‘It has taught me to embrace life more’: Jessica Cornish on her health battle, comebacks and cracking China

You wouldn’t believe it, Jessie J says. There she was readying for her comeback record in eight years, deeply enamored with her current love, and at long last the mother of a toddler after dealing with conception issues for a decade, feeling invincible. Suddenly in spring she was told she had cancer in her breast.

The singer-songwriter, birth name J. Cornish, is famous for being brutally honest. The LP, Don’t Tease Me With a Good Time, was meant as an transparent story, tackling every ounce of devastation she’d faced since she last made an album (a gynecological condition, pregnancy loss, failed relationships, gaslighting, suicide) with her usual frankness. The first single, the song No Secrets, was dropped in the spring. But by then there remained a major undisclosed truth. Her diagnosis. Later follow-up track, Living My Best Life, debuted in late spring and the artist was giving interviews about how she was thriving, while at the same time living with her cancer. A month later she shared the news, and in early July she received surgical treatment.

She shoots me her best “What the fuck?” look. “I come out with a song called No Secrets. I’m giving every interview, and they ask, ‘So what’s new with you?’ and I answer, ‘Well, not much…’” the singer has just had to call off performances because she’s still waiting for reconstructive surgery.

Our interview takes place at a studio in the capital. She is dressed in a beige fake-leather jacket, denim trousers with elaborate white patches, cream boots and large glasses. Imagine rocker vibe meets 1970s Nana Mouskouri. “It seems like I’m in the 1970s and I should have a boyfriend with a big tache.” Easy Rider, I say, thinking of the movie. “They used to call me that!” She beams. Cornish is sharp-witted, irreverent and direct. She says she has always been interested in humor and is hoping to make her standup debut soon. “I love making people laugh. On stage I frequently joke about the fans.”

Medical Challenges and Discovery

She was getting ready for an performance at the Baftas when she found a lump. “I immediately went to get it checked, had an ultrasound, and they told me, ‘It seems benign; your breasts are normal.’ And I responded, ‘Yet I sense it. I’ve got an achy arm and pins and needles in my hands whenever I get up.’ And they suggested, ‘How about a biopsy?’ That was 28 March, the following my birthday.” It was a weekend eve. The physician told her if it was serious she’d reach out on the Monday. By then Cornish had assured herself it was fine. The way she tells it, it was simply too inconvenient to receive a diagnosis when she had so much on.

“It was a fortnight prior from releasing the album after eight years without an album and no new music. And she contacted me and said, ‘Are you free at six?’ And I was, like, ‘It’s virtual, probably routine.’ So I log in believing it’s all going to be fine, and she says, ‘Please take a seat.’ The solemn tone? And she continues, ‘I regret to inform you but your biopsy results have indicated high-grade cancer cells.’” What did you say? “I answered, ‘Oh, that’s not ideal, is it?. What awful timing.’ The first thing I thought was, ‘I have to survive for my boy.’”

I’ve been labeled difficult for knowing myself

She viewed the procedure frightening and surreal. “I hate being put under. You’re escorted. You know when you have emergency surgery you roll down in a bed, but this time I just walked with a medical attire and my bum hanging out. It felt surreal.” But, she notes, she’s been fortunate. No chemo, no radiotherapy, just the surgery. “Cancer is awful, but however I’m grateful it was caught soon. I had the mastectomy four months ago and my one side now resembles a fruit under fabric.” Another grin. “The nipple was preserved.”

The subsequent surgery is both medical and cosmetic. Her chest, she remarks, are now “asymmetrical. The implant is larger than before. That’s impolite! I thought, why make it worse, I’m already having a difficult experience. So rude! Amusingly I said I’d avoid breast surgery because I’ve got perfectionism, and I know they’d never be ideal. Illness changed that.”

Past Medical Issues

The singer is familiar with health problems. She feels her perspective on the cancer has been so positive because she’s familiar with physical challenges. Frequently they align with career highs, functioning as a wake-up call, or blow, to make her recall not to assume everything is fine. “Honestly, I feel fate says, ‘You having a good time? Hold on.’ Since childhood, it has often paired with high points for me; something severe or obscure has affected my well-being.”

She takes me back to her childhood, already beginning performing in the London theater in a musical (she was chosen at the age of 9). That’s when she was diagnosed with the heart condition a syndrome, which can cause a fast heartbeat as well as vertigo and heart flutters. “I attended rehearsals intermittently on an drip, and being readmitted at night.” She fast-forwards several years, and young Jessica has become part of the trio the group while studying at the performing arts school. “I secured a deal, and I had a brain incident. Then when I was ready to debut in the year 2020 I had a car crash and my voice box shifted and I lost my voice for a year.”

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