‘It has made me live life more’: Jessica Cornish on cancer, comebacks and conquering the Chinese market

You wouldn’t believe it, Jessie J states. At that moment gearing up for her first album release in nearly a decade, ecstatically in love with her recent boyfriend, and at long last the mom to a little one after dealing with conception issues for a decade, on top of the world. Suddenly in spring she was diagnosed with breast cancer.

The artist, real name Jessica Cornish, is famous for being brutally honest. The album, her latest release, was intended as an candid account, tackling every ounce of devastation she’d experienced since she last recorded music (endometrial issues, pregnancy loss, failed relationships, psychological manipulation, suicide) with typical candour. The first single, the song No Secrets, was released in April. But by then there was a mighty secret. Her diagnosis. Then next release, Living My Best Life, debuted in late spring and the artist was talking to press about how she was thriving, while all the while coping with her cancer. Subsequently she disclosed her condition, and in early July she had a mastectomy.

She shoots me her best “What the fuck?” look. “I come out with a song called No Secrets. I’m giving every press talk, and they ask, ‘So what’s new with you?’ and I respond, ‘Uh, nothing really’” she has just had to cancel tour dates because she’s still waiting for cosmetic procedures.

We meet at a photo studio in the capital. She is sporting a beige fake-leather jacket, denim trousers with ornate white designs, cream boots and oversized specs. Picture motorcycle style meets 1970s Nana Mouskouri. “I feel like I’m in the 1970s and I should have a partner with a mustache.” Like the film, I say, recalling the film. “That’s what people called me at school!” She smiles. Jessie is sharp-witted, bold and direct. She says she has always wanted to try comedy and is planning to attempt her standup debut next year. “I love making people laugh. When performing I frequently joke about the audience.”

Health Struggles and Diagnosis

She was getting ready for an performance at the Baftas when she discovered a mass. “I quickly sought to get it checked, had an ultrasound, and they said, ‘It seems benign; your breasts are normal.’ And I responded, ‘However, it’s there. I’ve got an achy arm and tingling in my hands whenever I get up.’ And they suggested, ‘Well, let’s just do a biopsy?’ It happened on March 28, the day after my birthday.” It was a Friday. The doctor told her if it was serious she’d contact on the start of the week. By then the singer had assured herself it was fine. The way she describes it, it was inopportune to face illness when she had many commitments.

“Just two weeks before from debuting the project after years away and an extended break. And she [the doctor] texted and said, ‘Can you talk at six?’ And I thought, ‘It’s virtual, probably routine.’ So I jump on the Zoom thinking it’s all going to be good, and she informs me, ‘You might want to sit.’ You know that sad tone they use? And she says, ‘I’m so, so sorry but your test results have shown aggressive cancer.’” What did you say? “I replied, ‘Well, that’s not great. What awful timing.’ The first thing I thought 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 frightening and surreal. “I hate being put under. They walk you down. During crises you go on a gurney, but now I just strolled down with a hospital gown and my backside out. You feel like you’re in an episode of Black Mirror.” But, Cornish says, she’s been blessed. No chemotherapy or radiation, just the surgery. “Cancer sucks, man, but yet Luckily it was detected early. I had the mastectomy recently and my affected breast now appears as a odd shape.” She smiles again. “I got to keep the nipple, though.”

The subsequent surgery is both medical and cosmetic. Her breasts, she remarks, are now “asymmetrical. The size doesn’t match. So inconsiderate! I thought, why make it worse, I’m already having a hard period. So rude! Ironically I said I’d never get my boobs done because I’ve got obsessive tendencies, and I know they’d never be ideal. My plans were disrupted.”

Past Medical Issues

She is no stranger to illness. She believes her perspective on the cancer has been so upbeat because she’s used to medical emergencies. Frequently they align with professional successes, functioning as a wake-up call, or blow, to highlight not to be complacent. “Frankly, I feel fate says, ‘Enjoying yourself? Sit down.’ From a young age, it has often paired with high points for me; something severe or obscure has affected my well-being.”

She recalls to her childhood, already beginning featuring in the West End in a musical (she was cast at the age of 9). That’s when she was found to have the heart condition a syndrome, which can cause a tachycardia as well as vertigo and irregular beats. “I attended rehearsals intermittently on an intravenous line, and returning to the hospital at night.” She skips forward six years, and young Jessica has become part of the female band the group while studying at the performing arts school. “I signed my initial contract, and I had a brain incident. Then when I was planning to release songs in recently I had a collision and my larynx moved up and I was unable to vocalize for a twelve months.”

Hey, I say, slow down, I am overwhelmed. A stroke so young? She nods|agrees
