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

You wouldn’t believe it, Jessie J says. There she was preparing for her new album launch in eight years, ecstatically in love with her newish partner, and finally the parent to a young child after facing fertility challenges for ten years, feeling invincible. Then in March she was diagnosed with breast cancer.

The singer-songwriter, birth name Jess Cornish, is famous for being brutally honest. The LP, her latest release, was supposed to be an transparent story, tackling every moment of pain she’d experienced since she last recorded music (endometriosis, miscarriage, failed relationships, psychological manipulation, suicidal thoughts) with characteristic openness. The first single, No Secrets, was released in April. But by then there existed a huge secret. Her diagnosis. Later next release, the upbeat Living My Best Life, debuted in late spring and Cornish was talking to press about how she was enjoying life to the fullest, while all the while living with her cancer. Four weeks after she shared the news, and in July she had a mastectomy.

She shoots me her best “Are you kidding?” glance. “I come out with a song called the track No Secrets. I’m conducting every interview, and they inquire, ‘What’s happening?’ and I answer, ‘Uh, nothing really’” she has just had to call off performances because she’s yet to undergo cosmetic procedures.

We’re at a photography studio in the capital. She is dressed in a light brown synthetic jacket, jeans with detailed white appliqués, cream boots and large glasses. Think motorcycle style meets 1970s Nana Mouskouri. “It seems like I’m in the seventies and I should have a man with facial hair.” Easy Rider, I say, referencing the film. “They used to call me that!” She beams. Cornish is sharp-witted, bold and filter-free. She says she has always wanted to try comedy and is planning to attempt 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 slot at the ceremony when she found a lump. “I quickly sought to get it examined, had an scan, and they were, like, ‘It appears fine; you’ve got really good dense breast tissue.’ And I was, like, ‘Yet I sense it. I’ve got an achy arm and numbness in my fingers whenever I wake up.’ And they replied, ‘How about a biopsy?’ The date was March 28, the following my birthday.” It was a weekend eve. The physician told her if it was bad news she’d reach out on the Monday. By then Cornish had assured herself it was okay. The way she describes it, it was inopportune to face illness when she had a busy schedule.

“We’re two weeks away from launching this thing after a long hiatus and no new music. And she contacted me and said, ‘Can you talk at six?’ And I was, like, ‘It’s virtual, probably routine.’ So I join the call believing it’s all going to be good, and she says, ‘Are you sitting down?.’ You know that sad tone they use? And she says, ‘Unfortunately but your reports have indicated high-grade cancer cells.’” What did you say? “I replied, ‘Well, that’s not great. The timing is terrible.’ My initial thought was, ‘My child depends on me.’”

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 lead you. During crises you are wheeled, but now I just strolled down with a gown on and my rear exposed. It felt surreal.” But, she notes, she’s been lucky. Without chemo or radio, just the surgery. “Cancer sucks, man, but yet Luckily it was detected early. I had the mastectomy four months ago and my affected breast now resembles a grapefruit under a tight bedsheet.” She smiles again. “I got to keep the nipple, though.”

The subsequent surgery is both medical and cosmetic. Her boobs, she observes, are now “asymmetrical. The size doesn’t match. So inconsiderate! I thought, don’t add insult to injury, I’m already having a rough time. Such disrespect! Amusingly I said I’d avoid breast surgery because I’ve got OCD, and I know they’d never be flawless. My plans were disrupted.”

Past Medical Issues

She is familiar with health problems. She believes her outlook on her diagnosis has been so positive because she’s used to physical challenges. Frequently they align with peak moments, serving as a tap on the shoulder, or shock, to highlight not to take anything for granted. “Frankly, I feel life goes, ‘Things going well? Sit down.’ From a young age, it has often paired with high points for me; something severe or obscure has happened to my health.”

She recalls to her 11-year-old self, already beginning starring in the London theater in Whistle Down the Wind (she was chosen at the age of nine). That’s when she was told about the cardiac issue a syndrome, which can cause a fast heartbeat as well as vertigo and irregular beats. “I rehearsed between visits on an IV drip, and going back into hospital at night.” She fast-forwards several years, and 17-year-old Jess has become part of the girl group the group while enrolled in the academy. “I secured a deal, and I had a stroke. Then when I was about to put out music in the year 2020 I had a car crash and my throat was injured and I couldn’t sing for a year.”

Oi, I say, hold on, I can’t keep up. You really had a stroke at 17? She nods|agrees
