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

You couldn’t make it up, Jessie J remarks. At that moment readying for her new album launch in nearly a decade, ecstatically in love with her current love, and at long last the mother of a toddler after dealing with conception issues for ten years, riding high. Then in March she was told she had a breast cancer diagnosis.

The musician, actual name Jessica Cornish, is famous for telling it as it is. The album, Don’t Tease Me With a Good Time, was supposed to be an transparent story, dealing with every moment of pain she’d faced since she last worked on songs (endometriosis, miscarriage, failed relationships, emotional abuse, suicidal thoughts) with her usual frankness. The first single, the song No Secrets, was released in April. But by then there existed a huge secret. Her diagnosis. Later follow-up track, the upbeat Living My Best Life, was released in May and the artist was talking to press about how she was enjoying life to the fullest, while at the same time dealing with the disease. Subsequently she shared the news, and in early July she underwent breast removal surgery.

She offers me her best “Are you kidding?” look. “I put out with a song called No Secrets. I’m conducting every press talk, and they’re, like, ‘What’s happening?’ and I’m, like, ‘Well, not much…’” the singer has just had to cancel tour dates because she’s yet to undergo reconstructive surgery.

Our interview takes place at a photo studio in London. She is wearing a beige fake-leather jacket, jeans with detailed white appliqués, beige footwear and oversized specs. Imagine rocker vibe meets 70s singer aesthetic. “As if I’m in the 1970s and I should have a partner with a mustache.” Easy Rider, I say, thinking of the movie. “I was nicknamed that in school!” She smiles. She is fast-thinking, irreverent and filter-free. She says she has always wanted to try comedy and is planning to attempt her standup debut in the coming year. “I enjoy humor. On stage I frequently joke about the crowd.”

Medical Challenges and Discovery

Cornish was preparing for an appearance at the Baftas when she discovered a mass. “I immediately went to get it looked at, had an scan, and they were, like, ‘It looks like nothing; your tissue is healthy.’ And I was, like, ‘Yet I sense it. I have arm pain and numbness in my fingers whenever I wake up.’ And they replied, ‘Well, let’s just do a biopsy?’ It happened on March 28, the following my birthday.” It was a weekend eve. The specialist told her if it was serious she’d call on the Monday. By then Cornish had persuaded herself it was fine. The way she tells it, it was simply too inconvenient to receive a diagnosis when she had a busy schedule.

“We’re two weeks away from launching this thing after years away and four years without a single. And she contacted me and said, ‘Is six okay?’ And I assumed, ‘It’s virtual, probably routine.’ So I jump on the Zoom believing it’s all going to be fine, and she informs me, ‘Are you sitting down?.’ The solemn tone? And she says, ‘I’m so, so sorry but your biopsy results have shown malignant cells.’” What did you say? “I answered, ‘Oh, that’s not ideal, is it?. That’s not fucking great timing.’ The first thing I thought was, ‘My child depends on me.’”

Men have called me difficult because I’m a strong person who understands who I am

She viewed the procedure scary and bizarre. “I hate being put under. They lead you. In urgent cases you are wheeled, but now I just walked with a gown on and my bum hanging out. It felt surreal.” But, she adds, she’s been lucky. No chemotherapy or radiation, just the procedure. “Cancer sucks, man, but however Thank fuck I found it early. I had the mastectomy four months ago and my one side now looks like a odd shape.” Another grin. “I got to keep the nipple, though.”

The follow-up procedure is both medical and cosmetic. Her boobs, she observes, are now “asymmetrical. The implant is larger than before. That’s impolite! I felt, no need to bully me, I’m already having a rough time. How offensive! Amusingly I said I’d not undergo augmentation because I’ve got obsessive tendencies, and I know they’d never be perfect. Cancer ruined that plan.”

A History of Health Challenges

The singer is familiar with health problems. She feels her perspective on the cancer has been so optimistic because she’s experienced in medical emergencies. Many times they occur alongside career highs, functioning as a wake-up call, or blow, to remind her not to assume everything is fine. “Truly, I feel the universe whispers, ‘You having a good time? Hold on.’ Ever since I was a child, it has often paired with achievements for me; something severe or obscure has affected my well-being.”

She reminisces to her childhood, already making her debut performing in the London theater in a musical (she was cast at the age of nine years old). That’s when she was told about the medical problem a syndrome, which can cause a fast heartbeat as well as vertigo and palpitations. “I attended rehearsals intermittently on an intravenous line, and returning to the hospital at night.” She jumps ahead six years, and young Jessica has joined the female band Soul Deep while studying at the performing arts school. “I secured a deal, and I had a cerebral event. Then when I was planning to release songs in the year 2020 I had a collision and my larynx moved up and I was unable to vocalize for a long period.”

Oi, I say, hold on, I am overwhelmed. A stroke so young? She nods|agrees
