‘It has pushed me to live more fully’: Jessie J on her health battle, comebacks and cracking China

You can’t imagine it, Jessie J says. At that moment readying for her comeback record in eight years, blissfully happy with her recent boyfriend, and at long last the mom to a little one after facing fertility challenges for a decade, on top of the world. Then in March she was diagnosed with cancer in her breast.

The singer-songwriter, actual name Jess Cornish, is famous for speaking her mind. The record, the provocatively titled album, was supposed to be an candid account, dealing with every moment of pain she’d faced since she last made an album (a gynecological condition, losing a baby, failed relationships, emotional abuse, suicidal thoughts) with her usual frankness. The lead track, No Secrets, was dropped in April. But by then there was a mighty secret. The cancer. Later next release, Living My Best Life, debuted in May and she was talking to press about how she was living her best life, while all the while coping with her cancer. Four weeks after she went public, and in the start of summer she received surgical treatment.

She offers me her best “Seriously?” glance. “I come out with a song called No Secrets. I’m doing every interview, and they inquire, ‘What’s happening?’ and I’m, like, ‘Uh, nothing really’” Cornish has just had to call off performances because she’s awaiting follow-up surgery.

Our interview takes place at a studio in London. She is dressed in a beige fake-leather jacket, jeans with ornate white designs, off-white boots and large glasses. Picture biker chic meets 70s singer aesthetic. “It seems like I’m in the 1970s and I should have a boyfriend with a big tache.” Like the film, I say, recalling the film. “They used to call me that!” She smiles. She is quick, bold and direct. She says she has always wanted to try comedy and is planning to attempt her standup debut next year. “I like entertaining. During performances I frequently joke about the audience.”

Personal Battles and News

The artist was getting ready for an appearance at the Baftas when she noticed an abnormality. “I immediately went to get it checked, had an scan, and they told me, ‘It seems benign; your tissue is healthy.’ And I insisted, ‘But I can feel it. I’ve got an achy arm and pins and needles in my hands whenever I get up.’ And they replied, ‘How about a biopsy?’ The date was March 28, the day after my birthday.” It was a Friday. The specialist told her if it was concerning she’d contact on the start of the week. By then Cornish had convinced herself it was fine. The way she explains it, it was just bad timing to face illness when she had so much on.

“It was a fortnight prior from launching this thing after a long hiatus and no new music. And the doctor messaged and said, ‘Can you talk at six?’ And I was, like, ‘A video call, likely minor.’ So I log in believing it’s all going to be fine, and she says, ‘Are you sitting down?.’ That sympathetic voice? And she reveals, ‘I’m so, so sorry but your reports have come back as high-grade cancer cells.’” What was your reaction? “I answered, ‘That’s unfortunate. That’s not fucking great timing.’ My initial thought was, ‘My child depends on me.’”

I’ve been labeled difficult for knowing myself

She found the surgery terrifying and absurd. “I hate being put under. You’re escorted. You know when you have emergency surgery you go on a gurney, but then I just strolled down with a gown on and my rear exposed. It felt surreal.” But, she notes, she’s been fortunate. No chemotherapy or radiation, just the procedure. “Cancer sucks, man, but you know what? Thank fuck I found it early. The surgery happened four months ago and my right breast now resembles a odd shape.” Another grin. “The nipple was preserved.”

The subsequent surgery is both medical and cosmetic. Her breasts, she notes, are now “uneven. The size doesn’t match. How rude! I reflected, no need to bully me, I’m already having a rough time. 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 flawless. Illness changed that.”

A History of Health Challenges

Cornish is familiar with health problems. She believes her outlook on her diagnosis has been so positive because she’s experienced in health crises. Many times they occur alongside peak moments, acting as a reminder, or blow, to remind her not to take anything for granted. “Frankly, I feel fate says, ‘Things going well? Hold on.’ From a young age, it has consistently accompanied high points for me; a major or strange event has affected my well-being.”

She recalls to her childhood, already starting her career performing in the London theater in the production (she was chosen at the age of 9). That’s when she was found to have the heart condition a syndrome, which can cause a fast heartbeat as well as lightheadedness and irregular beats. “I attended rehearsals intermittently on an intravenous line, and being readmitted at night.” She fast-forwards several years, and 17-year-old Jess has entered the girl group Soul Deep while attending the academy. “I secured a deal, and I had a brain incident. Then when I was about to put out music in 2020 I had a automobile accident and my larynx moved up and I lost my voice for a long period.”

Wow, I say, hold on, I need a moment. A stroke so young? She nods|agrees
