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

You wouldn’t believe it, the singer says. At that moment gearing up for her comeback record in eight years, blissfully happy with her recent boyfriend, and at long last the parent to a young child after dealing with conception issues for ten years, on top of the world. Suddenly in March she was diagnosed with cancer in her breast.

The artist, birth name J. Cornish, is famous for speaking her mind. The LP, the provocatively titled album, was meant as an candid account, addressing every moment of pain she’d faced since she last recorded music (endometriosis, pregnancy loss, failed relationships, emotional abuse, mental health struggles) with typical candour. The first single, No Secrets, was released in April. But by then there existed a huge secret. The illness. Later next release, the upbeat Living My Best Life, debuted in late spring and the artist was giving interviews about how she was enjoying life to the fullest, while at the same time living with breast cancer. Four weeks after she disclosed her condition, and in early July she received surgical treatment.

She gives me her best “Are you kidding?” glance. “I come out with a song called No Secrets. I’m conducting every media appearance, and they’re, like, ‘So what’s new with you?’ and I respond, ‘Uh, nothing really’” she has just had to call off performances because she’s still waiting for reconstructive surgery.

We’re at a studio in London. She is sporting a light brown synthetic jacket, blue jeans with elaborate white patches, cream boots and big frames. Think motorcycle style meets 1970s Nana Mouskouri. “I feel like I’m in the seventies and I should have a man with facial hair.” Easy Rider, I say, recalling the picture. “They used to call me that!” She beams. Cornish is sharp-witted, bold and blunt. She says she has always been interested in humor and is hoping to make her first comedy performance next year. “I like entertaining. When performing I basically roast the fans.”

Medical Challenges and Discovery

Cornish was planning an slot at the Baftas when she found a lump. “I promptly visited to get it looked at, had an ultrasound, and they told me, ‘It seems benign; your tissue is healthy.’ And I insisted, ‘But I can feel it. My arm hurts and tingling in my hands whenever I rise.’ And they said, ‘We should biopsy it?’ It happened on March 28, the day after my birthday.” It was a Friday. The specialist told her if it was serious she’d contact on the Monday. By then Cornish had persuaded herself it was fine. The way she explains it, it was just bad timing to face illness when she had many commitments.

“Just two weeks before from launching this thing after eight years without an album and four years without a single. And the doctor messaged and said, ‘Is six okay?’ And I assumed, ‘Oh, it’s a Zoom, it won’t be anything.’ So I join the call thinking it’s all going to be fine, and she says, ‘Are you sitting down?.’ That sympathetic voice? And she says, ‘I regret to inform you but your biopsy results have come back as high-grade cancer cells.’” What was your reaction? “I replied, ‘That’s unfortunate. The timing is terrible.’ My initial thought was, ‘I have to survive for my boy.’”

I’ve been labeled difficult for knowing myself

She viewed the procedure terrifying and absurd. “I hate being put under. They walk you down. During crises you go on a gurney, but now I just strolled down with a gown on and my bum hanging out. Like a dystopian scene.” But, Cornish says, she’s been lucky. Without chemo or radio, just the op. “It’s terrible, but you know what? Thank fuck I found it early. I underwent removal a few months back and my affected breast now resembles a fruit under fabric.” Another grin. “At least the nipple remains.”

The follow-up procedure is both medical and cosmetic. Her breasts, she notes, are now “uneven. They didn’t do an implant as small as my original. How rude! I reflected, don’t add insult to injury, I’m already having a difficult experience. So rude! Amusingly I said I’d not undergo augmentation because I’ve got OCD, and I know they’d never be ideal. Cancer ruined that plan.”

Previous Struggles

Cornish is accustomed to medical issues. She thinks her attitude toward illness has been so positive because she’s used to medical emergencies. Many times they occur alongside peak moments, acting as a reminder, or shock, to make her recall not to assume everything is fine. “Frankly, I feel fate says, ‘Enjoying yourself? Sit down.’ Since childhood, it has often paired with moments of success for me; a major or strange event has happened to my health.”

She takes me back to her youth, already making her debut performing in the London theater in a musical (she was cast at the age of nine). That’s when she was found to have the cardiac issue a syndrome, which can cause a tachycardia as well as dizziness and palpitations. “I rehearsed between visits on an intravenous line, and going back into hospital at night.” She jumps ahead half a dozen years, and young Jessica has joined the female band Soul Deep while attending the Brit School. “I just got my first record deal, and I had a brain incident. Then when I was ready to debut in recently I had a collision and my throat was injured and I lost my voice for a twelve months.”

Hey, I say, slow down, I can’t keep up. A stroke so young? She nods|agrees
