‘It has taught me to embrace life more’: Jessie J on cancer, career returns and conquering the Chinese market

You couldn’t make it up, the singer remarks. There she was gearing up for her comeback record in eight years, ecstatically in love with her recent boyfriend, and finally the mother of a toddler after facing fertility challenges for ten years, riding high. Suddenly in March she was diagnosed with breast cancer.

The singer-songwriter, actual name Jess Cornish, is renowned for speaking her mind. The LP, her latest release, was supposed to be an transparent story, addressing every bit of hardship she’d experienced since she last recorded music (endometrial issues, losing a baby, unsuccessful partnerships, emotional abuse, mental health struggles) with her usual frankness. The first single, No Secrets, was launched in the spring. But by then there remained a major undisclosed truth. The cancer. Later follow-up track, the upbeat Living My Best Life, debuted in late spring and the artist was speaking publicly about how she was enjoying life to the fullest, while at the same time dealing with the disease. A month later she went public, and in the start of summer she underwent breast removal surgery.

She offers me her best “Are you kidding?” expression. “I put out with a song called No Secrets. I’m doing every press talk, and they’re, like, ‘Any updates?’ and I’m, like, ‘Well, not much…’” the singer has just had to call off performances because she’s still waiting for cosmetic procedures.

We meet at a studio in London. She is wearing a light brown synthetic jacket, jeans with detailed white appliqués, beige footwear and large glasses. Think motorcycle style meets 1970s Nana Mouskouri. “I feel like I’m in the seventies and I should have a partner with a mustache.” Easy Rider, I say, thinking of the film. “They used to call me that!” She beams. She is sharp-witted, irreverent and blunt. She says she has always wanted to try comedy and is hoping to make her initial standup show next year. “I love making people laugh. On stage I basically roast the crowd.”

Medical Challenges and Discovery

Cornish was getting ready for an appearance at the ceremony when she found a lump. “I immediately went to get it looked at, had an test, and they said, ‘It appears fine; your breasts are normal.’ And I responded, ‘But I can feel it. I have arm pain 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 Friday. The doctor told her if it was concerning she’d call on the Monday. By then she had assured herself it was nothing. The way she tells it, it was just bad timing to get cancer when she had many commitments.

“It was a fortnight prior from releasing the album after years away and an extended break. And the doctor messaged and said, ‘Can you talk at six?’ And I was, like, ‘A video call, likely minor.’ So I jump on the Zoom thinking it’s all going to be good, and she informs me, ‘Please take a seat.’ The solemn tone? And she says, ‘I’m so, so sorry but your reports have indicated malignant cells.’” How did you respond? “I answered, ‘That’s unfortunate. What awful timing.’ The first thing I thought was, ‘I can’t die because my son needs me.’”

Men have called me difficult because I’m a strong person who understands who I am

She viewed the procedure scary and bizarre. “I fear going under. They lead you. In urgent cases you roll down in a bed, but now I just marched with a medical attire and my rear exposed. Like a dystopian scene.” But, Cornish says, she’s been fortunate. Without chemo or radio, just the procedure. “Cancer sucks, man, but you know what? Luckily it was detected early. The surgery happened a few months back and my affected breast now appears as a fruit under fabric.” She smiles again. “The nipple was preserved.”

The next operation is both medical and cosmetic. Her chest, she notes, are now “uneven. The size doesn’t match. That’s impolite! I felt, don’t add insult to injury, I’m already having a hard period. So rude! Ironically I said I’d not undergo augmentation because I’ve got OCD, and I know they’d never be flawless. My plans were disrupted.”

Previous Struggles

She is accustomed to medical issues. She feels her outlook on her diagnosis has been so positive because she’s used to physical challenges. Frequently they align with professional successes, acting as a reminder, or punch in the stomach, to remind her not to take anything for granted. “Honestly, I feel fate says, ‘You having a good time? Take a seat.’ Ever since I was a child, it has often paired with achievements for me; something severe or obscure has affected my well-being.”

She takes me back to her childhood, already starting her career featuring in the London theater in the production (she was cast at the age of 9). That’s when she was found to have the cardiac issue WPW, which can cause a rapid pulse as well as dizziness and heart flutters. “I was going in and out of rehearsals on an drip, and going back into hospital at night.” She skips forward half a dozen years, and young Jessica has become part of the female band the group while attending the Brit School. “I just got my first record deal, and I had a cerebral event. Then when I was about to put out music in 2020 I had a car crash and my larynx moved up and I couldn’t sing for a long period.”

Hey, I say, hold on, I need a moment. At just 17? She nods|agrees
