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

You wouldn’t believe it, the singer states. There she was preparing for her first album release in nearly a decade, deeply enamored with her current love, and at long last the mother of a toddler after facing fertility challenges for a decade, feeling invincible. Then in spring she was diagnosed with cancer in her breast.

The artist, real name J. Cornish, is known for speaking her mind. The LP, Don’t Tease Me With a Good Time, was supposed to be an open book, addressing every moment of pain she’d endured since she last worked on songs (endometriosis, losing a baby, failed relationships, gaslighting, mental health struggles) with characteristic openness. The initial release, her single No Secrets, was dropped in the spring. But by then there existed a huge secret. The illness. Later follow-up track, her song Living My Best Life, came out in late spring and the artist was speaking publicly about how she was enjoying life to the fullest, while at the same time coping with her cancer. Subsequently she disclosed her condition, and in July she received surgical treatment.

She gives me her best “Seriously?” look. “I come out with a song called No Secrets. I’m giving every press talk, and they inquire, ‘So what’s new with you?’ and I’m, like, ‘Uh, nothing really’” Cornish has just had to cancel tour dates because she’s awaiting reconstructive surgery.

We’re at a photography studio in London. She is dressed in a beige fake-leather jacket, blue jeans with detailed white appliqués, cream boots and big frames. Think motorcycle style meets 1970s Nana Mouskouri. “It seems like I’m in the seventies and I should have a man with facial hair.” Like the film, I say, recalling the film. “They used to call me that!” She grins. Jessie is fast-thinking, irreverent and blunt. She says she has always been interested in humor and is hoping to make her standup debut soon. “I like entertaining. On stage I basically roast the audience.”

Health Struggles and Diagnosis

The artist was planning an slot at the Baftas when she found a lump. “I immediately went to get it examined, had an scan, and they said, ‘It appears fine; your breasts are normal.’ And I insisted, ‘However, it’s there. My arm hurts and numbness in my fingers whenever I rise.’ And they replied, ‘How about a biopsy?’ The date was March 28, the post-birthday.” It was a Friday. The doctor told her if it was bad news she’d contact on the start of the week. By then the singer had assured herself it was okay. The way she tells it, it was inopportune to get cancer when she had a busy schedule.

“We’re two weeks away from launching this thing after eight years without an album and four years without a single. And she [the doctor] texted and said, ‘Can you talk at six?’ And I assumed, ‘A video call, likely minor.’ So I log in believing it’s all going to be positive, and she goes, ‘You might want to sit.’ That sympathetic voice? And she continues, ‘Unfortunately but your test results have come back as high-grade cancer cells.’” What did you say? “I answered, ‘Oh, that’s not ideal, is it?. What awful timing.’ Immediately I felt was, ‘I can’t die because my son needs 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 hate being put under. They walk you down. In urgent cases you go on a gurney, but then I just walked with a gown on and my backside 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 surgery. “It’s terrible, but however Thank fuck I found it early. I had the mastectomy recently and my affected breast now looks like a fruit under fabric.” She smiles again. “The nipple was preserved.”

The follow-up procedure is both medical and cosmetic. Her breasts, she remarks, are now “uneven. The size doesn’t match. That’s impolite! I thought, no need to bully me, I’m already having a rough time. Such disrespect! It’s funny because I said I’d avoid breast surgery because I’ve got perfectionism, and I know they’d never be flawless. My plans were disrupted.”

A History of Health Challenges

The singer is familiar with health problems. She thinks her attitude toward illness has been so upbeat because she’s experienced in physical challenges. Frequently they align with career highs, functioning as a wake-up call, or punch in the stomach, to make her recall not to be complacent. “Frankly, I feel fate says, ‘Things going well? Sit down.’ Ever since I was a child, it has consistently accompanied moments of success for me; a major or strange event has affected my well-being.”

She recalls to her childhood, already starting her career featuring in the West End in the production (she was selected at the age of nine). That’s when she was told about the medical problem WPW, which can cause a tachycardia as well as lightheadedness and palpitations. “I rehearsed between visits on an IV drip, and returning to the hospital at night.” She jumps ahead several years, and young Jessica has joined the trio the group while enrolled in the academy. “I signed my initial contract, and I had a cerebral event. Then when I was planning to release songs in recently I had a car crash and my voice box shifted and I lost my voice for a year.”

Wow, I say, slow down, I need a moment. At just 17? She nods|agrees
