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

You wouldn’t believe it, Jessie J remarks. There she was readying for her new album launch in eight years, ecstatically in love with her newish partner, and at long last the mother of a toddler after dealing with conception issues for a decade, riding high. Suddenly in spring she was found to have breast cancer.

The singer-songwriter, real name J. Cornish, is famous for being brutally honest. The record, Don’t Tease Me With a Good Time, was supposed to be an open book, dealing with every ounce of devastation she’d endured since she last worked on songs (endometrial issues, losing a baby, unsuccessful partnerships, psychological manipulation, mental health struggles) with typical candour. The lead track, the song No Secrets, was launched in April. But by then there was a mighty secret. Her diagnosis. Later next release, her song Living My Best Life, was released in late spring and Cornish was speaking publicly about how she was enjoying life to the fullest, while still secretly living with breast cancer. Four weeks after she disclosed her condition, and in the start of summer she had a mastectomy.

She gives me her best “Are you kidding?” look. “I come out with a song called the track No Secrets. I’m doing every interview, and they inquire, ‘Any updates?’ and I answer, ‘Uh, nothing really’” she has just had to postpone shows because she’s yet to undergo cosmetic procedures.

Our interview takes place at a photography studio in the capital. She is sporting a tan faux-leather coat, denim trousers with elaborate white patches, cream boots and oversized specs. Think rocker vibe meets 70s singer aesthetic. “As if I’m in the seventies and I should have a partner with a mustache.” Like the film, I say, referencing the picture. “I was nicknamed that in school!” She smiles. She is sharp-witted, unfiltered and blunt. She says she has always wanted to try comedy and is hoping to make her first comedy performance in the coming year. “I enjoy humor. When performing I often tease the crowd.”

Health Struggles and Diagnosis

She was planning an slot at the awards show when she found a lump. “I quickly sought to get it examined, had an ultrasound, and they told me, ‘It appears fine; your tissue is healthy.’ And I was, like, ‘But I can feel it. I’ve got an achy arm and pins and needles in my hands whenever I wake up.’ And they replied, ‘How about a biopsy?’ It happened on March 28, the post-birthday.” It was a Friday. The physician told her if it was bad news she’d contact on the start of the week. By then she had assured herself it was fine. The way she tells it, it was inopportune to receive a diagnosis when she had so much on.

“We’re two weeks away from releasing the album after a long hiatus and an extended break. And she [the doctor] texted and said, ‘Is six okay?’ And I was, like, ‘It’s virtual, probably routine.’ So I join the call expecting it’s all going to be positive, and she informs me, ‘You might want to sit.’ That sympathetic voice? And she says, ‘I regret to inform you but your reports have indicated high-grade cancer cells.’” How did you respond? “I replied, ‘Oh, that’s not ideal, is it?. That’s not fucking great timing.’ My initial 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 hate being put under. You’re escorted. You know when you have emergency surgery you are wheeled, but now I just walked with a medical attire and my bum hanging out. Like a dystopian scene.” But, she notes, she’s been lucky. Without chemo or radio, just the surgery. “Cancer sucks, man, but you know what? I’m grateful it was caught soon. I had the mastectomy recently and my right breast now appears as a odd shape.” Another grin. “The nipple was preserved.”

The next operation is therapeutic and aesthetic. Her breasts, she notes, are now “asymmetrical. The implant is larger than before. That’s impolite! I reflected, don’t add insult to injury, I’m already having a difficult experience. How offensive! Ironically I said I’d not undergo augmentation because I’ve got obsessive tendencies, and I know they’d never be flawless. My plans were disrupted.”

Previous Struggles

She is familiar with health problems. She feels her attitude toward illness has been so optimistic because she’s used to medical emergencies. Frequently they align with career highs, functioning as a wake-up call, or shock, to make her recall not to be complacent. “Frankly, I feel life goes, ‘Things going well? Take a seat.’ From a young age, it has often paired with moments of success for me; a serious or unusual issue has impacted my body.”

She takes me back to her childhood, already making her debut starring in the London theater in Whistle Down the Wind (she was cast at the age of 9). That’s when she was told about the cardiac issue Wolff-Parkinson-White syndrome, which can cause a tachycardia as well as vertigo and irregular beats. “I attended rehearsals intermittently on an IV drip, and returning to the hospital at night.” She fast-forwards six years, and 17-year-old Jess has become part of the trio Soul Deep 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 the year 2020 I had a car crash and my voice box shifted and I was unable to vocalize for a year.”

Wow, I say, slow down, I am overwhelmed. A stroke so young? She nods|agrees
