‘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 comeback record in eight years, deeply enamored with her newish partner, and at long last the mom to a little one after struggling to conceive for a decade, riding high. Then in spring she was diagnosed with breast cancer.

The musician, birth name J. Cornish, is renowned for telling it as it is. The record, Don’t Tease Me With a Good Time, was intended as an transparent story, tackling every bit of hardship she’d endured since she last worked on songs (endometriosis, miscarriage, unsuccessful partnerships, gaslighting, suicide) with her usual frankness. The initial release, her single No Secrets, was released in April. But by then there existed a huge secret. Her diagnosis. Then next release, Living My Best Life, was released in May and Cornish was talking to press about how she was enjoying life to the fullest, while all the while coping with her cancer. Four weeks after she shared the news, and in early July she received surgical treatment.

She gives 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, ‘So what’s new with you?’ and I’m, like, ‘Well, not much…’” Cornish has just had to call off performances because she’s yet to undergo cosmetic procedures.

Our interview takes place at a studio in the capital. She is wearing a light brown synthetic jacket, jeans with detailed white appliqués, cream boots and big frames. Picture motorcycle style meets 1970s Nana Mouskouri. “It seems like I’m in the seventies and I should have a man with facial hair.” Easy Rider, I say, thinking of the movie. “I was nicknamed that in school!” She beams. Jessie is quick, unfiltered and filter-free. She says she has always fancied doing comedy and is aiming for her first comedy performance in the coming year. “I love making people laugh. When performing I basically roast the crowd.”

Medical Challenges and Discovery

The artist was preparing for an slot at the Baftas when she discovered a mass. “I promptly visited to get it examined, had an scan, and they told me, ‘It seems benign; your tissue is healthy.’ And I was, like, ‘But I can feel it. I have arm pain and pins and needles in my hands whenever I rise.’ And they said, ‘Well, let’s just do a biopsy?’ It happened on March 28, the day after my birthday.” It was a weekend eve. The specialist told her if it was bad news she’d reach out on the start of the week. By then she had assured herself it was nothing. The way she tells it, it was simply too inconvenient to receive a diagnosis when she had a busy schedule.

“It was a fortnight prior from releasing the album after years away and an extended break. And the doctor messaged and said, ‘Is six okay?’ And I thought, ‘Oh, it’s a Zoom, it won’t be anything.’ So I join the call thinking it’s all going to be fine, and she goes, ‘Are you sitting down?.’ You know that sad tone they use? And she says, ‘I’m so, so sorry but your biopsy results have come back as malignant cells.’” How did you respond? “I replied, ‘Well, that’s not great. What awful timing.’ The first thing I thought was, ‘I have to survive for my boy.’”

Some men find me challenging due to my self-awareness

She viewed the procedure scary and bizarre. “I fear going under. They walk you down. You know when you have emergency surgery you are wheeled, but this time I just strolled down with a medical attire and my backside out. You feel like you’re in an episode of Black Mirror.” But, she notes, she’s been lucky. No chemo, no radiotherapy, just the op. “Cancer sucks, man, but however I’m grateful it was caught soon. I had the mastectomy four months ago and my one side now appears as 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 boobs, she observes, are now “different sizes. They didn’t do an implant as small as my original. That’s impolite! I thought, no need to bully me, I’m already having a hard period. Such disrespect! Ironically I said I’d not undergo augmentation because I’ve got obsessive tendencies, and I know they’d never be ideal. My plans were disrupted.”

Previous Struggles

Cornish is familiar with health problems. She believes her attitude toward illness has been so optimistic because she’s used to physical challenges. They have often coincided with peak moments, functioning as a wake-up call, or punch in the stomach, to remind her not to be complacent. “Frankly, I feel the universe whispers, ‘Enjoying yourself? Sit down.’ From a young age, it has consistently accompanied high points for me; a serious or unusual issue has happened to my health.”

She reminisces to her youth, already starting her career starring in the stage in a musical (she was chosen at the age of 9). That’s when she was told about the heart condition Wolff-Parkinson-White syndrome, which can cause a tachycardia as well as vertigo and irregular beats. “I rehearsed between visits on an IV drip, and going back into hospital at night.” She skips forward several years, and 17-year-old Jess has become part of the female band the group while studying at the academy. “I signed my initial contract, and I had a stroke. Then when I was ready to debut in recently I had a car crash and my larynx moved up and I was unable to vocalize for a year.”

Hey, I say, wait, I need a moment. At just 17? She nods|agrees
