‘It has taught me to embrace life more’: Jessica Cornish on cancer, comebacks and conquering the Chinese market

You couldn’t make it up, Jessie J remarks. There she was preparing for her first album release in nearly a decade, blissfully happy with her newish partner, and at long last the parent to a young child after struggling to conceive for a decade, feeling invincible. Suddenly in spring she was told she had a breast cancer diagnosis.

The artist, real name J. Cornish, is known for telling it as it is. The LP, her latest release, was meant as an transparent story, dealing with every moment of pain she’d experienced since she last recorded music (endometriosis, losing a baby, broken romances, emotional abuse, suicidal thoughts) with characteristic openness. The initial release, No Secrets, was launched in April. But by then there was a mighty secret. The illness. Later second single, the upbeat Living My Best Life, came out in late spring and Cornish was giving interviews about how she was enjoying life to the fullest, while still secretly coping with breast cancer. Subsequently she shared the news, and in the start of summer she had a mastectomy.

She shoots me her best “What the fuck?” look. “I put out with a song called No Secrets. I’m conducting every media appearance, and they’re, like, ‘What’s happening?’ and I respond, ‘Well, not much…’” Cornish has just had to call off performances because she’s awaiting cosmetic procedures.

We meet at a photo studio in London. She is sporting a tan faux-leather coat, jeans with detailed white appliqués, cream boots and oversized specs. Picture biker chic meets vintage look. “I feel like I’m in the seventies and I should have a man with facial hair.” Like the film, I say, referencing the picture. “That’s what people called me at school!” She beams. She is quick, bold and direct. She says she has always been interested in humor and is aiming for her initial standup show next year. “I love making people laugh. When performing I frequently joke about the fans.”

Health Struggles and Diagnosis

She was planning an slot at the awards show when she discovered a mass. “I quickly sought to get it checked, had an test, and they were, like, ‘It seems benign; you’ve got really good dense breast tissue.’ And I responded, ‘Yet I sense it. I have arm pain and tingling in my hands whenever I get up.’ And they suggested, ‘We should biopsy it?’ The date was March 28, the post-birthday.” It was a weekend eve. The specialist told her if it was serious she’d contact on the start of the week. By then Cornish had convinced herself it was okay. The way she tells it, it was inopportune to get cancer when she had a busy schedule.

“We’re two weeks away from launching this thing after eight years without an album and four years without a single. And the doctor messaged and said, ‘Can you talk at six?’ And I assumed, ‘It’s virtual, probably routine.’ So I jump on the Zoom expecting it’s all going to be fine, and she informs me, ‘Are you sitting down?.’ The solemn tone? And she says, ‘I regret to inform you but your reports have come back as malignant cells.’” What was your reaction? “I replied, ‘That’s unfortunate. The timing is terrible.’ The first thing I thought was, ‘I can’t die because my son needs me.’”

Some men find me challenging due to my self-awareness

She considered the operation terrifying and absurd. “I dislike anesthesia. They walk you down. In urgent cases you go on a gurney, but now I just strolled down with a medical attire and my backside out. It felt surreal.” But, Cornish says, she’s been lucky. No chemotherapy or radiation, just the op. “Cancer sucks, man, but however Luckily it was detected early. The surgery happened four months ago and my one side now looks like a odd shape.” Another grin. “I got to keep the nipple, though.”

The subsequent surgery is for health and appearance. Her boobs, she observes, are now “different sizes. The size doesn’t match. So inconsiderate! I felt, no need to bully me, I’m already having a rough time. So rude! Amusingly I said I’d avoid breast surgery because I’ve got OCD, and I know they’d never be perfect. Cancer ruined that plan.”

A History of Health Challenges

Cornish is no stranger to illness. She feels her perspective on the cancer has been so upbeat because she’s used to medical emergencies. Frequently they align with professional successes, serving as a tap on the shoulder, or shock, to highlight not to assume everything is fine. “Honestly, I feel the universe whispers, ‘You having a good time? Sit down.’ Since childhood, it has always gone alongside moments of success for me; a major or strange event has happened to my health.”

She reminisces to her childhood, already starting her career performing in the West End in the production (she was cast at the age of nine years old). That’s when she was told about the cardiac issue WPW, which can cause a rapid pulse as well as vertigo and irregular beats. “I rehearsed between visits on an intravenous line, and being readmitted at night.” She jumps ahead six years, and teenage Jess has become part of the girl group Soul Deep while attending the performing arts school. “I just got my first record deal, and I had a brain incident. Then when I was about to put out music in the year 2020 I had a collision and my larynx moved up and I couldn’t sing for a twelve months.”

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