‘It has pushed me to live more fully’: Jessica Cornish on her health battle, career returns and conquering the Chinese market

You wouldn’t believe it, Jessie J says. At that moment readying for her first album release in eight years, deeply enamored with her recent boyfriend, and finally the mom to a little one after dealing with conception issues for ten years, feeling invincible. Suddenly in March she was diagnosed with a breast cancer diagnosis.

The musician, real name J. Cornish, is renowned for being brutally honest. The record, the provocatively titled album, was meant as an open book, addressing every ounce of devastation she’d endured since she last recorded music (endometriosis, pregnancy loss, failed relationships, psychological manipulation, mental health struggles) with characteristic openness. The initial release, her single No Secrets, was released in April. But by then there was a mighty secret. The cancer. Then follow-up track, the upbeat Living My Best Life, debuted in May and Cornish was speaking publicly about how she was enjoying life to the fullest, while all the while coping with the disease. Four weeks after she disclosed her condition, and in the start of summer she underwent breast removal surgery.

She gives me her best “Are you kidding?” glance. “I release with a song called No Secrets. I’m doing every press talk, and they’re, like, ‘What’s happening?’ and I’m, like, ‘Uh, nothing really’” Cornish has just had to cancel tour dates because she’s yet to undergo reconstructive surgery.

Our interview takes place at a studio in London. She is wearing a tan faux-leather coat, jeans with ornate white designs, cream boots and big frames. Think motorcycle style meets 1970s Nana Mouskouri. “As if I’m in the seventies and I should have a partner with a mustache.” Easy Rider, I say, thinking of the picture. “They used to call me that!” She beams. Jessie is fast-thinking, bold and blunt. She says she has always been interested in humor and is hoping to make her first comedy performance next year. “I love making people laugh. On stage I frequently joke about the crowd.”

Medical Challenges and Discovery

The artist was planning an appearance at the Baftas when she discovered a mass. “I promptly visited to get it checked, had an scan, and they said, ‘It seems benign; your tissue is healthy.’ And I was, like, ‘Yet I sense it. I have arm pain and tingling in my hands whenever I wake up.’ And they suggested, ‘Well, let’s just do a biopsy?’ That was 28 March, the following my birthday.” It was a Friday. The specialist told her if it was concerning she’d call on the start of the week. By then she had convinced herself it was okay. The way she tells it, it was inopportune to face illness when she had so much on.

“It was a fortnight prior from releasing the album after eight years without an album and an extended break. And she [the doctor] texted and said, ‘Are you free at six?’ And I was, like, ‘It’s virtual, probably routine.’ So I jump on the Zoom thinking it’s all going to be fine, and she says, ‘Are you sitting down?.’ That sympathetic voice? And she says, ‘I regret to inform you but your biopsy results have shown 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.’”

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

She viewed the procedure frightening and surreal. “I hate being put under. You’re escorted. During crises you go on a gurney, but this time I just marched with a hospital gown and my backside out. It felt surreal.” But, she notes, she’s been blessed. No chemo, no radiotherapy, just the procedure. “Cancer is awful, but however Thank fuck I found it early. I had the mastectomy a few months back and my right breast now appears as a fruit under fabric.” She smiles again. “At least the nipple remains.”

The follow-up procedure is both medical and cosmetic. Her chest, she remarks, are now “uneven. They didn’t do an implant as small as my original. That’s impolite! I reflected, no need to bully me, I’m already having a difficult experience. Such disrespect! Amusingly I said I’d not undergo augmentation because I’ve got OCD, and I know they’d never be ideal. Illness changed that.”

Past Medical Issues

The singer is no stranger to illness. She thinks her perspective on the cancer has been so optimistic because she’s experienced in physical challenges. They have often coincided with peak moments, acting as a reminder, or shock, to highlight not to take anything for granted. “Truly, I feel life goes, ‘You having a good time? Take a seat.’ Since childhood, it has often paired with achievements for me; a serious or unusual issue has happened to my health.”

She takes me back to her youth, already beginning performing in the stage in the production (she was cast at the age of nine years old). That’s when she was told about the heart condition a syndrome, which can cause a rapid pulse as well as lightheadedness and heart flutters. “I attended rehearsals intermittently on an drip, and returning to the hospital at night.” She jumps ahead six years, and teenage Jess has joined the trio the group while studying at the academy. “I signed my initial contract, and I had a stroke. Then when I was about to put out music in recently I had a automobile accident and my voice box shifted and I lost my voice for a year.”

Wow, I say, hold on, I need a moment. You really had a stroke at 17? She nods|agrees
