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

You couldn’t make it up, Jessie J states. At that moment gearing up for her new album launch in nearly a decade, ecstatically in love with her recent boyfriend, and at long last the parent to a young child after dealing with conception issues for ten years, riding high. Suddenly in March she was told she had cancer in her breast.

The musician, real name Jess Cornish, is known for being brutally honest. The album, her latest release, was intended as an transparent story, tackling every bit of hardship she’d faced since she last made an album (endometrial issues, losing a baby, unsuccessful partnerships, psychological manipulation, mental health struggles) with typical candour. The lead track, her single No Secrets, was released in the spring. But by then there remained a major undisclosed truth. The cancer. Later follow-up track, her song Living My Best Life, came out in May and Cornish was giving interviews about how she was thriving, while still secretly coping with breast cancer. A month later she went public, and in July she had a mastectomy.

She shoots me her best “Are you kidding?” glance. “I put out with a song called the track No Secrets. I’m doing every media appearance, and they inquire, ‘What’s happening?’ and I answer, ‘Uh, nothing really’” she has just had to cancel tour dates because she’s yet to undergo cosmetic procedures.

We meet at a studio in the capital. She is wearing a tan faux-leather coat, blue jeans with detailed white appliqués, cream boots and big frames. Picture rocker vibe meets 1970s Nana Mouskouri. “I feel like I’m in the 1970s and I should have a boyfriend with a big tache.” A biker reference, I say, referencing the picture. “I was nicknamed that in school!” She smiles. Jessie is quick, unfiltered and blunt. She says she has always fancied doing comedy and is aiming for her initial standup show next year. “I enjoy humor. During performances I basically roast the fans.”

Health Struggles and Diagnosis

She was preparing for an performance at the Baftas when she found a lump. “I immediately went to get it looked at, had an ultrasound, and they were, like, ‘It looks like nothing; your tissue is healthy.’ And I responded, ‘Yet I sense it. I’ve got an achy arm and tingling in my hands whenever I get up.’ And they replied, ‘How about a biopsy?’ That was 28 March, the post-birthday.” It was a weekend eve. The specialist told her if it was serious she’d reach out on the Monday. By then Cornish had persuaded herself it was okay. The way she describes it, it was just bad timing to receive a diagnosis when she had so much on.

“Just two weeks before from releasing the album after eight years without an album and an extended break. And she contacted me and said, ‘Is six okay?’ And I was, like, ‘It’s virtual, probably routine.’ So I jump on the Zoom believing it’s all going to be good, and she says, ‘Are you sitting down?.’ The solemn tone? And she says, ‘I regret to inform you but your reports have indicated aggressive cancer.’” How did you respond? “I said, ‘That’s unfortunate. The timing is terrible.’ The first thing I thought was, ‘I have to survive for my boy.’”

Some men find me challenging due to my self-awareness

She considered the operation scary and bizarre. “I dislike anesthesia. You’re escorted. You know when you have emergency surgery you roll down in a bed, but now I just marched with a medical attire and my bum hanging out. You feel like you’re in an episode of Black Mirror.” But, she adds, she’s been blessed. Without chemo or radio, just the surgery. “Cancer is awful, but you know what? Thank fuck I found it early. I had the mastectomy four months ago and my one side now looks like a grapefruit under a tight bedsheet.” Another grin. “I got to keep the nipple, though.”

The next operation is therapeutic and aesthetic. Her breasts, she observes, are now “asymmetrical. They didn’t do an implant as small as my original. So inconsiderate! I reflected, why make it worse, I’m already having a rough time. How offensive! Amusingly I said I’d never get my boobs done because I’ve got OCD, and I know they’d never be ideal. My plans were disrupted.”

A History of Health Challenges

Cornish is no stranger to illness. She thinks her perspective on the cancer has been so upbeat because she’s used to physical challenges. Frequently they align with career highs, functioning as a wake-up call, or shock, to remind her not to assume everything is fine. “Frankly, I feel the universe whispers, ‘Things going well? Sit down.’ Since childhood, it has always gone alongside high points for me; something severe or obscure has impacted my body.”

She takes me back to her childhood, already starting her career starring in the stage in the production (she was chosen at the age of nine years old). That’s when she was found to have the medical problem Wolff-Parkinson-White syndrome, which can cause a tachycardia as well as dizziness and irregular beats. “I rehearsed between visits on an IV drip, and returning to the hospital at night.” She skips forward several years, and young Jessica has entered the trio Soul Deep while enrolled in the academy. “I secured a deal, and I had a brain incident. Then when I was planning to release songs in recently I had a automobile accident and my larynx moved up and I lost my voice for a year.”

Oi, I say, hold on, I am overwhelmed. At just 17? She nods|agrees
