‘It has taught me to embrace life more’: Jessica Cornish on her health battle, career returns and conquering the Chinese market

You couldn’t make it up, Jessie J says. At that moment gearing up for her comeback record in eight years, blissfully happy with her current love, and finally the mom to a little one after facing fertility challenges for a decade, on top of the world. Suddenly in March she was found to have a breast cancer diagnosis.

The singer-songwriter, birth name Jessica Cornish, is famous for telling it as it is. The LP, her latest release, was intended as an transparent story, tackling every bit of hardship she’d endured since she last worked on songs (a gynecological condition, losing a baby, broken romances, psychological manipulation, suicidal thoughts) with her usual frankness. The first single, No Secrets, was released in the spring. But by then there existed a huge secret. The cancer. Later next release, Living My Best Life, came out in late spring and she was giving interviews about how she was enjoying life to the fullest, while all the while dealing with the disease. A month later she shared the news, and in early July she had a mastectomy.

She shoots me her best “Are you kidding?” expression. “I come out with a song called the track No Secrets. I’m doing every media appearance, and they ask, ‘Any updates?’ and I respond, ‘Well, not much…’” she has just had to call off performances because she’s yet to undergo reconstructive surgery.

We’re at a photo studio in London. She is sporting a tan faux-leather coat, blue jeans with elaborate white patches, beige footwear and big frames. Think biker chic meets vintage look. “I feel like I’m in the seventies and I should have a boyfriend with a big tache.” A biker reference, I say, referencing the picture. “That’s what people called me at school!” She beams. She is fast-thinking, bold and blunt. She says she has always wanted to try comedy and is planning to attempt her standup debut soon. “I enjoy humor. On stage I frequently joke about the audience.”

Medical Challenges and Discovery

Cornish was planning an slot at the awards show when she discovered a mass. “I quickly sought to get it examined, had an ultrasound, and they said, ‘It looks like nothing; your breasts are normal.’ And I responded, ‘But I can feel it. I have arm pain and tingling in my hands whenever I rise.’ And they said, ‘We should biopsy it?’ The date was March 28, the post-birthday.” It was a weekend eve. The physician told her if it was serious she’d call on the Monday. By then she had assured herself it was fine. The way she describes it, it was just bad timing to face illness when she had a busy schedule.

“We’re two weeks away from launching this thing after a long hiatus and an extended break. And the doctor messaged and said, ‘Can you talk at six?’ And I assumed, ‘Oh, it’s a Zoom, it won’t be anything.’ So I join the call thinking it’s all going to be good, and she informs me, ‘You might want to sit.’ That sympathetic voice? And she says, ‘Unfortunately but your reports have come back as aggressive cancer.’” What did you say? “I replied, ‘That’s unfortunate. That’s not fucking great timing.’ Immediately I felt was, ‘I have to survive for my boy.’”

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

She found the surgery terrifying and absurd. “I hate being put under. They lead you. During crises you roll down in a bed, but now I just walked with a hospital gown and my backside out. Like a dystopian scene.” But, Cornish says, she’s been lucky. No chemotherapy or radiation, just the surgery. “It’s terrible, but yet Luckily it was detected early. The surgery happened recently and my one side now appears as a fruit under fabric.” A further beam. “The nipple was preserved.”

The next operation is therapeutic and aesthetic. Her chest, she remarks, are now “uneven. The size doesn’t match. How rude! I reflected, no need to bully me, I’m already having a rough time. How offensive! Ironically I said I’d never get my boobs done because I’ve got OCD, and I know they’d never be flawless. 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 experienced in physical challenges. They have often coincided with professional successes, functioning as a wake-up call, or shock, to highlight not to assume everything is fine. “Truly, I feel life goes, ‘Things going well? Take a seat.’ From a young age, it has often paired with moments of success for me; a serious or unusual issue has impacted my body.”

She takes me back to her 11-year-old self, already starting her career starring in the stage in a musical (she was selected at the age of nine). That’s when she was found to have the cardiac issue a syndrome, which can cause a fast heartbeat as well as lightheadedness and irregular beats. “I attended rehearsals intermittently on an IV drip, and being readmitted at night.” She jumps ahead half a dozen years, and teenage Jess has entered the girl group Soul Deep while enrolled in the Brit School. “I secured a deal, and I had a stroke. Then when I was planning to release songs in 2020 I had a collision and my throat was injured and I lost my voice for a year.”

Oi, I say, slow down, I am overwhelmed. You really had a stroke at 17? She nods|agrees
