‘It has pushed me to live more fully’: Jessica Cornish on cancer, comebacks and conquering the Chinese market

You wouldn’t believe it, Jessie J remarks. At that moment gearing up for her first album release in nearly a decade, blissfully happy with her current love, and finally the parent to a young child after dealing with conception issues for ten years, riding high. Suddenly in spring she was told she had cancer in her breast.

The artist, actual name J. Cornish, is famous 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 (endometriosis, losing a baby, broken romances, gaslighting, mental health struggles) with typical candour. The initial release, her single No Secrets, was launched in the spring. But by then there was a mighty secret. Her diagnosis. Later follow-up track, her song Living My Best Life, debuted in May and Cornish was talking to press about how she was enjoying life to the fullest, while still secretly dealing with breast cancer. Subsequently she shared the news, and in July she received surgical treatment.

She offers me her best “What the fuck?” glance. “I put out with a song called No Secrets. I’m giving every interview, and they ask, ‘Any updates?’ and I’m, like, ‘Uh, nothing really’” Cornish has just had to postpone shows because she’s still waiting for reconstructive surgery.

We meet at a photo studio in London. She is sporting a beige fake-leather jacket, blue jeans with detailed white appliqués, cream boots and large glasses. Think biker chic meets 1970s Nana Mouskouri. “It seems like I’m in the 70s and I should have a boyfriend with a big tache.” Easy Rider, I say, recalling the movie. “They used to call me that!” She beams. Cornish is fast-thinking, irreverent and blunt. She says she has always been interested in humor and is hoping to make her standup debut soon. “I like entertaining. On stage I basically roast the crowd.”

Health Struggles and Diagnosis

She was planning an performance at the awards show when she found a lump. “I immediately went to get it examined, had an scan, and they were, like, ‘It seems benign; your breasts are normal.’ And I insisted, ‘However, it’s there. I have arm pain and pins and needles in my hands whenever I wake up.’ And they said, ‘We should biopsy it?’ That was 28 March, the following my birthday.” It was a weekend eve. The doctor told her if it was concerning she’d reach out on the start of the week. By then Cornish had convinced herself it was okay. The way she tells it, it was simply too inconvenient to face illness when she had many commitments.

“We’re two weeks away from launching this thing after years away and four years without a single. And she [the doctor] texted and said, ‘Can you talk at six?’ And I was, like, ‘Oh, it’s a Zoom, it won’t be anything.’ So I log in believing it’s all going to be fine, and she goes, ‘Are you sitting down?.’ The solemn tone? And she reveals, ‘I’m so, so sorry but your test results have shown malignant cells.’” What was your reaction? “I replied, ‘Oh, that’s not ideal, is it?. The timing is terrible.’ Immediately I felt was, ‘My child depends on me.’”

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

She viewed the procedure scary and bizarre. “I hate being put under. They walk you down. In urgent cases you are wheeled, but then I just marched with a gown on and my bum hanging out. Like a dystopian scene.” But, she notes, she’s been fortunate. No chemo, no radiotherapy, just the op. “Cancer is awful, but yet Thank fuck I found it early. I underwent removal a few months back and my affected breast now appears as a grapefruit under a tight bedsheet.” Another grin. “The nipple was preserved.”

The follow-up procedure is for health and appearance. Her chest, she observes, are now “different sizes. The implant is larger than before. That’s impolite! I thought, don’t add insult to injury, I’m already having a rough time. Such disrespect! Amusingly I said I’d not undergo augmentation because I’ve got perfectionism, and I know they’d never be flawless. My plans were disrupted.”

Past Medical Issues

She is familiar with health problems. She thinks her outlook on her diagnosis has been so optimistic because she’s experienced in physical challenges. Frequently they align with peak moments, serving as a tap on the shoulder, or blow, to highlight not to assume everything is fine. “Frankly, I feel the universe whispers, ‘Enjoying yourself? Take a seat.’ Ever since I was a child, it has often paired with high points for me; a serious or unusual issue has affected my well-being.”

She reminisces to her 11-year-old self, already making her debut starring in the London theater in the production (she was chosen at the age of nine years old). That’s when she was diagnosed with the medical problem a syndrome, which can cause a rapid pulse as well as vertigo and heart flutters. “I was going in and out of rehearsals on an drip, and returning to the hospital at night.” She jumps ahead six years, and teenage Jess has joined the girl group Soul Deep while attending the performing arts school. “I secured a deal, and I had a cerebral event. Then when I was about to put out music in 2020 I had a car crash and my voice box shifted and I couldn’t sing for a twelve months.”

Wow, I say, slow down, I am overwhelmed. A stroke so young? She nods|agrees
