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

You wouldn’t believe it, Jessie J says. At that moment preparing for her new album launch in eight years, deeply enamored with her recent boyfriend, and at long last the mom to a little one after facing fertility challenges for ten years, on top of the world. Then in spring she was found to have breast cancer.

The musician, birth name Jess Cornish, is renowned for telling it as it is. The album, her latest release, was meant as an candid account, addressing every bit of hardship she’d faced since she last worked on songs (a gynecological condition, losing a baby, broken romances, psychological manipulation, suicide) with typical candour. The initial release, No Secrets, was launched in the spring. But by then there remained a major undisclosed truth. The cancer. Then next release, the upbeat Living My Best Life, was released in late spring and she was talking to press about how she was thriving, while still secretly coping with the disease. Four weeks after she disclosed her condition, and in early July she had a mastectomy.

She shoots me her best “What the fuck?” look. “I release with a song called No Secrets. I’m conducting every media appearance, and they’re, like, ‘What’s happening?’ and I answer, ‘Erm, yeah, nothing …’” the singer has just had to cancel tour dates because she’s awaiting cosmetic procedures.

We’re at a photo studio in the capital. She is sporting a tan faux-leather coat, denim trousers with elaborate white patches, cream boots and large glasses. Think rocker vibe meets vintage look. “It seems like I’m in the 1970s and I should have a partner with a mustache.” Easy Rider, I say, recalling the film. “I was nicknamed that in school!” She smiles. Cornish is quick, bold and direct. She says she has always been interested in humor and is aiming for her standup debut in the coming year. “I like entertaining. When performing I frequently joke about the fans.”

Medical Challenges and Discovery

Cornish was preparing for an performance at the Baftas when she discovered a mass. “I quickly sought to get it checked, had an ultrasound, and they were, like, ‘It seems benign; you’ve got really good dense breast tissue.’ And I was, like, ‘Yet I sense it. My arm hurts and numbness in my fingers whenever I get up.’ And they replied, ‘How about a biopsy?’ It happened on March 28, the following my birthday.” It was a Friday. The specialist told her if it was concerning she’d reach out on the Monday. By then the singer had assured herself it was nothing. The way she explains it, it was just bad timing to face illness when she had a busy schedule.

“Just two weeks before from launching this thing after eight years without an album and four years without a single. And the doctor messaged and said, ‘Is six okay?’ And I thought, ‘It’s virtual, probably routine.’ So I log in thinking it’s all going to be positive, and she says, ‘Please take a seat.’ The solemn tone? And she says, ‘I’m so, so sorry but your reports have come back as high-grade cancer cells.’” How did you respond? “I answered, ‘That’s unfortunate. That’s not fucking great timing.’ My initial thought was, ‘I have to survive for my boy.’”

Some men find me challenging due to my self-awareness

She found the surgery terrifying and absurd. “I fear going under. They walk you down. During crises you are wheeled, but now I just strolled down with a hospital gown and my rear exposed. Like a dystopian scene.” But, she notes, she’s been fortunate. Without chemo or radio, just the procedure. “Cancer sucks, man, but you know what? I’m grateful it was caught soon. I underwent removal recently and my affected breast now resembles a grapefruit under a tight bedsheet.” A further beam. “The nipple was preserved.”

The next operation is therapeutic and aesthetic. Her chest, she notes, are now “different sizes. The size doesn’t match. That’s impolite! I thought, don’t add insult to injury, I’m already having a hard period. Such disrespect! Amusingly I said I’d not undergo augmentation because I’ve got obsessive tendencies, and I know they’d never be ideal. My plans were disrupted.”

Past Medical Issues

Cornish is familiar with health problems. She believes her perspective on the cancer has been so positive because she’s used to medical emergencies. Many times they occur alongside career highs, acting as a reminder, or blow, to remind her not to assume everything is fine. “Frankly, I feel fate says, ‘Things going well? Hold on.’ From a young age, it has consistently accompanied achievements for me; something severe or obscure has happened to my health.”

She reminisces to her childhood, already making her debut starring in the West End in the production (she was chosen at the age of nine years old). That’s when she was diagnosed with the heart condition a syndrome, which can cause a tachycardia as well as lightheadedness and palpitations. “I attended rehearsals intermittently on an IV drip, and going back into hospital at night.” She skips forward several years, and young Jessica has joined the female band the group while studying at the academy. “I just got my first record deal, and I had a cerebral event. Then when I was planning to release songs in the year 2020 I had a car crash and my voice box shifted and I lost my voice for a year.”

Wow, I say, slow down, I am overwhelmed. A stroke so young? She nods|agrees
