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

You wouldn’t believe it, Jessie J says. There she was readying for her comeback record in eight years, blissfully happy with her recent boyfriend, and at long last the mother of a toddler after struggling to conceive for a decade, riding high. Then in spring she was diagnosed with breast cancer.

The musician, real name Jess Cornish, is renowned for telling it as it is. The record, the provocatively titled album, was meant as an candid account, tackling every ounce of devastation she’d experienced since she last recorded music (a gynecological condition, pregnancy loss, failed relationships, emotional abuse, suicidal thoughts) with typical candour. The lead track, No Secrets, was launched in April. But by then there existed a huge secret. Her diagnosis. Then second single, the upbeat Living My Best Life, was released in late spring and the artist was speaking publicly about how she was living her best life, while still secretly coping with the disease. Subsequently she went public, and in July she underwent breast removal surgery.

She offers me her best “Seriously?” expression. “I release with a song called No Secrets. I’m giving every media appearance, and they ask, ‘So what’s new with you?’ and I answer, ‘Erm, yeah, nothing …’” the singer has just had to call off performances because she’s yet to undergo follow-up surgery.

We meet at a photography studio in the capital. She is sporting a light brown synthetic jacket, jeans with ornate white designs, off-white boots and oversized specs. Imagine rocker vibe meets vintage look. “As if I’m in the 70s and I should have a man with facial hair.” Easy Rider, I say, recalling the picture. “I was nicknamed that in school!” She grins. She is fast-thinking, unfiltered and blunt. She says she has always been interested in humor and is aiming for her standup debut next year. “I enjoy humor. During performances I frequently joke about the audience.”

Health Struggles and Diagnosis

She was preparing for an appearance at the Baftas when she noticed an abnormality. “I promptly visited to get it examined, had an scan, and they told me, ‘It looks like nothing; your tissue is healthy.’ And I insisted, ‘But I can feel it. I have arm pain and tingling in my hands whenever I get up.’ And they replied, ‘We should biopsy it?’ That was 28 March, 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 she had assured herself it was okay. The way she describes it, it was inopportune to receive a diagnosis when she had many commitments.

“It was a fortnight prior from debuting the project after a long hiatus and no new music. And she contacted me and said, ‘Can you talk at six?’ And I thought, ‘Oh, it’s a Zoom, it won’t be anything.’ So I jump on the Zoom believing it’s all going to be good, and she goes, ‘Are you sitting down?.’ The solemn tone? And she reveals, ‘Unfortunately but your test results have come back as aggressive cancer.’” What was your reaction? “I answered, ‘Well, that’s not great. That’s not fucking great timing.’ Immediately I felt was, ‘I have to survive for my boy.’”

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

She found the surgery frightening and surreal. “I dislike anesthesia. You’re escorted. In urgent cases you go on a gurney, but this time I just marched with a gown on and my bum hanging out. Like a dystopian scene.” But, she notes, she’s been lucky. No chemo, no radiotherapy, just the surgery. “Cancer is awful, but yet Thank fuck I found it early. The surgery happened a few months back and my one side now appears as a odd shape.” A further beam. “I got to keep the nipple, though.”

The next operation is therapeutic and aesthetic. Her breasts, she observes, are now “asymmetrical. The size doesn’t match. So inconsiderate! I felt, don’t add insult to injury, I’m already having a difficult experience. Such disrespect! It’s funny because I said I’d avoid breast surgery because I’ve got obsessive tendencies, and I know they’d never be perfect. Illness changed that.”

Past Medical Issues

Cornish is no stranger to illness. She thinks her attitude toward illness has been so positive because she’s used to physical challenges. They have often coincided with peak moments, acting as a reminder, or punch in the stomach, to remind her not to be complacent. “Truly, I feel life goes, ‘You having a good time? Hold on.’ Ever since I was a child, it has always gone alongside moments of success for me; a serious or unusual issue has happened to my health.”

She reminisces to her childhood, already starting her career starring in the London theater in Whistle Down the Wind (she was selected at the age of nine). That’s when she was diagnosed with the heart condition a syndrome, which can cause a tachycardia as well as lightheadedness and heart flutters. “I attended rehearsals intermittently on an intravenous line, and returning to the hospital at night.” She skips forward six years, and 17-year-old Jess has joined the female band Soul Deep while attending the Brit School. “I secured a deal, and I had a brain incident. Then when I was planning to release songs in the year 2020 I had a car crash and my voice box shifted and I couldn’t sing for a long period.”

Hey, I say, slow down, I can’t keep up. You really had a stroke at 17? She nods|agrees
