‘It has taught me to embrace life more’: Jessica Cornish on her health battle, comebacks and conquering the Chinese market

You couldn’t make it up, Jessie J states. There she was preparing for her first album release in eight years, ecstatically in love with her newish partner, and finally the mother of a toddler after facing fertility challenges for a decade, riding high. Suddenly in March she was found to have a breast cancer diagnosis.

The artist, actual name Jessica Cornish, is renowned for telling it as it is. The record, her latest release, was intended as an candid account, tackling every ounce of devastation she’d experienced since she last recorded music (endometriosis, miscarriage, failed relationships, emotional abuse, suicide) with typical candour. The lead track, the song No Secrets, was dropped in April. But by then there remained a major undisclosed truth. Her diagnosis. Later second single, her song Living My Best Life, debuted in late spring and she was talking to press about how she was thriving, while all the while dealing with the disease. Subsequently she disclosed her condition, and in the start of summer she had a mastectomy.

She shoots me her best “Are you kidding?” look. “I come out with a song called No Secrets. I’m giving every interview, and they ask, ‘What’s happening?’ and I answer, ‘Erm, yeah, nothing …’” she has just had to postpone shows because she’s awaiting follow-up surgery.

We’re at a photo studio in London. She is wearing a beige fake-leather jacket, jeans with ornate white designs, cream boots and oversized specs. Imagine motorcycle style meets 1970s Nana Mouskouri. “I feel like I’m in the 70s and I should have a man with facial hair.” Easy Rider, I say, referencing the film. “I was nicknamed that in school!” She grins. Cornish is fast-thinking, bold and direct. She says she has always been interested in humor and is hoping to make her first comedy performance in the coming year. “I love making people laugh. On stage I often tease the audience.”

Health Struggles and Diagnosis

She was getting ready for an appearance at the awards show when she noticed an abnormality. “I quickly sought to get it examined, had an test, and they said, ‘It appears fine; your tissue is healthy.’ And I responded, ‘But I can feel it. I have arm pain and numbness in my fingers whenever I get up.’ And they suggested, ‘We should biopsy it?’ The date was March 28, the day after my birthday.” It was a Friday. The specialist told her if it was serious she’d reach out on the start of the week. By then she had assured herself it was nothing. The way she explains it, it was simply too inconvenient to face illness when she had a busy schedule.

“It was a fortnight prior from launching this thing after a long hiatus and an extended break. And she contacted me and said, ‘Is six okay?’ And I was, like, ‘Oh, it’s a Zoom, it won’t be anything.’ So I join the call thinking it’s all going to be fine, and she informs me, ‘Are you sitting down?.’ That sympathetic voice? And she reveals, ‘I’m so, so sorry but your test results have shown aggressive cancer.’” What was your reaction? “I said, ‘Well, that’s not great. 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 frightening and surreal. “I hate being put under. They lead you. During crises you go on a gurney, but now I just strolled down with a medical attire and my rear exposed. You feel like you’re in an episode of Black Mirror.” But, she notes, she’s been lucky. No chemo, no radiotherapy, just the op. “Cancer sucks, man, but yet Thank fuck I found it early. The surgery happened four months ago and my one side now looks like a odd shape.” She smiles again. “I got to keep the nipple, though.”

The follow-up procedure is for health and appearance. Her breasts, she observes, are now “different sizes. They didn’t do an implant as small as my original. How rude! I thought, no need to bully me, I’m already having a rough time. So rude! Amusingly I said I’d avoid breast surgery because I’ve got obsessive tendencies, and I know they’d never be perfect. My plans were disrupted.”

Past Medical Issues

She is no stranger to illness. She feels her attitude toward illness has been so positive because she’s familiar with medical emergencies. Frequently they align with career highs, functioning as a wake-up call, or blow, to remind her not to assume everything is fine. “Honestly, I feel fate says, ‘Enjoying yourself? Take a seat.’ From a young age, it has always gone alongside high points for me; something severe or obscure has happened to my health.”

She reminisces to her youth, already starting her career featuring in the stage in the production (she was chosen at the age of 9). That’s when she was told about the medical problem a syndrome, which can cause a rapid pulse as well as dizziness and irregular beats. “I rehearsed between visits on an intravenous line, and going back into hospital at night.” She jumps ahead several years, and teenage Jess has joined the girl group Soul Deep while attending the Brit School. “I signed my initial contract, and I had a stroke. Then when I was planning to release songs in 2020 I had a automobile accident and my throat was injured and I lost my voice for a year.”

Oi, I say, slow down, I am overwhelmed. A stroke so young? She nods|agrees
