‘It has pushed me to live more fully’: Jessie J on her health battle, comebacks and cracking China

You couldn’t make it up, Jessie J remarks. There she was gearing up for her new album launch in eight years, blissfully happy with her newish partner, and finally the mom to a little one after facing fertility challenges for a decade, feeling invincible. Suddenly in March she was found to have cancer in her breast.

The musician, birth name J. Cornish, is known for being brutally honest. The LP, Don’t Tease Me With a Good Time, was meant as an transparent story, dealing with every ounce of devastation she’d endured since she last worked on songs (endometriosis, miscarriage, failed relationships, gaslighting, suicide) with her usual frankness. The initial release, No Secrets, was dropped in the spring. But by then there remained a major undisclosed truth. Her diagnosis. Then follow-up track, Living My Best Life, was released in May and she was talking to press about how she was living her best life, while all the while living with the disease. A month later she went public, and in early July she underwent breast removal surgery.

She offers me her best “Are you kidding?” glance. “I release with a song called No Secrets. I’m giving every interview, and they ask, ‘What’s happening?’ and I’m, like, ‘Uh, nothing really’” she has just had to call off performances because she’s yet to undergo cosmetic procedures.

We meet at a studio in the capital. She is wearing a light brown synthetic jacket, blue jeans with ornate white designs, off-white boots and big frames. Picture biker chic meets 1970s Nana Mouskouri. “As if I’m in the 1970s and I should have a partner with a mustache.” Easy Rider, I say, referencing the picture. “I was nicknamed that in school!” She smiles. Cornish is quick, bold and direct. She says she has always been interested in humor and is planning to attempt her first comedy performance soon. “I enjoy humor. On stage I often tease the crowd.”

Medical Challenges and Discovery

Cornish was preparing for an performance at the Baftas when she discovered a mass. “I quickly sought to get it examined, had an test, and they said, ‘It looks like nothing; your tissue is healthy.’ And I was, like, ‘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?’ It happened on March 28, the following my birthday.” It was a Friday. The physician told her if it was serious she’d reach out on the start of the week. By then Cornish had convinced herself it was nothing. The way she explains it, it was just bad timing to get cancer when she had a busy schedule.

“Just two weeks before from releasing the album after a long hiatus and an extended break. And she contacted me and said, ‘Can you talk at six?’ And I was, like, ‘A video call, likely minor.’ So I jump on the Zoom expecting it’s all going to be fine, and she informs me, ‘You might want to sit.’ The solemn tone? And she continues, ‘I regret to inform you but your test results have come back as malignant cells.’” What was your reaction? “I answered, ‘Oh, that’s not ideal, is it?. That’s not fucking great 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 viewed the procedure scary and bizarre. “I fear going under. They walk you down. You know when you have emergency surgery you go on a gurney, but this time I just strolled down with a medical attire and my bum hanging out. You feel like you’re in an episode of Black Mirror.” But, she notes, she’s been blessed. No chemotherapy or radiation, just the procedure. “Cancer sucks, man, but yet Thank fuck I found it early. The surgery happened recently and my affected breast now appears as a grapefruit under a tight bedsheet.” Another grin. “I got to keep the nipple, though.”

The subsequent surgery is both medical and cosmetic. Her chest, she observes, are now “asymmetrical. The implant is larger than before. So inconsiderate! I thought, don’t add insult to injury, I’m already having a difficult experience. Such disrespect! Ironically I said I’d avoid breast surgery because I’ve got OCD, and I know they’d never be ideal. Cancer ruined that plan.”

Previous Struggles

Cornish is no stranger to illness. She believes her perspective on the cancer has been so optimistic because she’s familiar with physical challenges. They have often coincided with professional successes, serving as a tap on the shoulder, or blow, to highlight not to take anything for granted. “Honestly, I feel life goes, ‘Enjoying yourself? Take a seat.’ Since childhood, it has often paired with achievements for me; a serious or unusual issue has impacted my body.”

She reminisces to her childhood, already making her debut performing in the London theater in Whistle Down the Wind (she was cast at the age of 9). That’s when she was diagnosed with the cardiac issue a syndrome, which can cause a fast heartbeat as well as dizziness and heart flutters. “I attended rehearsals intermittently on an IV drip, and being readmitted at night.” She fast-forwards several years, and teenage Jess has entered the girl group Soul Deep while attending the academy. “I just got my first record deal, and I had a cerebral event. Then when I was planning to release songs in the year 2020 I had a automobile accident and my voice box shifted and I couldn’t sing for a twelve months.”

Hey, I say, wait, I can’t keep up. A stroke so young? She nods|agrees
