Honest Memo

‘It has taught me to embrace life more’: Jessie J on cancer, career returns and cracking China

You can’t imagine it, the singer remarks. There she was preparing for her new album launch in eight years, blissfully happy with her recent boyfriend, and finally the mother of a toddler after dealing with conception issues for a decade, feeling invincible. Then in March she was found to have a breast cancer diagnosis.

The singer-songwriter, actual name J. Cornish, is renowned for being brutally honest. The album, her latest release, was intended as an open book, dealing with every ounce of devastation she’d endured since she last worked on songs (endometriosis, losing a baby, broken romances, emotional abuse, suicidal thoughts) with characteristic openness. The lead track, the song No Secrets, was released in April. But by then there existed a huge secret. Her diagnosis. Later next release, her song Living My Best Life, was released in May and the artist was talking to press about how she was thriving, while all the while dealing with her cancer. A month later she disclosed her condition, and in July she had a mastectomy.

She shoots me her best “Seriously?” look. “I release with a song called the track No Secrets. I’m giving every press talk, and they inquire, ‘So what’s new with you?’ 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 oversized specs. Picture biker chic meets 70s singer aesthetic. “As if I’m in the seventies and I should have a boyfriend with a big tache.” A biker reference, I say, thinking of the movie. “I was nicknamed that in school!” She beams. She is quick, irreverent and blunt. She says she has always fancied doing comedy and is hoping to make her first comedy performance soon. “I love making people laugh. During performances I often tease the fans.”

Medical Challenges and Discovery

Cornish was planning an appearance at the Baftas when she found a lump. “I promptly visited to get it looked at, had an scan, and they said, ‘It looks like nothing; your breasts are normal.’ And I responded, ‘Yet I sense it. I have arm pain and tingling in my hands whenever I wake up.’ And they said, ‘How about a biopsy?’ It happened on March 28, the day after my birthday.” It was a weekend eve. The physician told her if it was bad news she’d reach out on the Monday. By then she had assured herself it was fine. The way she tells it, it was just bad timing to receive a diagnosis when she had many commitments.

“Just two weeks before from launching this thing after years away and four years without a single. And the doctor messaged and said, ‘Are you free at six?’ And I assumed, ‘A video call, likely minor.’ So I jump on the Zoom expecting it’s all going to be fine, and she informs me, ‘You might want to sit.’ That sympathetic voice? And she reveals, ‘I’m so, so sorry but your test results have come back as high-grade cancer cells.’” What did you say? “I replied, ‘Well, that’s not great. What awful timing.’ Immediately I felt was, ‘My child depends on me.’”

Some men find me challenging due to my self-awareness

She found the surgery terrifying and absurd. “I dislike anesthesia. They walk you down. During crises you go on a gurney, but now I just strolled down with a gown on and my rear exposed. It felt surreal.” But, she adds, she’s been fortunate. No chemo, no radiotherapy, just the procedure. “It’s terrible, but yet I’m grateful it was caught soon. The surgery happened four months ago and my one side now resembles a fruit under fabric.” Another grin. “The nipple was preserved.”

The subsequent surgery is for health and appearance. Her boobs, she notes, are now “different sizes. The size doesn’t match. How rude! I felt, don’t add insult to injury, I’m already having a difficult experience. Such disrespect! It’s funny because I said I’d avoid breast surgery because I’ve got OCD, and I know they’d never be ideal. Cancer ruined that plan.”

A History of Health Challenges

Cornish is familiar with health problems. She feels her attitude toward illness has been so positive because she’s experienced in health crises. Many times they occur alongside professional successes, acting as a reminder, or punch in the stomach, to remind her not to assume everything is fine. “Truly, I feel life goes, ‘Enjoying yourself? Hold on.’ Since childhood, it has often paired with high points for me; a serious or unusual issue has affected my well-being.”

She recalls to her youth, already beginning starring in the West End in a musical (she was selected at the age of nine years old). That’s when she was diagnosed with the medical problem a syndrome, which can cause a tachycardia as well as dizziness and heart flutters. “I attended rehearsals intermittently on an drip, and going back into hospital at night.” She jumps ahead several years, and young Jessica has become part of the girl group Soul Deep while attending the academy. “I signed my initial contract, and I had a stroke. Then when I was about to put out music in recently I had a collision and my voice box shifted and I lost my voice for a twelve months.”

Wow, I say, wait, I am overwhelmed. You really had a stroke at 17? She nods|agrees
