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

You can’t imagine it, Jessie J remarks. There she was preparing for her new album launch in eight years, ecstatically in love with her recent boyfriend, and finally the mom to a little one after dealing with conception issues for ten years, riding high. Suddenly in spring she was found to have breast cancer.

The musician, real name Jessica Cornish, is famous for speaking her mind. The record, the provocatively titled album, was supposed to be an open book, addressing every bit of hardship she’d endured since she last worked on songs (a gynecological condition, pregnancy loss, broken romances, emotional abuse, mental health struggles) with characteristic openness. The lead track, No Secrets, was launched in the spring. But by then there remained a major undisclosed truth. Her diagnosis. Later second single, Living My Best Life, was released in late spring and she was giving interviews about how she was living her best life, while all the while coping with the disease. Four weeks after she went public, and in early July she underwent breast removal surgery.

She offers me her best “Seriously?” glance. “I release with a song called No Secrets. I’m doing every interview, and they’re, like, ‘What’s happening?’ and I respond, ‘Uh, nothing really’” Cornish has just had to call off performances because she’s awaiting reconstructive surgery.

We’re at a photo studio in the capital. She is dressed in a light brown synthetic jacket, denim trousers with ornate white designs, cream boots and oversized specs. Picture biker chic meets 1970s Nana Mouskouri. “As if I’m in the seventies and I should have a man with facial hair.” Like the film, I say, thinking of the film. “That’s what people called me at school!” She beams. She is sharp-witted, unfiltered and blunt. She says she has always wanted to try comedy and is hoping to make her first comedy performance soon. “I love making people laugh. When performing I often tease the crowd.”

Health Struggles and Diagnosis

She was planning an performance at the awards show when she found a lump. “I quickly sought to get it looked at, had an test, and they said, ‘It seems benign; your breasts are normal.’ And I was, like, ‘But I can feel it. I’ve got an achy arm and tingling in my hands whenever I rise.’ And they replied, ‘Well, let’s just do a biopsy?’ The date was March 28, the day after my birthday.” It was a weekend eve. The physician told her if it was concerning she’d call on the Monday. By then Cornish had convinced herself it was fine. The way she tells it, it was just bad timing to get cancer when she had many commitments.

“Just two weeks before from launching this thing after eight years without an album and no new music. And she [the doctor] texted and said, ‘Can you talk at six?’ And I assumed, ‘A video call, likely minor.’ So I join the call thinking it’s all going to be good, and she goes, ‘You might want to sit.’ That sympathetic voice? And she says, ‘Unfortunately but your reports have come back as malignant cells.’” How did you respond? “I replied, ‘Oh, that’s not ideal, is it?. That’s not fucking great timing.’ My initial thought was, ‘I have to survive for my boy.’”

I’ve been labeled difficult for knowing myself

She viewed the procedure terrifying and absurd. “I fear going under. They lead you. You know when you have emergency surgery you are wheeled, but then I just strolled down with a medical attire and my bum hanging out. You feel like you’re in an episode of Black Mirror.” But, Cornish says, she’s been blessed. Without chemo or radio, just the op. “Cancer is awful, but however Luckily it was detected early. The surgery happened recently and my affected breast now resembles a fruit under fabric.” A further beam. “I got to keep the nipple, though.”

The next operation is both medical and cosmetic. Her boobs, she observes, are now “different sizes. The size doesn’t match. That’s impolite! I felt, why make it worse, I’m already having a difficult experience. So rude! It’s funny because I said I’d never get my boobs done because I’ve got perfectionism, and I know they’d never be flawless. Illness changed that.”

Past Medical Issues

She is no stranger to illness. She believes her outlook on her diagnosis has been so positive because she’s used to physical challenges. Frequently they align with career highs, functioning as a wake-up call, or shock, to highlight not to assume everything is fine. “Frankly, I feel fate says, ‘Things going well? Take a seat.’ From a young age, it has consistently accompanied achievements for me; a serious or unusual issue has affected my well-being.”

She reminisces to her youth, already making her debut performing in the stage in Whistle Down the Wind (she was selected at the age of nine). That’s when she was told about the medical problem WPW, which can cause a rapid pulse as well as vertigo and irregular beats. “I attended rehearsals intermittently on an drip, and returning to the hospital at night.” She jumps ahead six years, and teenage Jess has become part of the girl group the group while attending the performing arts school. “I secured a 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 lost my voice for a twelve months.”

Wow, I say, wait, I can’t keep up. A stroke so young? She nods|agrees
