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

You can’t imagine it, Jessie J states. There she was gearing up for her first album release in nearly a decade, ecstatically in love with her newish partner, and finally the mother of a toddler after facing fertility challenges for ten years, feeling invincible. Then in spring she was told she had breast cancer.

The artist, real name Jessica Cornish, is famous for speaking her mind. The album, her latest release, was supposed to be an candid account, dealing with every moment of pain she’d faced since she last worked on songs (a gynecological condition, losing a baby, failed relationships, gaslighting, suicide) with her usual frankness. The first single, her single No Secrets, was dropped in the spring. But by then there was a mighty secret. Her diagnosis. Then follow-up track, her song Living My Best Life, was released in late spring and Cornish was giving interviews about how she was enjoying life to the fullest, while at the same time living with the disease. Four weeks after she shared the news, and in early July she underwent breast removal surgery.

She shoots me her best “Seriously?” glance. “I release with a song called No Secrets. I’m conducting every media appearance, and they’re, like, ‘Any updates?’ and I respond, ‘Uh, nothing really’” the singer has just had to postpone shows because she’s still waiting for reconstructive surgery.

Our interview takes place at a photo studio in the capital. She is sporting a beige fake-leather jacket, jeans with ornate white designs, cream boots and big frames. Imagine biker chic meets 70s singer aesthetic. “I feel like I’m in the seventies and I should have a man with facial hair.” Like the film, I say, referencing the movie. “I was nicknamed that in school!” She grins. She is quick, bold and filter-free. She says she has always wanted to try comedy and is aiming for her first comedy performance in the coming year. “I like entertaining. When performing I basically roast the fans.”

Health Struggles and Diagnosis

Cornish was getting ready for an performance at the Baftas when she found a lump. “I quickly sought to get it examined, had an test, 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 get up.’ And they replied, ‘Well, let’s just do a biopsy?’ It happened on March 28, the day after my birthday.” It was a weekend eve. The doctor told her if it was bad news she’d call on the start of the week. By then Cornish had assured herself it was nothing. The way she tells it, it was simply too inconvenient to receive a diagnosis when she had so much on.

“We’re two weeks away from launching this thing after a long hiatus and an extended break. And she contacted me and said, ‘Is six okay?’ And I thought, ‘A video call, likely minor.’ So I jump on the Zoom believing it’s all going to be positive, and she says, ‘Are you sitting down?.’ The solemn tone? And she continues, ‘I regret to inform you but your test results have come back as high-grade cancer cells.’” What was your reaction? “I replied, ‘Oh, that’s not ideal, is it?. What awful timing.’ My initial thought was, ‘I have to survive for my boy.’”

Some men find me challenging due to my self-awareness

She considered the operation frightening and surreal. “I hate being put under. They walk you down. During crises you go on a gurney, but this time I just marched with a gown on and my rear exposed. Like a dystopian scene.” But, she adds, she’s been fortunate. No chemo, no radiotherapy, just the op. “It’s terrible, but however Luckily it was detected early. I had the mastectomy recently and my affected breast now appears as a fruit under fabric.” A further beam. “I got to keep the nipple, though.”

The follow-up procedure is therapeutic and aesthetic. Her chest, she observes, are now “uneven. They didn’t do an implant as small as my original. How rude! I felt, no need to bully me, I’m already having a rough time. Such disrespect! It’s funny because I said I’d not undergo augmentation because I’ve got perfectionism, and I know they’d never be perfect. Cancer ruined that plan.”

Previous Struggles

She is no stranger to illness. She thinks her attitude toward illness has been so upbeat because she’s familiar with physical challenges. Frequently they align with peak moments, serving as a tap on the shoulder, or blow, to highlight not to take anything for granted. “Truly, I feel fate says, ‘You having a good time? Hold on.’ From a young age, it has consistently accompanied moments of success for me; a major or strange event has happened to my health.”

She reminisces to her childhood, already beginning starring 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 heart condition Wolff-Parkinson-White syndrome, which can cause a rapid pulse as well as lightheadedness and irregular beats. “I was going in and out of rehearsals on an intravenous line, and returning to the hospital at night.” She skips forward six years, and 17-year-old Jess has joined the female band Soul Deep while attending the performing arts school. “I just got my first record deal, and I had a cerebral event. Then when I was ready to debut in recently I had a collision and my throat was injured and I lost my voice for a twelve months.”

Hey, I say, hold on, I need a moment. A stroke so young? She nods|agrees
