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

You wouldn’t believe it, Jessie J states. At that moment readying for her comeback record in eight years, deeply enamored with her recent boyfriend, and at long last the mother of a toddler after struggling to conceive for ten years, feeling invincible. Suddenly in March she was diagnosed with a breast cancer diagnosis.

The artist, birth name Jess Cornish, is known for being brutally honest. The record, the provocatively titled album, was intended as an open book, addressing every bit of hardship she’d endured since she last recorded music (a gynecological condition, miscarriage, broken romances, emotional abuse, suicidal thoughts) with characteristic openness. The initial release, her single No Secrets, was launched in April. But by then there was a mighty secret. The cancer. Later second single, her song Living My Best Life, was released in late spring and she was giving interviews about how she was living her best life, while still secretly dealing with breast cancer. A month later she disclosed her condition, and in the start of summer she had a mastectomy.

She shoots me her best “What the fuck?” expression. “I put out with a song called No Secrets. I’m conducting every press talk, and they ask, ‘What’s happening?’ and I’m, like, ‘Well, not much…’” the singer has just had to postpone shows because she’s awaiting follow-up surgery.

We meet at a photography studio in London. She is dressed in a tan faux-leather coat, blue jeans with detailed white appliqués, off-white boots and oversized specs. Picture rocker vibe meets 1970s Nana Mouskouri. “It seems like I’m in the 1970s and I should have a boyfriend with a big tache.” Like the film, I say, recalling the movie. “That’s what people called me at school!” She beams. Cornish is sharp-witted, unfiltered and direct. She says she has always wanted to try comedy and is hoping to make her initial standup show in the coming year. “I love making people laugh. On stage I basically roast the fans.”

Health Struggles and Diagnosis

The artist was planning an performance at the ceremony when she discovered a mass. “I quickly sought to get it looked at, had an scan, and they said, ‘It looks like nothing; you’ve got really good dense breast tissue.’ And I insisted, ‘But I can feel it. My arm hurts and tingling in my hands whenever I get up.’ And they replied, ‘How about a biopsy?’ The date was March 28, the post-birthday.” It was a weekend eve. The physician told her if it was bad news she’d contact on the start of the week. By then the singer had convinced herself it was okay. The way she describes it, it was simply too inconvenient to receive a diagnosis when she had a busy schedule.

“It was a fortnight prior from launching this thing after years away and an extended break. And she [the doctor] texted and said, ‘Is six okay?’ And I thought, ‘A video call, likely minor.’ So I log in thinking it’s all going to be fine, and she says, ‘Please take a seat.’ You know that sad tone they use? And she says, ‘Unfortunately but your reports have come back as high-grade cancer cells.’” How did you respond? “I replied, ‘Oh, that’s not ideal, is it?. What awful 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 viewed the procedure scary and bizarre. “I hate being put under. They walk you down. In urgent cases you roll down in a bed, but this time I just strolled down with a gown on and my backside out. You feel like you’re in an episode of Black Mirror.” But, Cornish says, she’s been blessed. Without chemo or radio, just the procedure. “Cancer is awful, but yet Thank fuck I found it early. The surgery happened four months ago and my one side now looks like a odd shape.” A further beam. “The nipple was preserved.”

The next operation is for health and appearance. Her boobs, she remarks, are now “asymmetrical. The size doesn’t match. So inconsiderate! I felt, no need to bully me, I’m already having a hard period. Such disrespect! Ironically I said I’d avoid breast surgery because I’ve got perfectionism, and I know they’d never be flawless. My plans were disrupted.”

A History of Health Challenges

Cornish is no stranger to illness. She thinks her attitude toward illness has been so optimistic because she’s experienced in health crises. Many times they occur alongside peak moments, serving as a tap on the shoulder, or shock, to highlight not to be complacent. “Truly, I feel fate says, ‘Things going well? Sit down.’ Since childhood, it has always gone alongside achievements for me; a major or strange event has impacted my body.”

She reminisces to her childhood, already making her debut performing in the London theater in Whistle Down the Wind (she was cast at the age of nine). That’s when she was diagnosed with the cardiac issue WPW, which can cause a tachycardia as well as dizziness and irregular beats. “I was going in and out of rehearsals on an drip, and going back into hospital at night.” She jumps ahead six years, and teenage Jess has entered the girl group Soul Deep while attending the Brit School. “I signed my initial contract, and I had a brain incident. Then when I was planning to release songs in the year 2020 I had a car crash and my throat was injured and I lost my voice for a twelve months.”

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