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

You wouldn’t believe it, Jessie J says. There she was readying for her new album launch in eight years, ecstatically in love with her newish partner, and finally the mother of a toddler after facing fertility challenges for ten years, riding high. Then in spring she was found to have a breast cancer diagnosis.

The musician, actual name Jessica Cornish, is famous for telling it as it is. The record, Don’t Tease Me With a Good Time, was supposed to be an transparent story, dealing with every bit of hardship she’d experienced since she last recorded music (a gynecological condition, pregnancy loss, failed relationships, gaslighting, suicide) with typical candour. The first single, the song No Secrets, was launched in the spring. But by then there remained a major undisclosed truth. Her diagnosis. Later second single, her song Living My Best Life, debuted in May and she was speaking publicly about how she was enjoying life to the fullest, while all the while living with her cancer. Four weeks after she disclosed her condition, and in the start of summer she underwent breast removal surgery.

She gives me her best “What the fuck?” expression. “I come out with a song called No Secrets. I’m doing every media appearance, and they ask, ‘So what’s new with you?’ and I answer, ‘Erm, yeah, nothing …’” she has just had to call off performances because she’s yet to undergo cosmetic procedures.

Our interview takes place at a studio in the capital. She is sporting a tan faux-leather coat, jeans with detailed white appliqués, off-white boots and oversized specs. Imagine biker chic meets 1970s Nana Mouskouri. “It seems like I’m in the seventies and I should have a boyfriend with a big tache.” Like the film, I say, recalling the movie. “They used to call me that!” She beams. She is quick, bold and filter-free. She says she has always fancied doing comedy and is aiming for her standup debut in the coming year. “I like entertaining. During performances I basically roast the audience.”

Health Struggles and Diagnosis

The artist was planning an performance at the Baftas when she noticed an abnormality. “I immediately went to get it checked, 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 wake up.’ And they suggested, ‘Well, let’s just do a biopsy?’ The date was March 28, the following my birthday.” It was a Friday. The specialist told her if it was concerning she’d contact on the Monday. By then she had persuaded herself it was nothing. The way she describes it, it was inopportune to receive a diagnosis when she had many commitments.

“It was a fortnight prior from releasing the album after years away and an extended break. And she [the doctor] texted and said, ‘Is six okay?’ And I was, like, ‘Oh, it’s a Zoom, it won’t be anything.’ So I log in expecting it’s all going to be good, and she says, ‘Are you sitting down?.’ You know that sad tone they use? And she says, ‘I’m so, so sorry but your test results have indicated high-grade cancer cells.’” What did you say? “I replied, ‘That’s unfortunate. 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 considered the operation scary and bizarre. “I fear going under. They walk you down. During crises you are wheeled, but this time I just strolled down with a medical attire and my rear exposed. It felt surreal.” But, she adds, she’s been blessed. No chemotherapy or radiation, just the op. “It’s terrible, but you know what? Thank fuck I found it early. The surgery happened recently and my one side now appears as a grapefruit under a tight bedsheet.” A further beam. “At least the nipple remains.”

The next operation is for health and appearance. Her breasts, she observes, are now “uneven. They didn’t do an implant as small as my original. That’s impolite! I reflected, don’t add insult to injury, I’m already having a difficult experience. How offensive! It’s funny because I said I’d never get my boobs done because I’ve got OCD, and I know they’d never be ideal. Cancer ruined that plan.”

Past Medical Issues

The singer is familiar with health problems. She thinks her attitude toward illness has been so upbeat because she’s experienced in medical emergencies. They have often coincided with peak moments, acting as a reminder, or blow, to make her recall not to take anything for granted. “Honestly, I feel fate says, ‘Enjoying yourself? Sit down.’ Ever since I was a child, it has often paired with achievements for me; something severe or obscure has impacted my body.”

She reminisces to her 11-year-old self, already starting her career starring in the West End in a musical (she was chosen at the age of 9). That’s when she was diagnosed with the heart condition Wolff-Parkinson-White syndrome, which can cause a tachycardia as well as vertigo and heart flutters. “I rehearsed between visits on an intravenous line, and being readmitted at night.” She fast-forwards half a dozen years, and 17-year-old Jess has become part of the girl group Soul Deep while studying at 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 collision and my voice box shifted and I couldn’t sing for a twelve months.”

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