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

You can’t imagine it, Jessie J says. At that moment preparing for her first album release in eight years, blissfully happy with her current love, and at long last the parent to a young child after dealing with conception issues for a decade, feeling invincible. Suddenly in March she was diagnosed with a breast cancer diagnosis.

The musician, birth name J. Cornish, is renowned for telling it as it is. The LP, the provocatively titled album, was intended as an open book, tackling every moment of pain she’d experienced since she last worked on songs (endometriosis, pregnancy loss, failed relationships, psychological manipulation, mental health struggles) with her usual frankness. The lead track, No Secrets, was dropped in April. But by then there existed a huge secret. The illness. Then second single, Living My Best Life, came out in May and she was talking to press about how she was thriving, while still secretly living with her cancer. Subsequently she disclosed her condition, and in July she received surgical treatment.

She shoots me her best “Seriously?” expression. “I release with a song called No Secrets. I’m doing every interview, and they’re, like, ‘So what’s new with you?’ and I’m, like, ‘Erm, yeah, nothing …’” Cornish has just had to postpone shows because she’s yet to undergo follow-up surgery.

We’re at a photography studio in the capital. She is dressed in a light brown synthetic jacket, blue jeans with ornate white designs, cream boots and oversized specs. Picture biker chic meets 70s singer aesthetic. “As if I’m in the seventies and I should have a partner with a mustache.” Easy Rider, I say, referencing the movie. “They used to call me that!” She beams. She is sharp-witted, unfiltered and direct. She says she has always wanted to try comedy and is aiming for her initial standup show in the coming year. “I enjoy humor. On stage I basically roast the crowd.”

Medical Challenges and Discovery

She was planning an appearance at the ceremony when she discovered a mass. “I promptly visited to get it checked, had an ultrasound, and they said, ‘It looks like nothing; you’ve got really good dense breast tissue.’ And I insisted, ‘However, it’s there. My arm hurts and pins and needles in my hands whenever I get up.’ And they replied, ‘Well, let’s just do a biopsy?’ The date was March 28, the day after my birthday.” It was a Friday. The physician told her if it was bad news she’d reach out on the start of the week. By then the singer had assured herself it was okay. The way she explains it, it was simply too inconvenient to receive a diagnosis when she had so much on.

“It was a fortnight prior from launching this thing after a long hiatus and no new music. And she [the doctor] texted and said, ‘Is six okay?’ And I was, like, ‘It’s virtual, probably routine.’ So I join the call thinking it’s all going to be positive, and she goes, ‘Please take a seat.’ That sympathetic voice? And she says, ‘Unfortunately but your test results have come back as aggressive cancer.’” What did you say? “I said, ‘That’s unfortunate. The timing is terrible.’ My initial thought was, ‘I can’t die because my son needs me.’”

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

She considered the operation terrifying and absurd. “I fear going under. You’re escorted. During crises you go on a gurney, but now I just strolled down with a hospital gown and my rear exposed. Like a dystopian scene.” But, she notes, she’s been fortunate. No chemotherapy or radiation, just the procedure. “Cancer sucks, man, but yet Luckily it was detected early. I had the mastectomy recently and my right breast now resembles a grapefruit under a tight bedsheet.” A further beam. “I got to keep the nipple, though.”

The follow-up procedure is both medical and cosmetic. Her breasts, she notes, are now “uneven. They didn’t do an implant as small as my original. So inconsiderate! I felt, don’t add insult to injury, I’m already having a hard period. Such disrespect! Ironically I said I’d never get my boobs done because I’ve got obsessive tendencies, and I know they’d never be ideal. Illness changed that.”

Previous Struggles

She is familiar with health problems. She feels her attitude toward illness has been so positive because she’s familiar with medical emergencies. They have often coincided with professional successes, 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? Take a seat.’ Ever since I was a child, it has often paired with high points for me; something severe or obscure has affected my well-being.”

She recalls to her childhood, already making her debut featuring in the stage in Whistle Down the Wind (she was cast at the age of nine years old). That’s when she was found to have the medical problem a syndrome, which can cause a rapid pulse as well as dizziness and heart flutters. “I was going in and out of rehearsals on an IV drip, and going back into hospital at night.” She skips forward several years, and teenage Jess has joined the female band Soul Deep while enrolled in the performing arts school. “I signed my initial contract, and I had a stroke. Then when I was about to put out music in the year 2020 I had a collision and my throat was injured and I was unable to vocalize for a year.”

Wow, I say, wait, I am overwhelmed. At just 17? She nods|agrees
