‘It has pushed me to live more fully’: Jessica Cornish on cancer, career returns and cracking China

You wouldn’t believe it, Jessie J remarks. At that moment gearing up for her new album launch in eight years, ecstatically in love with her newish partner, and finally the parent to a young child after struggling to conceive for ten years, feeling invincible. Then in March she was told she had cancer in her breast.

The singer-songwriter, actual name Jessica Cornish, is known for speaking her mind. The LP, the provocatively titled album, was meant as an candid account, tackling every moment of pain she’d experienced since she last made an album (endometrial issues, pregnancy loss, failed relationships, emotional abuse, suicide) with typical candour. The first single, the song No Secrets, was dropped in the spring. But by then there existed a huge secret. The cancer. Then second single, her song Living My Best Life, debuted in late spring and she was giving interviews about how she was enjoying life to the fullest, while at the same time living with the disease. Subsequently she shared the news, and in early July she had a mastectomy.

She offers me her best “What the fuck?” expression. “I put out with a song called No Secrets. I’m giving every media appearance, and they’re, like, ‘What’s happening?’ and I respond, ‘Well, not much…’” she has just had to call off performances because she’s still waiting for reconstructive surgery.

We’re at a photography studio in the capital. She is dressed in a beige fake-leather jacket, denim trousers with detailed white appliqués, beige footwear and large glasses. Think motorcycle style meets 70s singer aesthetic. “It seems like I’m in the 1970s and I should have a boyfriend with a big tache.” A biker reference, I say, referencing the picture. “They used to call me that!” She beams. Jessie is sharp-witted, 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. When performing I often tease the audience.”

Medical Challenges and Discovery

The artist was preparing for an appearance at the Baftas when she noticed an abnormality. “I immediately went to get it checked, had an ultrasound, and they said, ‘It appears fine; your tissue is healthy.’ And I insisted, ‘But I can feel it. My arm hurts and pins and needles in my hands whenever I wake up.’ And they replied, ‘Well, let’s just do a biopsy?’ The date was March 28, the post-birthday.” It was a weekend eve. The doctor told her if it was serious she’d call on the Monday. By then Cornish had assured herself it was fine. The way she explains it, it was simply too inconvenient to face illness when she had a busy schedule.

“We’re two weeks away from debuting the project after a long hiatus and no new music. And the doctor messaged 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 believing it’s all going to be positive, and she informs me, ‘You might want to sit.’ The solemn tone? And she continues, ‘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.’ The first thing I thought was, ‘I can’t die because my son needs me.’”

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

She viewed the procedure frightening and surreal. “I fear going under. You’re escorted. During crises you roll down in a bed, but now I just marched with a medical attire and my backside out. Like a dystopian scene.” But, Cornish says, she’s been fortunate. No chemotherapy or radiation, just the op. “Cancer is awful, but you know what? I’m grateful it was caught soon. I underwent removal four months ago and my affected breast now resembles a grapefruit under a tight bedsheet.” She smiles again. “I got to keep the nipple, though.”

The follow-up procedure is for health and appearance. Her boobs, she notes, are now “different sizes. The size doesn’t match. How rude! I reflected, no need to bully me, I’m already having a hard period. So rude! Amusingly I said I’d never get my boobs done because I’ve got perfectionism, and I know they’d never be perfect. My plans were disrupted.”

A History of Health Challenges

Cornish is accustomed to medical issues. She thinks her attitude toward illness has been so upbeat because she’s experienced in medical emergencies. Frequently they align with professional successes, acting as a reminder, or punch in the stomach, to remind her not to assume everything is fine. “Frankly, I feel the universe whispers, ‘You having a good time? Hold on.’ Since childhood, it has consistently accompanied high points for me; something severe or obscure has impacted my body.”

She recalls to her 11-year-old self, already starting her career starring in the West End in Whistle Down the Wind (she was chosen at the age of nine). That’s when she was found to have the heart condition Wolff-Parkinson-White syndrome, which can cause a tachycardia as well as dizziness and palpitations. “I was going in and out of rehearsals on an intravenous line, and returning to the hospital at night.” She jumps ahead several years, and 17-year-old Jess has become part of the girl group Soul Deep while attending the Brit School. “I secured a deal, and I had a cerebral event. Then when I was planning to release songs in 2020 I had a collision and my voice box shifted and I couldn’t sing for a twelve months.”

Wow, I say, slow down, I need a moment. At just 17? She nods|agrees
