‘It has made me live life more’: Jessica Cornish on cancer, comebacks and cracking China

You can’t imagine it, 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 mother of a toddler after facing fertility challenges for ten years, riding high. Then in March she was told she had breast cancer.

The artist, birth name Jess Cornish, is renowned for being brutally honest. The album, her latest release, was supposed to be an open book, tackling every moment of pain she’d experienced since she last worked on songs (endometriosis, losing a baby, failed relationships, emotional abuse, suicidal thoughts) with typical candour. The lead track, the song No Secrets, was released in the spring. But by then there existed a huge secret. Her diagnosis. Then second single, the upbeat Living My Best Life, debuted in May and she was giving interviews about how she was thriving, while all the while coping with the disease. Subsequently she went public, and in July she received surgical treatment.

She gives me her best “What the fuck?” glance. “I come out with a song called No Secrets. I’m conducting every interview, and they ask, ‘What’s happening?’ and I’m, like, ‘Uh, nothing really’” Cornish has just had to call off performances because she’s awaiting follow-up surgery.

We meet at a studio in London. She is wearing a light brown synthetic jacket, jeans with detailed white appliqués, cream boots and big frames. Imagine rocker vibe meets 70s singer aesthetic. “I feel like I’m in the 1970s and I should have a man with facial hair.” Easy Rider, I say, recalling the film. “They used to call me that!” She smiles. Jessie is sharp-witted, irreverent and filter-free. She says she has always wanted to try comedy and is hoping to make her initial standup show next year. “I love making people laugh. During performances I often tease the crowd.”

Personal Battles and News

She was preparing for an performance at the ceremony when she found a lump. “I immediately went to get it examined, had an test, and they said, ‘It seems benign; you’ve got really good dense breast tissue.’ And I insisted, ‘However, it’s there. My arm hurts and numbness in my fingers whenever I rise.’ And they replied, ‘Well, let’s just do a biopsy?’ That was 28 March, the day after my birthday.” It was a Friday. The specialist told her if it was serious she’d call on the start of the week. By then the singer had persuaded herself it was okay. The way she describes it, it was just bad timing to get cancer when she had so much on.

“Just two weeks before from debuting the project after eight years without an album and an extended break. And she [the doctor] texted and said, ‘Are you free at six?’ And I assumed, ‘It’s virtual, probably routine.’ So I jump on the Zoom thinking it’s all going to be positive, and she says, ‘Please take a seat.’ That sympathetic voice? And she says, ‘I’m so, so sorry but your test results have shown aggressive cancer.’” What did you say? “I said, ‘That’s unfortunate. What awful timing.’ My initial thought was, ‘I can’t die because my son needs me.’”

Some men find me challenging due to my self-awareness

She considered the operation terrifying and absurd. “I dislike anesthesia. You’re escorted. In urgent cases you are wheeled, but then I just marched with a hospital gown and my rear exposed. Like a dystopian scene.” But, she notes, she’s been lucky. No chemotherapy or radiation, just the procedure. “It’s terrible, but however I’m grateful it was caught soon. The surgery happened recently and my right breast now looks like a odd shape.” Another grin. “At least the nipple remains.”

The follow-up procedure is therapeutic and aesthetic. Her chest, she notes, are now “uneven. The size doesn’t match. That’s impolite! I reflected, no need to bully me, I’m already having a difficult experience. How offensive! 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.”

A History of Health Challenges

She is familiar with health problems. She feels her perspective on the cancer has been so positive because she’s experienced in health crises. Many times they occur alongside career highs, acting as a reminder, or shock, to highlight not to assume everything is fine. “Frankly, I feel fate says, ‘You having a good time? Hold on.’ Since childhood, it has often paired with moments of success for me; something severe or obscure has happened to my health.”

She recalls to her 11-year-old self, already starting her career featuring in the stage in the production (she was chosen at the age of 9). That’s when she was found to have the heart condition Wolff-Parkinson-White syndrome, which can cause a tachycardia as well as lightheadedness and heart flutters. “I rehearsed between visits on an IV drip, and being readmitted at night.” She skips forward half a dozen years, and teenage Jess has joined the girl group Soul Deep while studying at the academy. “I secured a deal, and I had a brain incident. Then when I was ready to debut in recently I had a automobile accident and my throat was injured and I was unable to vocalize for a twelve months.”

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