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

You can’t imagine it, the singer says. At that moment preparing for her first album release in nearly a decade, deeply enamored with her newish partner, and at long last the mom to a little one after struggling to conceive for ten years, on top of the world. Then in March she was told she had cancer in her breast.

The musician, actual name Jess Cornish, is known for being brutally honest. The album, her latest release, was intended as an transparent story, addressing every ounce of devastation she’d endured since she last recorded music (a gynecological condition, miscarriage, unsuccessful partnerships, psychological manipulation, mental health struggles) with typical candour. The first single, No Secrets, was released in April. But by then there was a mighty secret. The illness. Later next release, the upbeat Living My Best Life, was released in May and she was speaking publicly about how she was thriving, while all the while living with breast cancer. Four weeks after she shared the news, and in July she had a mastectomy.

She gives me her best “Are you kidding?” look. “I put out with a song called the track No Secrets. I’m doing every media appearance, and they’re, like, ‘What’s happening?’ and I respond, ‘Well, not much…’” she has just had to cancel tour dates because she’s awaiting reconstructive surgery.

We’re at a studio in London. She is sporting a beige fake-leather jacket, jeans with ornate white designs, off-white boots and large glasses. Picture motorcycle style 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 film. “I was nicknamed that in school!” She beams. Jessie is sharp-witted, irreverent and filter-free. She says she has always been interested in humor and is planning to attempt her standup debut in the coming year. “I like entertaining. When performing I frequently joke about the fans.”

Health Struggles and Diagnosis

Cornish was preparing for an slot at the ceremony when she discovered a mass. “I quickly sought to get it looked at, had an test, and they said, ‘It seems benign; your breasts are normal.’ And I was, like, ‘Yet I sense it. I’ve got an achy arm and pins and needles in my hands whenever I get up.’ And they said, ‘How about a biopsy?’ The date was March 28, the post-birthday.” It was a weekend eve. The specialist told her if it was serious she’d reach out on the start of the week. By then the singer had convinced herself it was nothing. The way she describes it, it was inopportune to get cancer when she had a busy schedule.

“It was a fortnight prior from launching this thing after eight years without an album and no new music. And she [the doctor] texted and said, ‘Can you talk at six?’ And I was, like, ‘Oh, it’s a Zoom, it won’t be anything.’ So I jump on the Zoom thinking it’s all going to be good, and she says, ‘You might want to sit.’ That sympathetic voice? And she continues, ‘I’m so, so sorry but your reports have come back as aggressive cancer.’” What did you say? “I said, ‘Well, that’s not great. That’s not fucking great timing.’ My initial thought was, ‘I can’t die because my son needs me.’”

Some men find me challenging due to my self-awareness

She found the surgery frightening and surreal. “I hate being put under. They lead you. During crises you roll down in a bed, but then I just marched with a hospital gown and my bum hanging out. It felt surreal.” But, she notes, she’s been lucky. No chemotherapy or radiation, just the op. “It’s terrible, but however I’m grateful it was caught soon. I underwent removal recently and my one side now resembles a grapefruit under a tight bedsheet.” A further beam. “I got to keep the nipple, though.”

The next operation is therapeutic and aesthetic. Her breasts, she notes, are now “different sizes. They didn’t do an implant as small as my original. How rude! I thought, don’t add insult to injury, I’m already having a rough time. Such disrespect! It’s funny because I said I’d not undergo augmentation because I’ve got perfectionism, and I know they’d never be flawless. Illness changed that.”

Previous Struggles

She is no stranger to illness. She believes her outlook on her diagnosis has been so positive because she’s used to medical emergencies. Frequently they align with professional successes, serving as a tap on the shoulder, or blow, to remind her not to take anything for granted. “Truly, I feel life goes, ‘You having a good time? Sit down.’ Ever since I was a child, it has often paired with achievements for me; a major or strange event has happened to my health.”

She recalls to her childhood, already starting her career featuring in the West End in a musical (she was selected at the age of nine years old). That’s when she was told about the heart condition a syndrome, which can cause a tachycardia as well as dizziness and palpitations. “I was going in and out of rehearsals on an drip, and being readmitted at night.” She jumps ahead six years, and 17-year-old Jess has entered the trio Soul Deep while enrolled in the Brit School. “I secured a deal, and I had a cerebral event. Then when I was ready to debut in the year 2020 I had a automobile accident and my voice box shifted and I was unable to vocalize for a twelve months.”

Hey, I say, slow down, I am overwhelmed. You really had a stroke at 17? She nods|agrees
