‘It has made me live life more’: Jessie J on cancer, comebacks and cracking China

You can’t imagine it, Jessie J states. There she was gearing up for her new album launch in eight years, blissfully happy with her newish partner, and at long last the mother of a toddler after facing fertility challenges for ten years, on top of the world. Suddenly in spring she was found to have cancer in her breast.

The singer-songwriter, birth name J. Cornish, is renowned for telling it as it is. The LP, her latest release, was intended as an open book, addressing every moment of pain she’d endured since she last worked on songs (endometrial issues, miscarriage, unsuccessful partnerships, psychological manipulation, suicidal thoughts) with her usual frankness. The initial release, her single No Secrets, was launched in the spring. But by then there was a mighty secret. The cancer. Later next release, the upbeat Living My Best Life, came out in May and Cornish was talking to press about how she was living her best life, while at the same time living with her cancer. Subsequently she disclosed her condition, and in early July she had a mastectomy.

She offers me her best “Are you kidding?” expression. “I put out with a song called the track No Secrets. I’m conducting every media appearance, and they ask, ‘What’s happening?’ and I’m, like, ‘Well, not much…’” Cornish has just had to postpone shows because she’s awaiting follow-up surgery.

We meet at a photo studio in London. She is wearing a tan faux-leather coat, denim trousers with detailed white appliqués, cream boots and oversized specs. Think motorcycle style meets 1970s Nana Mouskouri. “It seems like I’m in the 70s and I should have a boyfriend with a big tache.” Easy Rider, I say, recalling the movie. “I was nicknamed that in school!” She beams. Jessie is quick, unfiltered and blunt. She says she has always wanted to try comedy and is planning to attempt her first comedy performance soon. “I like entertaining. During performances I often tease the audience.”

Health Struggles and Diagnosis

Cornish was preparing for an slot at the awards show when she noticed an abnormality. “I immediately went to get it examined, had an test, and they said, ‘It seems benign; you’ve got really good dense breast tissue.’ And I was, like, ‘But I can feel it. I have arm pain and tingling in my hands whenever I wake up.’ And they suggested, ‘Well, let’s just do a biopsy?’ It happened on March 28, the post-birthday.” It was a weekend eve. The physician told her if it was concerning she’d reach out on the start of the week. By then the singer had persuaded herself it was nothing. The way she tells it, it was simply too inconvenient to get cancer when she had so much on.

“We’re two weeks away from releasing the album after a long hiatus and four years without a single. And she contacted me and said, ‘Are you free at six?’ And I thought, ‘It’s virtual, probably routine.’ So I log in expecting it’s all going to be fine, and she informs me, ‘Please take a seat.’ You know that sad tone they use? And she says, ‘I’m so, so sorry but your test results have indicated malignant cells.’” What did you say? “I replied, ‘Oh, that’s not ideal, is it?. That’s not fucking great timing.’ The first thing I thought was, ‘My child depends on me.’”

Some men find me challenging due to my self-awareness

She found the surgery scary and bizarre. “I hate being put under. They walk you down. During crises you are wheeled, but this time I just strolled down with a hospital gown and my backside out. Like a dystopian scene.” But, Cornish says, she’s been blessed. No chemotherapy or radiation, just the op. “It’s terrible, but you know what? Thank fuck I found it early. I had the mastectomy four months ago and my right breast now appears as a odd shape.” Another grin. “The nipple was preserved.”

The follow-up procedure is therapeutic and aesthetic. Her chest, she remarks, are now “uneven. The size doesn’t match. So inconsiderate! I thought, no need to bully me, I’m already having a rough time. So rude! Amusingly I said I’d never get my boobs done because I’ve got OCD, and I know they’d never be flawless. Illness changed that.”

A History of Health Challenges

Cornish is familiar with health problems. She thinks her perspective on the cancer has been so upbeat because she’s used to physical challenges. Many times they occur alongside career highs, serving as a tap on the shoulder, or blow, to remind her not to take anything for granted. “Frankly, I feel fate says, ‘You having a good time? Take a seat.’ Ever since I was a child, it has often paired with achievements for me; a major or strange event has impacted my body.”

She reminisces to her 11-year-old self, already beginning performing in the West End in a musical (she was cast at the age of 9). That’s when she was found to have the medical problem Wolff-Parkinson-White syndrome, which can cause a rapid pulse as well as dizziness and irregular beats. “I attended rehearsals intermittently on an intravenous line, and being readmitted at night.” She skips forward several years, and teenage Jess has joined the girl group the group while attending the academy. “I just got my first record deal, and I had a cerebral event. Then when I was ready to debut in 2020 I had a collision and my throat was injured and I couldn’t sing for a year.”

Oi, I say, slow down, I can’t keep up. You really had a stroke at 17? She nods|agrees
