‘It has pushed me to live more fully’: Jessie J on cancer, comebacks and cracking China

You couldn’t make it up, the singer says. There she was gearing up for her new album launch in eight years, deeply enamored with her newish partner, and finally the mom to a little one after facing fertility challenges for ten years, riding high. Then in March she was found to have breast cancer.

The artist, actual name J. Cornish, is renowned for being brutally honest. The LP, the provocatively titled album, was supposed to be an open book, addressing every ounce of devastation she’d experienced since she last worked on songs (endometriosis, pregnancy loss, unsuccessful partnerships, gaslighting, mental health struggles) with her usual frankness. The initial release, No Secrets, was launched in the spring. But by then there was a mighty secret. The illness. Then follow-up track, her song 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 breast cancer. Four weeks after she went public, and in July she received surgical treatment.

She shoots me her best “Seriously?” look. “I come out with a song called the track No Secrets. I’m doing every media appearance, and they’re, like, ‘Any updates?’ and I answer, ‘Well, not much…’” the singer has just had to call off performances because she’s yet to undergo reconstructive surgery.

Our interview takes place at a studio in London. She is sporting a light brown synthetic jacket, blue jeans with ornate white designs, beige footwear and big frames. Picture rocker vibe meets vintage look. “I feel like I’m in the 70s and I should have a partner with a mustache.” Easy Rider, I say, thinking of the picture. “I was nicknamed that in school!” She grins. Cornish is quick, unfiltered and blunt. She says she has always been interested in humor and is hoping to make her first comedy performance next year. “I love making people laugh. On stage I often tease the audience.”

Health Struggles and Diagnosis

The artist was preparing for an appearance at the awards show when she discovered a mass. “I promptly visited to get it checked, had an ultrasound, and they said, ‘It appears fine; your tissue is healthy.’ And I insisted, ‘But I can feel it. I have arm pain and numbness in my fingers whenever I rise.’ And they suggested, ‘Well, let’s just do a biopsy?’ It happened on March 28, the following my birthday.” It was a Friday. The doctor told her if it was bad news she’d call on the start of the week. By then the singer had assured herself it was okay. The way she tells it, it was simply too inconvenient to get cancer when she had many commitments.

“Just two weeks before from debuting the project after eight years without an album and an extended break. And she [the doctor] texted and said, ‘Can you talk at six?’ And I thought, ‘A video call, likely minor.’ So I log in thinking it’s all going to be positive, and she says, ‘Please take a seat.’ You know that sad tone they use? And she continues, ‘I’m so, so sorry but your reports have come back as malignant cells.’” How did you respond? “I answered, ‘Well, that’s not great. That’s not fucking great timing.’ My initial thought was, ‘I can’t die because my son needs me.’”

Men have called me difficult because I’m a strong person who understands who I am

She considered the operation frightening and surreal. “I dislike anesthesia. You’re escorted. During crises you go on a gurney, but then I just strolled down with a hospital gown and my rear exposed. You feel like you’re in an episode of Black Mirror.” But, she adds, she’s been fortunate. Without chemo or radio, just the op. “Cancer is awful, but however I’m grateful it was caught soon. I had the mastectomy recently and my one side now appears as a odd shape.” A further beam. “The nipple was preserved.”

The subsequent surgery is both medical and cosmetic. Her chest, she notes, are now “different sizes. The size doesn’t match. How rude! I reflected, why make it worse, I’m already having a difficult experience. Such disrespect! Ironically I said I’d not undergo augmentation because I’ve got obsessive tendencies, and I know they’d never be ideal. Cancer ruined that plan.”

Previous Struggles

Cornish is no stranger to illness. She thinks her outlook on her diagnosis has been so upbeat because she’s experienced in health crises. Many times they occur alongside career highs, functioning as a wake-up call, or punch in the stomach, to highlight not to be complacent. “Frankly, I feel fate says, ‘Things going well? Sit down.’ Since childhood, it has consistently accompanied high points for me; a major or strange event has impacted my body.”

She takes me back to her 11-year-old self, already starting her career performing in the West End in a musical (she was cast at the age of nine). That’s when she was found to have the cardiac issue a syndrome, which can cause a fast heartbeat as well as dizziness and heart flutters. “I was going in and out of rehearsals on an IV drip, and being readmitted at night.” She fast-forwards six years, and teenage Jess has entered the trio Soul Deep while studying at the performing arts school. “I just got my first record deal, and I had a brain incident. Then when I was about to put out music in 2020 I had a collision and my throat was injured and I couldn’t sing for a year.”

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