‘It has taught me to embrace life more’: Jessie J on cancer, comebacks and conquering the Chinese market

You couldn’t make it up, Jessie J says. At that moment readying for her comeback record in nearly a decade, ecstatically in love with her current love, and finally the parent to a young child after struggling to conceive for a decade, on top of the world. Then in spring she was found to have cancer in her breast.

The singer-songwriter, actual name Jess Cornish, is famous for telling it as it is. The record, Don’t Tease Me With a Good Time, was intended as an candid account, tackling every ounce of devastation she’d experienced since she last recorded music (endometriosis, pregnancy loss, unsuccessful partnerships, emotional abuse, suicide) with characteristic openness. The initial release, the song No Secrets, was released in the spring. But by then there was a mighty secret. The illness. Later follow-up track, the upbeat Living My Best Life, came out in May and she was speaking publicly about how she was enjoying life to the fullest, while all the while coping with her cancer. A month later she disclosed her condition, and in the start of summer she had a mastectomy.

She offers me her best “Are you kidding?” look. “I come out with a song called No Secrets. I’m doing every media appearance, and they ask, ‘Any updates?’ and I respond, ‘Well, not much…’” she has just had to call off performances because she’s still waiting for cosmetic procedures.

We’re at a photo studio in London. She is dressed in a beige fake-leather jacket, jeans with detailed white appliqués, beige footwear and big frames. Picture rocker vibe meets 70s singer aesthetic. “It seems like I’m in the 70s and I should have a man with facial hair.” Like the film, I say, recalling the picture. “I was nicknamed that in school!” She grins. Cornish is sharp-witted, irreverent and blunt. She says she has always been interested in humor and is aiming for her first comedy performance in the coming year. “I love making people laugh. During performances I frequently joke about the crowd.”

Personal Battles and News

The artist was preparing for an performance at the Baftas when she found a lump. “I quickly sought to get it examined, had an scan, and they told me, ‘It looks like nothing; your breasts are normal.’ And I responded, ‘However, it’s there. I’ve got an achy arm and tingling in my hands whenever I rise.’ And they suggested, ‘We should biopsy it?’ The date was March 28, the following my birthday.” It was a Friday. The doctor told her if it was concerning she’d reach out on the Monday. By then the singer had convinced herself it was nothing. The way she describes it, it was simply too inconvenient to receive a diagnosis when she had so much on.

“We’re two weeks away from debuting the project after eight years without an album and no new music. And the doctor messaged and said, ‘Are you free at six?’ And I thought, ‘It’s virtual, probably routine.’ So I log in believing it’s all going to be fine, and she informs me, ‘You might want to sit.’ That sympathetic voice? And she reveals, ‘I regret to inform you but your reports have come back as malignant cells.’” What did you say? “I answered, ‘Well, that’s not great. The timing is terrible.’ The first thing I thought was, ‘I have to survive for my boy.’”

I’ve been labeled difficult for knowing myself

She considered the operation terrifying and absurd. “I fear going under. They lead you. You know when you have emergency surgery you are wheeled, but this time I just marched with a medical attire and my rear exposed. You feel like you’re in an episode of Black Mirror.” But, Cornish says, she’s been blessed. Without chemo or radio, just the op. “It’s terrible, but yet I’m grateful it was caught soon. The surgery happened a few months back and my right breast now appears as a fruit under fabric.” A further beam. “At least the nipple remains.”

The follow-up procedure is for health and appearance. Her breasts, she notes, are now “different sizes. The size doesn’t match. That’s impolite! I thought, no need to bully me, I’m already having a rough time. So rude! Ironically I said I’d avoid breast surgery because I’ve got perfectionism, and I know they’d never be perfect. My plans were disrupted.”

A History of Health Challenges

The singer is familiar with health problems. She thinks her outlook on her diagnosis has been so upbeat because she’s familiar with health crises. Many times they occur alongside career highs, acting as a reminder, or punch in the stomach, to make her recall not to be complacent. “Honestly, I feel fate says, ‘You having a good time? Sit down.’ Ever since I was a child, it has always gone alongside achievements for me; a serious or unusual issue has happened to my health.”

She reminisces to her 11-year-old self, already making her debut featuring in the London theater in Whistle Down the Wind (she was selected at the age of nine). That’s when she was told about the cardiac issue a syndrome, which can cause a fast heartbeat as well as dizziness and heart flutters. “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 female band the group while studying at the academy. “I signed my initial contract, and I had a stroke. Then when I was ready to debut in recently I had a collision and my voice box shifted and I was unable to vocalize for a long period.”

Hey, I say, hold on, I am overwhelmed. At just 17? She nods|agrees
