‘It has made me live life more’: Jessie J on cancer, 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 nearly a decade, ecstatically in love with her current love, and at long last the parent to a young child after facing fertility challenges for a decade, feeling invincible. Suddenly in March she was told she had a breast cancer diagnosis.

The musician, actual name J. Cornish, is renowned for being brutally honest. The record, Don’t Tease Me With a Good Time, was meant as an transparent story, addressing every ounce of devastation she’d faced since she last worked on songs (a gynecological condition, pregnancy loss, broken romances, gaslighting, suicide) with typical candour. The lead track, No Secrets, was dropped in the spring. But by then there was a mighty secret. Her diagnosis. Later follow-up track, Living My Best Life, came out in late spring and she was speaking publicly about how she was enjoying life to the fullest, while at the same time living with the disease. Four weeks after she disclosed her condition, and in July she received surgical treatment.

She offers me her best “What the fuck?” expression. “I come out with a song called No Secrets. I’m doing every interview, and they’re, like, ‘Any updates?’ and I’m, like, ‘Well, not much…’” she has just had to postpone shows because she’s yet to undergo cosmetic procedures.

We’re at a photo studio in the capital. She is dressed in a light brown synthetic jacket, jeans with elaborate white patches, beige footwear and large glasses. Think rocker vibe meets vintage look. “It seems like I’m in the 70s and I should have a man with facial hair.” Easy Rider, I say, referencing the movie. “They used to call me that!” She beams. Cornish is fast-thinking, unfiltered and direct. She says she has always wanted to try comedy and is aiming for her initial standup show next year. “I like entertaining. When performing I frequently joke about the crowd.”

Personal Battles and News

The artist was preparing for an appearance at the awards show when she noticed an abnormality. “I quickly sought to get it looked at, had an test, and they said, ‘It looks like nothing; your breasts are normal.’ And I insisted, ‘Yet I sense it. I have arm pain and numbness in my fingers whenever I rise.’ And they replied, ‘We should biopsy it?’ The date was March 28, the day after my birthday.” It was a Friday. The physician told her if it was bad news she’d contact on the Monday. By then Cornish had assured herself it was nothing. The way she explains it, it was simply too inconvenient to receive a diagnosis when she had so much on.

“It was a fortnight prior from releasing the album after eight years without an album and an extended break. And she contacted me and said, ‘Are you free at six?’ And I thought, ‘It’s virtual, probably routine.’ So I jump on the Zoom believing it’s all going to be fine, and she says, ‘Please take a seat.’ You know that sad tone they use? And she continues, ‘Unfortunately but your biopsy results have indicated aggressive cancer.’” How did you respond? “I said, ‘Oh, that’s not ideal, is it?. What awful timing.’ The first thing I thought was, ‘I have to survive for my boy.’”

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

She found the surgery frightening and surreal. “I hate being put under. They walk you down. During crises you are wheeled, but now I just strolled down with a medical attire and my bum hanging out. It felt surreal.” But, she adds, she’s been lucky. Without chemo or radio, just the procedure. “Cancer is awful, but you know what? Luckily it was detected early. I had the mastectomy four months ago and my affected breast now looks like a odd shape.” Another grin. “The nipple was preserved.”

The follow-up procedure is both medical and cosmetic. Her boobs, she observes, are now “asymmetrical. They didn’t do an implant as small as my original. That’s impolite! I felt, why make it worse, I’m already having a rough time. So rude! Ironically I said I’d avoid breast surgery because I’ve got OCD, and I know they’d never be ideal. My plans were disrupted.”

Previous Struggles

Cornish is accustomed to medical issues. She feels her outlook on her diagnosis has been so upbeat because she’s experienced in physical challenges. Frequently they align with peak moments, serving as a tap on the shoulder, or shock, to highlight not to assume everything is fine. “Truly, I feel life goes, ‘Enjoying yourself? Sit down.’ From a young age, it has often paired with moments of success for me; a serious or unusual issue has impacted my body.”

She reminisces to her childhood, already beginning featuring in the West End in Whistle Down the Wind (she was selected at the age of 9). That’s when she was found to have the cardiac issue a syndrome, which can cause a rapid pulse as well as vertigo and heart flutters. “I rehearsed between visits on an IV drip, and returning to the hospital at night.” She jumps ahead several years, and 17-year-old Jess has become part of the female band Soul Deep while studying at the performing arts school. “I just got my first record deal, and I had a cerebral event. Then when I was ready to debut in 2020 I had a collision and my voice box shifted and I lost my voice for a twelve months.”

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