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

You wouldn’t believe it, the singer states. At that moment gearing up for her comeback record in eight years, ecstatically in love with her newish partner, and finally the mom to a little one after facing fertility challenges for ten years, on top of the world. Then in March she was diagnosed with breast cancer.

The singer-songwriter, birth name J. Cornish, is famous for speaking her mind. The album, the provocatively titled album, was intended as an open book, dealing with every moment of pain she’d experienced since she last recorded music (endometriosis, pregnancy loss, broken romances, gaslighting, suicide) with typical candour. The first single, the song No Secrets, was dropped in April. But by then there was a mighty secret. The illness. Later next release, the upbeat Living My Best Life, was released in late spring and the artist was giving interviews about how she was enjoying life to the fullest, while at the same time dealing with her cancer. Subsequently she disclosed her condition, and in early July she had a mastectomy.

She offers me her best “What the fuck?” glance. “I put out with a song called the track No Secrets. I’m conducting every press talk, and they inquire, ‘Any updates?’ and I respond, ‘Well, not much…’” Cornish has just had to postpone shows because she’s yet to undergo cosmetic procedures.

Our interview takes place at a photography studio in the capital. She is wearing a beige fake-leather jacket, jeans with detailed white appliqués, beige footwear and oversized specs. Think motorcycle style meets 1970s Nana Mouskouri. “It seems like I’m in the 70s and I should have a partner with a mustache.” Like the film, I say, thinking of the picture. “That’s what people called me at school!” She grins. Jessie is quick, irreverent and direct. She says she has always fancied doing comedy and is planning to attempt her first comedy performance in the coming year. “I love making people laugh. On stage I basically roast the audience.”

Personal Battles and News

Cornish was preparing for an slot at the ceremony when she found a lump. “I quickly sought to get it examined, had an ultrasound, and they were, like, ‘It appears fine; your breasts are normal.’ And I responded, ‘However, it’s there. I’ve got an achy arm and pins and needles in my hands whenever I rise.’ And they said, ‘Well, let’s just do a biopsy?’ That was 28 March, the day after my birthday.” It was a Friday. The doctor told her if it was bad news she’d call on the Monday. By then she had assured herself it was okay. The way she explains it, it was simply too inconvenient to face illness when she had a busy schedule.

“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, ‘Is six okay?’ And I thought, ‘A video call, likely minor.’ So I jump on the Zoom thinking it’s all going to be positive, and she informs me, ‘Are you sitting down?.’ You know that sad tone they use? And she continues, ‘I regret to inform you but your test results have shown malignant cells.’” What did you say? “I answered, ‘Oh, that’s not ideal, is it?. That’s not fucking great timing.’ My initial thought was, ‘My child depends on me.’”

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

She viewed the procedure frightening and surreal. “I fear going under. You’re escorted. You know when you have emergency surgery you go on a gurney, but this time I just marched with a medical attire and my rear exposed. Like a dystopian scene.” But, Cornish says, she’s been lucky. No chemo, no radiotherapy, just the op. “Cancer is awful, but however Luckily it was detected early. I had the mastectomy a few months back and my affected breast now appears as a fruit under fabric.” She smiles again. “At least the nipple remains.”

The subsequent surgery is both medical and cosmetic. Her breasts, she remarks, are now “different sizes. They didn’t do an implant as small as my original. How rude! I reflected, don’t add insult to injury, I’m already having a rough time. Such disrespect! Amusingly I said I’d never get my boobs done because I’ve got OCD, and I know they’d never be perfect. My plans were disrupted.”

Past Medical Issues

She is no stranger to illness. She thinks her outlook on her diagnosis has been so optimistic because she’s experienced in health crises. Frequently they align with professional successes, serving as a tap on the shoulder, or punch in the stomach, to remind her not to be complacent. “Truly, I feel life goes, ‘You having a good time? Hold on.’ Since childhood, it has always gone alongside moments of success for me; a serious or unusual issue has impacted my body.”

She reminisces to her childhood, already making her debut featuring in the London theater in Whistle Down the Wind (she was cast at the age of nine years old). That’s when she was diagnosed with the cardiac issue a syndrome, which can cause a rapid pulse as well as dizziness and heart flutters. “I attended rehearsals intermittently on an intravenous line, and returning to the hospital at night.” She jumps ahead half a dozen years, and young Jessica has joined the girl group Soul Deep while studying at the Brit School. “I signed my initial contract, and I had a brain incident. Then when I was about to put out music 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, slow down, I need a moment. At just 17? She nods|agrees
