‘It has made me live life more’: Jessie J on her health battle, career returns and cracking China

You couldn’t make it up, Jessie J remarks. At that moment preparing for her new album launch in eight years, ecstatically in love with her newish partner, and at long last the mother of a toddler after facing fertility challenges for a decade, on top of the world. Then in spring she was told she had cancer in her breast.

The musician, actual name Jess Cornish, is renowned for telling it as it is. The record, the provocatively titled album, was meant as an open book, addressing every bit of hardship she’d endured since she last worked on songs (a gynecological condition, miscarriage, unsuccessful partnerships, psychological manipulation, suicide) with typical candour. The first single, No Secrets, was released in the spring. But by then there remained a major undisclosed truth. The cancer. Then next release, her song Living My Best Life, was released in May and Cornish was speaking publicly about how she was living her best life, while still secretly dealing with breast cancer. Subsequently she shared the news, and in July she received surgical treatment.

She offers me her best “What the fuck?” expression. “I put out with a song called No Secrets. I’m conducting every media appearance, and they inquire, ‘What’s happening?’ and I’m, like, ‘Erm, yeah, nothing …’” Cornish has just had to call off performances because she’s yet to undergo follow-up surgery.

We’re at a studio in the capital. She is dressed in a beige fake-leather jacket, jeans with elaborate white patches, cream boots and big frames. Picture rocker vibe meets 1970s Nana Mouskouri. “As if I’m in the seventies and I should have a partner with a mustache.” Easy Rider, I say, thinking of the picture. “They used to call me that!” She beams. Cornish is sharp-witted, unfiltered and filter-free. She says she has always fancied doing comedy and is hoping to make her first comedy performance in the coming year. “I like entertaining. During performances I often tease the crowd.”

Medical Challenges and Discovery

She was getting ready for an appearance at the awards show when she discovered a mass. “I promptly visited to get it checked, had an test, and they were, like, ‘It appears fine; your tissue is healthy.’ And I insisted, ‘Yet I sense it. My arm hurts and tingling in my hands whenever I wake up.’ And they suggested, ‘Well, let’s just do a biopsy?’ That was 28 March, the following my birthday.” It was a Friday. The specialist told her if it was serious she’d contact on the start of the week. By then she had persuaded herself it was okay. The way she describes it, it was inopportune to get cancer when she had many commitments.

“We’re two weeks away from launching this thing after years away and an extended break. And the doctor messaged and said, ‘Are you free at six?’ And I assumed, ‘It’s virtual, probably routine.’ So I join the call thinking it’s all going to be fine, and she says, ‘Are you sitting down?.’ The solemn tone? And she continues, ‘I regret to inform you but your biopsy results have shown high-grade cancer cells.’” How did you respond? “I said, ‘That’s unfortunate. 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. In urgent cases you roll down in a bed, but then I just marched with a medical attire and my rear exposed. It felt surreal.” But, Cornish says, she’s been fortunate. No chemo, no radiotherapy, just the procedure. “Cancer is awful, but yet Thank fuck I found it early. I underwent removal four months ago and my right breast now appears as a grapefruit under a tight bedsheet.” Another grin. “I got to keep the nipple, though.”

The subsequent surgery is for health and appearance. Her boobs, she remarks, are now “uneven. The implant is larger than before. How rude! I reflected, why make it worse, 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 flawless. Illness changed that.”

A History of Health Challenges

The singer is no stranger to illness. She believes her perspective on the cancer has been so upbeat because she’s experienced in health crises. They have often coincided with professional successes, acting as a reminder, or punch in the stomach, to make her recall not to be complacent. “Truly, I feel fate says, ‘You having a good time? Take a seat.’ From a young age, it has often paired with moments of success for me; a serious or unusual issue has affected my well-being.”

She reminisces to her youth, already beginning performing in the London theater in a musical (she was selected at the age of nine). That’s when she was diagnosed with the cardiac issue Wolff-Parkinson-White syndrome, which can cause a rapid pulse as well as dizziness and heart flutters. “I rehearsed between visits on an drip, and going back into hospital at night.” She fast-forwards several years, and young Jessica has entered the girl group Soul Deep while enrolled in the performing arts school. “I just got my first record deal, and I had a stroke. Then when I was ready to debut in 2020 I had a collision and my voice box shifted and I was unable to vocalize for a long period.”

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