‘It has made me live life more’: Jessie J on cancer, comebacks and conquering the Chinese market

You wouldn’t believe it, the singer states. There she was readying for her first album release in nearly a decade, blissfully happy with her newish partner, and at long last the parent to a young child after dealing with conception issues for a decade, on top of the world. Then in spring she was told she had cancer in her breast.

The singer-songwriter, actual name Jess Cornish, is famous for being brutally honest. The record, her latest release, was meant as an transparent story, dealing with every bit of hardship she’d endured since she last made an album (a gynecological condition, losing a baby, unsuccessful partnerships, psychological manipulation, mental health struggles) with typical candour. The initial release, her single No Secrets, was launched in the spring. But by then there was a mighty secret. Her diagnosis. Later follow-up track, Living My Best Life, came out in May and she was giving interviews about how she was living her best life, while all the while dealing with her cancer. A month later she went public, and in the start of summer she had a mastectomy.

She gives me her best “What the fuck?” expression. “I release with a song called No Secrets. I’m giving every press talk, and they ask, ‘So what’s new with you?’ and I respond, ‘Erm, yeah, nothing …’” she has just had to call off performances because she’s awaiting reconstructive surgery.

We’re at a studio in London. She is wearing a light brown synthetic jacket, denim trousers with ornate white designs, cream boots and big frames. Think biker chic meets 70s singer aesthetic. “It seems like I’m in the 1970s and I should have a man with facial hair.” A biker reference, I say, recalling the picture. “That’s what people called me at school!” She grins. Jessie is quick, irreverent and direct. She says she has always fancied doing comedy and is aiming for her first comedy performance next year. “I like entertaining. On stage I frequently joke about the fans.”

Health Struggles and Diagnosis

The artist was planning an performance at the Baftas when she noticed an abnormality. “I quickly sought to get it examined, had an test, and they told me, ‘It seems benign; your breasts are normal.’ And I responded, ‘However, it’s there. I have arm pain and pins and needles in my hands whenever I rise.’ And they replied, ‘We should biopsy it?’ The date was March 28, the following my birthday.” It was a weekend eve. The physician told her if it was serious she’d contact on the start of the week. By then she had convinced herself it was nothing. The way she describes it, it was inopportune to face illness when she had many commitments.

“It was a fortnight prior from launching this thing after years away and an extended break. And the doctor messaged and said, ‘Is six okay?’ And I was, like, ‘A video call, likely minor.’ So I join the call thinking it’s all going to be good, and she says, ‘Are you sitting down?.’ The solemn tone? And she continues, ‘I’m so, so sorry but your reports have come back as malignant cells.’” How did you respond? “I replied, ‘Well, that’s not great. What awful timing.’ My initial thought was, ‘My child depends on me.’”

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

She found the surgery frightening and surreal. “I fear going under. You’re escorted. You know when you have emergency surgery you are wheeled, but then I just walked with a medical attire and my bum hanging out. Like a dystopian scene.” But, Cornish says, she’s been blessed. Without chemo or radio, just the op. “Cancer is awful, but however I’m grateful it was caught soon. I underwent removal a few months back and my affected breast now resembles a fruit under fabric.” A further beam. “The nipple was preserved.”

The next operation is therapeutic and aesthetic. Her chest, she notes, are now “uneven. The size doesn’t match. How rude! I reflected, don’t add insult to injury, I’m already having a hard period. So rude! Amusingly I said I’d avoid breast surgery because I’ve got OCD, and I know they’d never be perfect. Illness changed that.”

Previous Struggles

She is familiar with health problems. She believes her outlook on her diagnosis has been so optimistic because she’s used to medical emergencies. They have often coincided with career highs, functioning as a wake-up call, or shock, to remind her not to be complacent. “Frankly, I feel the universe whispers, ‘Enjoying yourself? Hold on.’ Since childhood, it has consistently accompanied achievements for me; something severe or obscure has impacted my body.”

She takes me back to her 11-year-old self, already starting her career featuring in the stage in Whistle Down the Wind (she was cast at the age of nine). That’s when she was diagnosed with the heart condition Wolff-Parkinson-White syndrome, which can cause a fast heartbeat as well as vertigo and palpitations. “I was going in and out of rehearsals on an intravenous line, and returning to the hospital at night.” She fast-forwards several years, and 17-year-old Jess has joined the female band the group while attending the Brit School. “I signed my initial contract, and I had a brain incident. Then when I was planning to release songs in recently I had a collision and my voice box shifted and I lost my voice for a twelve months.”

Wow, I say, slow down, I can’t keep up. At just 17? She nods|agrees
