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

You can’t imagine it, the singer states. At that moment gearing up for her new album launch in nearly a decade, blissfully happy with her current love, and finally the parent to a young child after facing fertility challenges for a decade, riding high. Suddenly in spring she was diagnosed with cancer in her breast.

The singer-songwriter, real name J. Cornish, is renowned for being brutally honest. The LP, her latest release, was intended as an candid account, addressing every ounce of devastation she’d faced since she last made an album (endometrial issues, miscarriage, failed relationships, gaslighting, suicide) with characteristic openness. The lead track, No Secrets, was launched in April. But by then there existed a huge secret. The cancer. Then second single, her song Living My Best Life, came out in May and Cornish was giving interviews about how she was enjoying life to the fullest, while at the same time dealing with breast cancer. Subsequently she shared the news, and in early July she received surgical treatment.

She shoots me her best “Are you kidding?” glance. “I put out with a song called No Secrets. I’m doing every press talk, and they inquire, ‘What’s happening?’ and I answer, ‘Erm, yeah, nothing …’” the singer has just had to cancel tour dates because she’s yet to undergo follow-up surgery.

We’re at a photo studio in London. She is dressed in a beige fake-leather jacket, jeans with elaborate white patches, off-white boots and big frames. Imagine biker chic meets vintage look. “I feel like I’m in the seventies and I should have a boyfriend with a big tache.” Easy Rider, I say, recalling the film. “They used to call me that!” She grins. Cornish is sharp-witted, unfiltered and blunt. She says she has always wanted to try comedy and is planning to attempt her initial standup show soon. “I like entertaining. During performances I basically roast the crowd.”

Personal Battles and News

Cornish was preparing for an appearance at the ceremony when she noticed an abnormality. “I quickly sought to get it checked, had an ultrasound, and they were, like, ‘It appears fine; you’ve got really good dense breast tissue.’ And I insisted, ‘However, it’s there. I’ve got an achy arm and pins and needles in my hands whenever I rise.’ And they said, ‘Well, let’s just do a biopsy?’ It happened on March 28, the following my birthday.” It was a weekend eve. The specialist told her if it was serious she’d reach out on the Monday. By then the singer had persuaded herself it was fine. The way she tells it, it was simply too inconvenient to get cancer when she had many commitments.

“Just two weeks before from launching this thing after a long hiatus and an extended break. And she contacted me and said, ‘Are you free 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 positive, and she goes, ‘Please take a seat.’ You know that sad tone they use? And she says, ‘I regret to inform you but your test results have shown aggressive cancer.’” What did you say? “I answered, ‘Oh, that’s not ideal, is it?. That’s not fucking great timing.’ The first thing I thought was, ‘I can’t die because my son needs me.’”

I’ve been labeled difficult for knowing myself

She considered the operation terrifying and absurd. “I dislike anesthesia. They lead you. During crises you are wheeled, but this time I just marched with a gown on and my bum hanging out. You feel like you’re in an episode of Black Mirror.” But, Cornish says, she’s been lucky. No chemo, no radiotherapy, just the procedure. “It’s terrible, but however Thank fuck I found it early. I had the mastectomy recently and my one side now looks like a odd shape.” Another grin. “The nipple was preserved.”

The follow-up procedure is both medical and cosmetic. Her breasts, she notes, are now “different sizes. The size doesn’t match. How rude! I felt, why make it worse, I’m already having a rough time. How offensive! Amusingly I said I’d avoid breast surgery because I’ve got obsessive tendencies, and I know they’d never be ideal. Cancer ruined that plan.”

A History of Health Challenges

The singer is no stranger to illness. She feels her attitude toward illness has been so upbeat because she’s experienced in medical emergencies. Many times they occur alongside peak moments, serving as a tap on the shoulder, or punch in the stomach, to make her recall not to take anything for granted. “Honestly, I feel the universe whispers, ‘Enjoying yourself? Hold on.’ Ever since I was a child, it has consistently accompanied high points for me; a serious or unusual issue has affected my well-being.”

She takes me back to her youth, already beginning featuring in the stage in a musical (she was chosen at the age of nine years old). That’s when she was found to have the heart condition WPW, which can cause a fast heartbeat as well as lightheadedness and irregular beats. “I attended rehearsals intermittently on an IV drip, and going back into hospital at night.” She jumps ahead six years, and teenage Jess has joined the trio the group while enrolled in the Brit School. “I secured a deal, 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 couldn’t sing for a year.”

Hey, I say, wait, I need a moment. You really had a stroke at 17? She nods|agrees
