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

You can’t imagine it, Jessie J remarks. At that moment readying for her first album release in eight years, deeply enamored with her recent boyfriend, and finally the mom to a little one after dealing with conception issues for a decade, riding high. Suddenly in March she was found to have a breast cancer diagnosis.

The musician, real name Jess Cornish, is famous for speaking her mind. The album, her latest release, was supposed to be an open book, dealing with every ounce of devastation she’d experienced since she last worked on songs (endometrial issues, losing a baby, unsuccessful partnerships, emotional abuse, suicidal thoughts) with characteristic openness. The first single, her single No Secrets, was released in the spring. But by then there remained a major undisclosed truth. Her diagnosis. Then next release, Living My Best Life, debuted in late spring and she was talking to press about how she was living her best life, while all the while living with breast cancer. Four weeks after she disclosed her condition, and in July she had a mastectomy.

She offers me her best “What the fuck?” expression. “I put out with a song called the track No Secrets. I’m doing every press talk, and they’re, like, ‘What’s happening?’ and I’m, like, ‘Uh, nothing really’” Cornish has just had to cancel tour dates because she’s awaiting reconstructive surgery.

Our interview takes place at a photo studio in London. She is wearing a beige fake-leather jacket, blue jeans with elaborate white patches, off-white boots and large glasses. Think biker chic meets 1970s Nana Mouskouri. “As if I’m in the 70s and I should have a boyfriend with a big tache.” Easy Rider, I say, thinking of the film. “I was nicknamed that in school!” She beams. Jessie is fast-thinking, irreverent and direct. She says she has always wanted to try comedy and is hoping to make her standup debut next year. “I like entertaining. When performing I basically roast the fans.”

Health Struggles and Diagnosis

She was planning an slot at the ceremony when she noticed an abnormality. “I promptly visited to get it examined, had an ultrasound, and they said, ‘It seems benign; you’ve got really good dense breast tissue.’ And I insisted, ‘However, it’s there. I’ve got an achy arm and pins and needles in my hands whenever I rise.’ And they suggested, ‘How about a biopsy?’ That was 28 March, the day after my birthday.” It was a weekend eve. The physician told her if it was concerning she’d reach out on the Monday. By then Cornish had assured herself it was fine. The way she tells it, it was just bad timing to face illness when she had so much on.

“It was a fortnight prior from releasing the album after a long hiatus and an extended break. And she contacted me and said, ‘Are you free at six?’ And I assumed, ‘Oh, it’s a Zoom, it won’t be anything.’ So I log in expecting it’s all going to be fine, and she says, ‘Please take a seat.’ The solemn tone? And she reveals, ‘I regret to inform you but your reports have shown high-grade cancer cells.’” What did you say? “I answered, ‘That’s unfortunate. What awful timing.’ The first thing I thought was, ‘I can’t die because my son needs me.’”

I’ve been labeled difficult for knowing myself

She considered the operation terrifying and absurd. “I hate being put under. They walk you down. In urgent cases you are wheeled, but now I just walked with a medical attire and my bum hanging out. Like a dystopian scene.” But, she adds, she’s been blessed. Without chemo or radio, just the procedure. “Cancer is awful, but yet Thank fuck I found it early. The surgery happened recently and my right breast now appears as a odd shape.” Another grin. “The nipple was preserved.”

The next operation is for health and appearance. Her boobs, she remarks, are now “asymmetrical. The size doesn’t match. So inconsiderate! I thought, don’t add insult to injury, I’m already having a hard period. How offensive! Ironically I said I’d not undergo augmentation because I’ve got OCD, and I know they’d never be perfect. My plans were disrupted.”

Previous Struggles

The singer is no stranger to illness. She believes her attitude toward illness has been so optimistic because she’s experienced in physical challenges. Many times they occur alongside career highs, functioning as a wake-up call, or punch in the stomach, to remind her not to assume everything is fine. “Honestly, I feel life goes, ‘You having a good time? Take a seat.’ Since childhood, it has consistently accompanied moments of success for me; a serious or unusual issue has impacted my body.”

She takes me back to her childhood, already starting her career performing in the West End in a musical (she was chosen at the age of 9). That’s when she was found to have the medical problem a syndrome, which can cause a rapid pulse as well as vertigo and palpitations. “I rehearsed between visits on an IV drip, and going back into hospital at night.” She jumps ahead six years, and teenage Jess has joined the girl group Soul Deep while enrolled in the Brit School. “I just got my first record deal, and I had a brain incident. Then when I was about to put out music in the year 2020 I had a automobile accident and my throat was injured and I couldn’t sing for a long period.”

Wow, I say, wait, I need a moment. A stroke so young? She nods|agrees
