‘It has made me live life more’: Jessica Cornish on her health battle, comebacks and cracking China

You can’t imagine it, Jessie J states. At that moment preparing for her new album launch in eight years, deeply enamored with her newish partner, and finally the parent to a young child after struggling to conceive for a decade, riding high. Suddenly in spring she was found to have a breast cancer diagnosis.

The singer-songwriter, birth name J. Cornish, is famous for speaking her mind. The record, the provocatively titled album, was meant as an transparent story, addressing every bit of hardship she’d experienced since she last recorded music (a gynecological condition, miscarriage, broken romances, gaslighting, suicide) with her usual frankness. The first single, No Secrets, was released in the spring. But by then there remained a major undisclosed truth. The cancer. Then follow-up track, the upbeat Living My Best Life, was released in late spring and she was giving interviews about how she was thriving, while at the same time living with breast cancer. Four weeks after she went public, and in July she received surgical treatment.

She gives me her best “Are you kidding?” look. “I release with a song called the track No Secrets. I’m giving every interview, and they ask, ‘So what’s new with you?’ and I respond, ‘Well, not much…’” the singer has just had to postpone shows because she’s yet to undergo reconstructive surgery.

We meet at a studio in London. She is dressed in a light brown synthetic jacket, denim trousers with ornate white designs, beige footwear and oversized specs. Imagine rocker vibe meets 1970s Nana Mouskouri. “As if I’m in the 1970s 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 grins. She is fast-thinking, irreverent and direct. She says she has always wanted to try comedy and is aiming for her first comedy performance soon. “I enjoy humor. On stage I often tease the audience.”

Medical Challenges and Discovery

She was getting ready for an appearance at the Baftas when she discovered a mass. “I quickly sought to get it checked, had an test, and they said, ‘It looks like nothing; you’ve got really good dense breast tissue.’ And I responded, ‘Yet I sense it. I have arm pain and numbness in my fingers whenever I wake up.’ And they said, ‘Well, let’s just do a biopsy?’ That was 28 March, the following my birthday.” It was a weekend eve. The doctor told her if it was bad news she’d reach out on the start of the week. By then Cornish had assured herself it was nothing. The way she explains it, it was just bad timing to get cancer when she had so much on.

“Just two weeks before from debuting the project after a long hiatus and four years without a single. And she [the doctor] texted and said, ‘Are you free at six?’ And I thought, ‘It’s virtual, probably routine.’ So I join the call believing it’s all going to be good, and she informs me, ‘You might want to sit.’ The solemn tone? And she continues, ‘I’m so, so sorry but your test results have come back as aggressive cancer.’” What was your reaction? “I answered, ‘Oh, that’s not ideal, is it?. The timing is terrible.’ 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 dislike anesthesia. They walk you down. In urgent cases you roll down in a bed, but now I just strolled down with a hospital gown and my backside out. You feel like you’re in an episode of Black Mirror.” But, she adds, she’s been fortunate. No chemo, no radiotherapy, just the op. “Cancer sucks, man, but yet I’m grateful it was caught soon. I had the mastectomy recently and my right breast now appears as a odd shape.” A further beam. “At least the nipple remains.”

The subsequent surgery is for health and appearance. Her boobs, she remarks, are now “different sizes. They didn’t do an implant as small as my original. So inconsiderate! I thought, why make it worse, I’m already having a difficult experience. Such disrespect! Ironically I said I’d never get my boobs done because I’ve got perfectionism, and I know they’d never be flawless. Cancer ruined that plan.”

Previous Struggles

The singer is no stranger to illness. She believes her outlook on her diagnosis has been so upbeat because she’s familiar with physical challenges. Many times they occur alongside peak moments, serving as a tap on the shoulder, or shock, to make her recall not to take anything for granted. “Honestly, I feel the universe whispers, ‘Enjoying yourself? Hold on.’ Ever since I was a child, it has often paired with moments of success for me; something severe or obscure has impacted my body.”

She reminisces to her youth, already beginning featuring in the stage in a musical (she was selected at the age of 9). That’s when she was told about the cardiac issue Wolff-Parkinson-White syndrome, which can cause a rapid pulse as well as lightheadedness and heart flutters. “I attended rehearsals intermittently on an drip, and returning to the hospital at night.” She jumps ahead six years, and young Jessica has joined the girl group Soul Deep while enrolled in the performing arts school. “I secured a deal, and I had a brain incident. Then when I was about to put out music in recently I had a car crash and my voice box shifted and I couldn’t sing for a long period.”

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