‘It has pushed me to live more fully’: Jessie J on cancer, career returns and conquering the Chinese market

You couldn’t make it up, Jessie J says. There she was preparing for her first album release in nearly a decade, deeply enamored with her newish partner, and at long last the parent to a young child after dealing with conception issues for a decade, feeling invincible. Then in March she was diagnosed with a breast cancer diagnosis.

The musician, actual name J. Cornish, is renowned for being brutally honest. The LP, her latest release, was meant as an candid account, dealing with every bit of hardship she’d experienced since she last recorded music (a gynecological condition, losing a baby, broken romances, emotional abuse, suicide) with her usual frankness. The lead track, No Secrets, was released in April. But by then there existed a huge secret. The cancer. Later next release, her song Living My Best Life, came out in May and the artist was speaking publicly about how she was thriving, while at the same time living with the disease. Subsequently she disclosed her condition, and in July she underwent breast removal surgery.

She gives me her best “Are you kidding?” glance. “I release with a song called the track No Secrets. I’m giving every press talk, and they inquire, ‘So what’s new with you?’ and I’m, like, ‘Well, not much…’” Cornish has just had to postpone shows because she’s still waiting for reconstructive surgery.

Our interview takes place at a photo studio in London. She is wearing a tan faux-leather coat, jeans with ornate white designs, off-white boots and large glasses. Picture biker chic meets 70s singer aesthetic. “I feel like I’m in the 70s and I should have a man with facial hair.” Like the film, I say, referencing the film. “I was nicknamed that in school!” She grins. Cornish is sharp-witted, unfiltered and filter-free. She says she has always been interested in humor and is aiming for her standup debut soon. “I love making people laugh. When performing I basically roast the fans.”

Personal Battles and News

She was planning an performance at the Baftas when she found a lump. “I quickly sought to get it checked, had an ultrasound, and they were, like, ‘It looks like nothing; your breasts are normal.’ And I responded, ‘However, it’s there. I’ve got an achy arm and tingling in my hands whenever I get up.’ And they replied, ‘We should biopsy it?’ That was 28 March, the post-birthday.” It was a Friday. The doctor told her if it was concerning she’d call on the start of the week. By then the singer had assured herself it was nothing. The way she tells it, it was simply too inconvenient to get cancer when she had a busy schedule.

“Just two weeks before from launching this thing after eight years without an album and no new music. And she contacted me and said, ‘Can you talk at six?’ And I was, like, ‘It’s virtual, probably routine.’ So I join the call thinking it’s all going to be fine, and she says, ‘Are you sitting down?.’ You know that sad tone they use? And she reveals, ‘Unfortunately but your biopsy results have come back as aggressive cancer.’” What did you say? “I answered, ‘Oh, that’s not ideal, is it?. That’s not fucking great timing.’ Immediately I felt was, ‘I have to survive for my boy.’”

I’ve been labeled difficult for knowing myself

She considered the operation scary and bizarre. “I fear going under. They lead you. In urgent cases you go on a gurney, but this time I just marched with a gown on and my rear exposed. You feel like you’re in an episode of Black Mirror.” But, she adds, she’s been blessed. Without chemo or radio, just the procedure. “Cancer sucks, man, but you know what? Luckily it was detected early. I had the mastectomy a few months back and my affected breast now resembles a grapefruit under a tight bedsheet.” A further beam. “At least the nipple remains.”

The next operation is both medical and cosmetic. Her breasts, she observes, are now “different sizes. The size doesn’t match. How rude! I felt, don’t add insult to injury, I’m already having a difficult experience. How offensive! Ironically I said I’d never get my boobs done because I’ve got OCD, and I know they’d never be ideal. Cancer ruined that plan.”

A History of Health Challenges

The singer is accustomed to medical issues. She feels her perspective on the cancer has been so positive because she’s used to physical challenges. Many times they occur alongside career highs, serving as a tap on the shoulder, or blow, to remind her not to assume everything is fine. “Honestly, I feel life goes, ‘Things going well? Sit down.’ Since childhood, it has often paired with moments of success for me; a serious or unusual issue has happened to my health.”

She reminisces to her 11-year-old self, already beginning starring in the London theater in Whistle Down the Wind (she was selected at the age of nine). That’s when she was told about the cardiac issue WPW, which can cause a rapid pulse as well as lightheadedness and palpitations. “I rehearsed between visits on an IV drip, and returning to the hospital at night.” She skips forward half a dozen years, and young Jessica has become part of the female band the group while studying at the Brit School. “I signed my initial contract, and I had a stroke. Then when I was planning to release songs in recently I had a car crash and my voice box shifted and I couldn’t sing for a year.”

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