; a serious or unusual issue has affected my well-being.”

She recalls to her youth, already beginning starring in the West End in the production (she was cast at the age of nine). That’s when she was told about the heart condition Wolff-Parkinson-White syndrome, which can cause a fast heartbeat as well as dizziness and palpitations. “I attended rehearsals intermittently on an drip, and returning to the hospital at night.” She fast-forwards half a dozen years, and young Jessica has become part of the girl group the group while enrolled in the academy. “I secured a deal, and I had a stroke. Then when I was about to put out music in the year 2020 I had a car crash and my throat was injured and I was unable to vocalize for a twelve months.”

Wow, I say, slow down, I can’t keep up. A stroke so young? She nods|agrees
