‘It has made me live life more’: Jessie J on her health battle, comebacks and conquering the Chinese market

You wouldn’t believe it, Jessie J states. At that moment gearing up for her new album launch in eight years, ecstatically in love with her recent boyfriend, and finally the mother of a toddler after facing fertility challenges for a decade, on top of the world. Suddenly in spring she was diagnosed with a breast cancer diagnosis.

The singer-songwriter, birth name Jessica Cornish, is known for telling it as it is. The record, Don’t Tease Me With a Good Time, was meant as an transparent story, tackling every moment of pain she’d endured since she last worked on songs (endometrial issues, losing a baby, unsuccessful partnerships, gaslighting, suicidal thoughts) with typical candour. The lead track, her single No Secrets, was dropped in the spring. But by then there remained a major undisclosed truth. The illness. Later next release, Living My Best Life, was released in May and the artist was giving interviews about how she was enjoying life to the fullest, while all the while dealing with her cancer. A month later she disclosed her condition, and in July she received surgical treatment.

She shoots me her best “Are you kidding?” look. “I come out with a song called the track No Secrets. I’m doing every press talk, and they ask, ‘What’s happening?’ and I answer, ‘Uh, nothing really’” the singer has just had to call off performances because she’s awaiting follow-up surgery.

Our interview takes place at a photography studio in London. She is dressed in a beige fake-leather jacket, blue jeans with ornate white designs, off-white boots and big frames. Think biker chic meets 70s singer aesthetic. “I feel like I’m in the seventies and I should have a boyfriend with a big tache.” Like the film, I say, recalling the picture. “That’s what people called me at school!” She smiles. Cornish is sharp-witted, irreverent and filter-free. She says she has always been interested in humor and is planning to attempt her standup debut next year. “I love making people laugh. During performances I often tease the audience.”

Health Struggles and Diagnosis

The artist was preparing for an appearance at the awards show when she found a lump. “I quickly sought to get it looked at, had an test, and they told me, ‘It appears fine; you’ve got really good dense breast tissue.’ And I insisted, ‘Yet I sense it. I’ve got an achy arm and pins and needles in my hands whenever I wake up.’ And they said, ‘We should biopsy it?’ The date was March 28, the post-birthday.” It was a Friday. The physician told her if it was concerning she’d call on the Monday. By then the singer had persuaded herself it was nothing. The way she describes it, it was just bad timing to get cancer when she had many commitments.

“We’re two weeks away from releasing the album after years away and four years without a single. And the doctor messaged and said, ‘Is six okay?’ And I was, like, ‘A video call, likely minor.’ So I jump on the Zoom 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 regret to inform you but your test results have indicated high-grade cancer cells.’” What was your reaction? “I said, ‘Oh, that’s not ideal, is it?. What awful timing.’ The first thing I thought was, ‘I can’t die because my son needs me.’”

Some men find me challenging due to my self-awareness

She found the surgery frightening and surreal. “I fear going under. They lead you. You know when you have emergency surgery you go on a gurney, but now I just walked with a hospital gown and my bum hanging out. You feel like you’re in an episode of Black Mirror.” But, she adds, she’s been lucky. No chemo, no radiotherapy, just the surgery. “It’s terrible, but you know what? I’m grateful it was caught soon. The surgery happened four months ago and my affected breast now appears as a odd shape.” A further beam. “The nipple was preserved.”

The follow-up procedure is therapeutic and aesthetic. Her boobs, she remarks, are now “different sizes. The size doesn’t match. How rude! I reflected, why make it worse, I’m already having a rough time. How offensive! Ironically I said I’d not undergo augmentation because I’ve got OCD, and I know they’d never be perfect. Cancer ruined that plan.”

Previous Struggles

She is accustomed to medical issues. She thinks her attitude toward illness has been so positive because she’s familiar with health crises. They have often coincided with professional successes, serving as a tap on the shoulder, or blow, to remind her not to take anything for granted. “Honestly, I feel the universe whispers, ‘You having a good time? Hold on.’ Ever since I was a child, it has often paired with achievements for me; a serious or unusual issue has happened to my health.”

She takes me back to her childhood, already beginning starring in the West End in a musical (she was selected at the age of 9). 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 irregular beats. “I attended rehearsals intermittently on an IV drip, and being readmitted at night.” She jumps ahead several years, and young Jessica has become part of the trio Soul Deep while attending the Brit School. “I secured a deal, and I had a brain incident. Then when I was ready to debut in recently I had a collision and my throat was injured and I was unable to vocalize for a year.”

Wow, I say, slow down, I am overwhelmed. At just 17? She nods|agrees
