‘It has pushed me to live more fully’: Jessica Cornish on cancer, career returns and cracking China

You can’t imagine it, Jessie J states. At that moment gearing up for her comeback record in eight years, blissfully happy with her newish partner, and finally the mom to a little one after dealing with conception issues for ten years, feeling invincible. Suddenly in March she was diagnosed with a breast cancer diagnosis.

The musician, real name Jess Cornish, is famous for telling it as it is. The album, her latest release, was intended as an open book, addressing every ounce of devastation she’d faced since she last recorded music (endometrial issues, miscarriage, failed relationships, emotional abuse, mental health struggles) with characteristic openness. The initial release, the song No Secrets, was released in April. But by then there was a mighty secret. The illness. Then next release, her song Living My Best Life, debuted in late spring and Cornish was talking to press about how she was thriving, while all the while living with her cancer. Subsequently she shared the news, and in the start of summer she had a mastectomy.

She offers me her best “What the fuck?” glance. “I put out with a song called No Secrets. I’m doing every interview, and they’re, like, ‘What’s happening?’ and I’m, like, ‘Well, not much…’” the singer has just had to cancel tour dates because she’s awaiting reconstructive surgery.

We’re at a photo studio in London. She is dressed in a tan faux-leather coat, denim trousers with elaborate white patches, off-white boots and large glasses. Imagine biker chic meets 70s singer aesthetic. “As if I’m in the seventies and I should have a boyfriend with a big tache.” A biker reference, I say, thinking of the film. “They used to call me that!” She grins. Jessie is quick, unfiltered and direct. She says she has always fancied doing comedy and is aiming for her initial standup show in the coming year. “I love making people laugh. On stage I often tease the audience.”

Health Struggles and Diagnosis

Cornish was preparing for an appearance at the Baftas when she noticed an abnormality. “I quickly sought to get it checked, had an test, and they told me, ‘It looks like nothing; your breasts are normal.’ And I insisted, ‘Yet I sense it. I’ve got an achy arm and tingling in my hands whenever I get up.’ And they said, ‘Well, let’s just do a biopsy?’ It happened on March 28, the day after my birthday.” It was a weekend eve. The specialist told her if it was concerning she’d call on the Monday. By then Cornish had convinced herself it was okay. The way she describes it, it was inopportune to get cancer when she had a busy schedule.

“It was a fortnight prior from releasing the album after a long hiatus and no new music. And the doctor messaged and said, ‘Can you talk at six?’ And I was, like, ‘It’s virtual, probably routine.’ So I join the call believing it’s all going to be fine, and she says, ‘Are you sitting down?.’ The solemn tone? And she says, ‘I’m so, so sorry but your reports have indicated aggressive cancer.’” How did you respond? “I answered, ‘Well, that’s not great. That’s not fucking great timing.’ Immediately I felt was, ‘I can’t die because my son needs me.’”

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

She considered the operation frightening and surreal. “I fear going under. You’re escorted. During crises you go on a gurney, but this time I just strolled down with a medical attire and my rear exposed. You feel like you’re in an episode of Black Mirror.” But, she adds, she’s been blessed. No chemo, no radiotherapy, just the procedure. “It’s terrible, but you know what? Luckily it was detected early. I underwent removal a few months back and my affected breast now looks like a grapefruit under a tight bedsheet.” A further beam. “The nipple was preserved.”

The subsequent surgery is therapeutic and aesthetic. Her breasts, she remarks, are now “uneven. The size doesn’t match. That’s impolite! I felt, no need to bully me, I’m already having a rough time. How offensive! Amusingly I said I’d avoid breast surgery because I’ve got obsessive tendencies, and I know they’d never be ideal. Cancer ruined that plan.”

A History of Health Challenges

She is accustomed to medical issues. She thinks her perspective on the cancer has been so upbeat because she’s experienced in health crises. They have often coincided with peak moments, functioning as a wake-up call, or shock, to highlight not to assume everything is fine. “Frankly, I feel life goes, ‘Things going well? Hold on.’ From a young age, it has often paired with high points for me; a serious or unusual issue has happened to my health.”

She takes me back to her childhood, already making her debut starring in the London theater in Whistle Down the Wind (she was chosen at the age of 9). That’s when she was diagnosed with the medical problem WPW, which can cause a tachycardia as well as vertigo and irregular beats. “I attended rehearsals intermittently on an IV drip, and going back into hospital at night.” She fast-forwards six years, and young Jessica has entered the trio Soul Deep while enrolled in the academy. “I just got my first record deal, and I had a brain incident. Then when I was about to put out music in 2020 I had a collision and my throat was injured and I lost my voice for a twelve months.”

Wow, I say, slow down, I need a moment. At just 17? She nods|agrees
