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

You can’t imagine it, Jessie J remarks. There she was readying for her comeback record in nearly a decade, ecstatically in love with her newish partner, and at long last the parent to a young child after dealing with conception issues for ten years, on top of the world. Then in spring she was told she had a breast cancer diagnosis.

The musician, birth name Jess Cornish, is famous for being brutally honest. The LP, her latest release, was intended as an transparent story, dealing with every moment of pain she’d endured since she last recorded music (endometriosis, miscarriage, failed relationships, gaslighting, suicide) with her usual frankness. The lead track, No Secrets, was launched in the spring. But by then there remained a major undisclosed truth. The cancer. Then second single, her song Living My Best Life, came out in May and she was speaking publicly about how she was living her best life, while at the same time dealing with breast cancer. Four weeks after she shared the news, and in the start of summer she had a mastectomy.

She shoots me her best “Are you kidding?” glance. “I release with a song called No Secrets. I’m conducting every press talk, and they inquire, ‘So what’s new with you?’ and I answer, ‘Well, not much…’” she has just had to call off performances because she’s yet to undergo cosmetic procedures.

We meet at a photo studio in London. She is wearing a light brown synthetic jacket, denim trousers with ornate white designs, beige footwear and large glasses. Think rocker vibe meets vintage look. “I feel like I’m in the 1970s and I should have a man with facial hair.” Easy Rider, I say, thinking of the movie. “I was nicknamed that in school!” She beams. Cornish is quick, irreverent and direct. She says she has always been interested in humor and is hoping to make her standup debut next year. “I love making people laugh. When performing I basically roast the fans.”

Health Struggles and Diagnosis

The artist was preparing for an appearance at the awards show when she noticed an abnormality. “I quickly sought to get it looked at, had an test, and they were, like, ‘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 rise.’ And they suggested, ‘How about a biopsy?’ That was 28 March, the day after my birthday.” It was a weekend eve. The doctor told her if it was bad news she’d call on the Monday. By then she had convinced herself it was nothing. The way she tells it, it was just bad timing to get cancer when she had many commitments.

“It was a fortnight prior from releasing the album after years away and an extended break. And she contacted me and said, ‘Are you free at six?’ And I thought, ‘Oh, it’s a Zoom, it won’t be anything.’ So I join the call expecting it’s all going to be positive, and she says, ‘Please take a seat.’ You know that sad tone they use? And she reveals, ‘I’m so, so sorry but your reports have shown aggressive cancer.’” What did you say? “I said, ‘Well, that’s not great. That’s not fucking great timing.’ Immediately I felt was, ‘I can’t die because my son needs me.’”

Some men find me challenging due to my self-awareness

She considered the operation frightening and surreal. “I hate being put under. They lead you. During crises you are wheeled, but then I just walked with a medical attire and my backside out. Like a dystopian scene.” But, Cornish says, she’s been fortunate. Without chemo or radio, just the op. “It’s terrible, but however Luckily it was detected early. The surgery happened a few months back and my affected breast now resembles a odd shape.” She smiles again. “I got to keep the nipple, though.”

The subsequent surgery is for health and appearance. Her boobs, she remarks, are now “uneven. They didn’t do an implant as small as my original. So inconsiderate! I thought, why make it worse, I’m already having a rough time. How offensive! Amusingly I said I’d not undergo augmentation because I’ve got OCD, and I know they’d never be perfect. Cancer ruined that plan.”

Past Medical Issues

Cornish is familiar with health problems. She feels her outlook on her diagnosis has been so optimistic because she’s used to medical emergencies. Many times they occur alongside peak moments, acting as a reminder, or punch in the stomach, to remind her not to assume everything is fine. “Frankly, I feel fate says, ‘Things going well? Hold on.’ Since childhood, it has often paired with achievements for me; a serious or unusual issue has impacted my body.”

She reminisces to her 11-year-old self, already making her debut featuring in the stage in a musical (she was cast at the age of 9). That’s when she was told about the cardiac issue Wolff-Parkinson-White syndrome, which can cause a rapid pulse as well as lightheadedness and irregular beats. “I was going in and out of rehearsals on an IV drip, and going back into hospital at night.” She fast-forwards half a dozen years, and teenage Jess has become part of the trio the group while studying at the Brit School. “I just got my first record deal, and I had a brain incident. Then when I was ready to debut in 2020 I had a collision and my larynx moved up and I was unable to vocalize for a twelve months.”

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