‘It has made me live life more’: Jessica Cornish on her health battle, comebacks and cracking China

You wouldn’t believe it, Jessie J says. At that moment gearing up for her first album release in nearly a decade, deeply enamored with her current love, and at long last the mom to a little one after facing fertility challenges for a decade, on top of the world. Then in March she was diagnosed with cancer in her breast.

The singer-songwriter, real name J. Cornish, is renowned for telling it as it is. The album, the provocatively titled album, was meant as an open book, tackling every bit of hardship she’d faced since she last recorded music (endometriosis, losing a baby, broken romances, psychological manipulation, suicide) with typical candour. The first single, the song No Secrets, was launched in the spring. But by then there remained a major undisclosed truth. The illness. Then follow-up track, Living My Best Life, debuted in May and the artist was talking to press about how she was enjoying life to the fullest, while all the while living with her cancer. Subsequently she disclosed her condition, and in July she received surgical treatment.

She gives me her best “What the fuck?” look. “I come out with a song called No Secrets. I’m doing every press talk, and they ask, ‘So what’s new with you?’ and I answer, ‘Well, not much…’” Cornish has just had to cancel tour dates because she’s awaiting reconstructive surgery.

We’re at a photo studio in the capital. She is dressed in a beige fake-leather jacket, blue jeans with ornate white designs, beige footwear and oversized specs. Picture rocker vibe meets vintage look. “It seems like I’m in the seventies and I should have a boyfriend with a big tache.” A biker reference, I say, referencing the movie. “That’s what people called me at school!” She grins. Jessie is fast-thinking, bold and filter-free. She says she has always wanted to try comedy and is hoping to make her initial standup show next year. “I love making people laugh. When performing I often tease the fans.”

Health Struggles and Diagnosis

Cornish was planning an slot at the Baftas when she found a lump. “I promptly visited to get it checked, had an scan, and they said, ‘It appears fine; you’ve got really good dense breast tissue.’ And I was, like, ‘However, it’s there. I have arm pain and tingling in my hands whenever I get up.’ And they said, ‘We should biopsy it?’ That was 28 March, the post-birthday.” It was a weekend eve. The specialist told her if it was serious she’d contact on the Monday. By then she had assured herself it was fine. The way she describes it, it was just bad timing to face illness when she had so much on.

“It was a fortnight prior from releasing the album after eight years without an album and no new music. And she contacted me and said, ‘Is six okay?’ And I thought, ‘Oh, it’s a Zoom, it won’t be anything.’ So I log in expecting it’s all going to be good, and she informs me, ‘Please take a seat.’ You know that sad tone they use? And she says, ‘I regret to inform you but your reports have indicated malignant cells.’” What was your reaction? “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 considered the operation scary and bizarre. “I fear going under. They walk you down. In urgent cases you are wheeled, but then I just marched with a medical attire and my bum hanging out. It felt surreal.” But, she adds, she’s been fortunate. No chemotherapy or radiation, just the procedure. “It’s terrible, but you know what? Thank fuck I found it early. I underwent removal four months ago and my right breast now appears as a fruit under fabric.” A further beam. “At least the nipple remains.”

The follow-up procedure is therapeutic and aesthetic. Her chest, she remarks, are now “different sizes. The implant is larger than before. That’s impolite! I thought, why make it worse, I’m already having a rough time. How offensive! Ironically I said I’d never get my boobs done because I’ve got perfectionism, and I know they’d never be perfect. My plans were disrupted.”

Past Medical Issues

The singer is no stranger to illness. She feels her attitude toward illness has been so positive because she’s used to health crises. Many times they occur alongside peak moments, acting as a reminder, or blow, to remind her not to be complacent. “Frankly, I feel fate says, ‘Things going well? Sit down.’ Ever since I was a child, it has always gone alongside achievements for me; something severe or obscure has affected my well-being.”

She takes me back to her 11-year-old self, already starting her career performing in the stage in a musical (she was selected at the age of 9). That’s when she was told about the medical problem a syndrome, which can cause a fast heartbeat as well as vertigo and palpitations. “I rehearsed between visits on an drip, and returning to the hospital at night.” She skips forward six years, and 17-year-old Jess has become part of the trio the group while attending the Brit School. “I signed my initial contract, and I had a cerebral event. Then when I was ready to debut in the year 2020 I had a car crash and my larynx moved up and I lost my voice for a long period.”

Oi, I say, wait, I am overwhelmed. At just 17? She nods|agrees
