‘It has made me live life more’: Jessica Cornish on cancer, comebacks and conquering the Chinese market

You couldn’t make it up, Jessie J remarks. There she was gearing up for her first album release in nearly a decade, blissfully happy with her current love, and finally the mom to a little one after facing fertility challenges for ten years, feeling invincible. Suddenly in spring she was told she had breast cancer.

The artist, real name J. Cornish, is renowned for being brutally honest. The LP, Don’t Tease Me With a Good Time, was meant as an candid account, addressing every bit of hardship she’d experienced since she last made an album (endometrial issues, miscarriage, unsuccessful partnerships, psychological manipulation, suicide) with characteristic openness. The first single, No Secrets, was released in the spring. But by then there existed a huge secret. The cancer. Later second single, Living My Best Life, came out in May and she was talking to press about how she was thriving, while still secretly coping with breast cancer. A month later she went public, and in the start of summer she underwent breast removal surgery.

She offers me her best “Are you kidding?” expression. “I put out with a song called No Secrets. I’m conducting every interview, and they ask, ‘What’s happening?’ and I respond, ‘Uh, nothing really’” Cornish has just had to postpone shows because she’s still waiting for cosmetic procedures.

Our interview takes place at a photography studio in London. She is dressed in a tan faux-leather coat, jeans with detailed white appliqués, cream boots and large glasses. Picture motorcycle style meets vintage look. “I feel like I’m in the 70s and I should have a boyfriend with a big tache.” Like the film, I say, recalling the movie. “That’s what people called me at school!” She grins. Jessie is fast-thinking, unfiltered and filter-free. She says she has always wanted to try comedy and is hoping to make her standup debut next year. “I enjoy humor. During performances I basically roast the crowd.”

Medical Challenges and Discovery

Cornish was preparing for an appearance at the Baftas when she noticed an abnormality. “I quickly sought to get it examined, had an ultrasound, and they were, like, ‘It appears fine; your breasts are normal.’ And I responded, ‘Yet I sense it. My arm hurts and numbness in my fingers whenever I wake up.’ And they replied, ‘How about 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 contact on the start of the week. By then Cornish had assured herself it was nothing. The way she explains it, it was simply too inconvenient to receive a diagnosis when she had so much on.

“We’re two weeks away from launching this thing after years away and no new music. And she contacted me and said, ‘Are you free at six?’ And I assumed, ‘It’s virtual, probably routine.’ So I log in believing it’s all going to be positive, and she informs me, ‘Are you sitting down?.’ You know that sad tone they use? And she continues, ‘Unfortunately but your test results have indicated high-grade cancer cells.’” What was your reaction? “I replied, ‘Well, that’s not great. What awful timing.’ My initial thought was, ‘My child depends on 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 hate being put under. They walk you down. In urgent cases you are wheeled, but then I just marched with a hospital gown and my bum hanging out. It felt surreal.” But, she notes, she’s been blessed. Without chemo or radio, just the op. “It’s terrible, but yet Luckily it was detected early. The surgery happened a few months back and my affected breast now resembles a fruit under fabric.” She smiles again. “I got to keep the nipple, though.”

The next operation is therapeutic and aesthetic. Her chest, she remarks, are now “different sizes. The size doesn’t match. So inconsiderate! I felt, don’t add insult to injury, I’m already having a difficult experience. So rude! Amusingly I said I’d never get my boobs done because I’ve got OCD, and I know they’d never be flawless. Cancer ruined that plan.”

A History of Health Challenges

Cornish is familiar with health problems. She feels her outlook on her diagnosis has been so positive because she’s familiar with physical challenges. Frequently they align with peak moments, serving as a tap on the shoulder, or shock, to make her recall not to assume everything is fine. “Honestly, I feel life goes, ‘Enjoying yourself? Hold on.’ From a young age, it has always gone alongside high points for me; something severe or obscure has affected my well-being.”

She recalls to her childhood, already beginning featuring in the West End in a musical (she was cast at the age of nine years old). That’s when she was diagnosed with the medical problem a syndrome, which can cause a fast heartbeat as well as lightheadedness and irregular beats. “I attended rehearsals intermittently on an IV drip, and returning to the hospital at night.” She skips forward six years, and teenage Jess has joined the trio Soul Deep while attending the academy. “I secured a deal, and I had a brain incident. Then when I was about to put out music in the year 2020 I had a automobile accident and my throat was injured and I was unable to vocalize for a long period.”

Wow, I say, slow down, I can’t keep up. At just 17? She nods|agrees
