‘It has pushed me to live more fully’: Jessie J on cancer, comebacks and cracking China

You couldn’t make it up, Jessie J remarks. There she was preparing for her new album launch in nearly a decade, ecstatically in love with her newish partner, and finally the parent to a young child after dealing with conception issues for ten years, feeling invincible. Then in March she was told she had a breast cancer diagnosis.

The artist, birth name Jessica Cornish, is famous for being brutally honest. The record, her latest release, was intended as an open book, addressing every ounce of devastation she’d faced since she last recorded music (a gynecological condition, pregnancy loss, unsuccessful partnerships, emotional abuse, mental health struggles) with typical candour. The lead track, No Secrets, was launched in April. But by then there existed a huge secret. The cancer. Then next release, her song Living My Best Life, was released in May and she was giving interviews about how she was enjoying life to the fullest, while still secretly dealing with her cancer. Subsequently she disclosed her condition, and in early July she had a mastectomy.

She gives me her best “Are you kidding?” glance. “I release with a song called the track No Secrets. I’m giving every media appearance, and they inquire, ‘What’s happening?’ and I respond, ‘Uh, nothing really’” she has just had to postpone shows because she’s yet to undergo follow-up surgery.

We meet at a photo studio in London. She is sporting a light brown synthetic jacket, denim trousers with ornate white designs, beige footwear and oversized specs. Think rocker vibe meets 1970s Nana Mouskouri. “I feel like I’m in the seventies and I should have a man with facial hair.” Like the film, I say, referencing the film. “I was nicknamed that in school!” She smiles. Cornish is quick, bold and filter-free. She says she has always been interested in humor and is hoping to make her initial standup show soon. “I like entertaining. When performing I often tease the crowd.”

Health Struggles and Diagnosis

She was getting ready for an slot at the Baftas when she noticed an abnormality. “I promptly visited to get it checked, had an ultrasound, and they told me, ‘It appears fine; your breasts are normal.’ And I insisted, ‘However, it’s there. I’ve got an achy arm and pins and needles in my hands whenever I get up.’ And they suggested, ‘We should biopsy it?’ That was 28 March, the day after my birthday.” It was a Friday. The physician told her if it was concerning she’d contact on the start of the week. By then Cornish had convinced herself it was nothing. The way she explains it, it was simply too inconvenient to face illness when she had a busy schedule.

“Just two weeks before from releasing the album after years away and an extended break. And she [the doctor] texted and said, ‘Is six okay?’ And I assumed, ‘It’s virtual, probably routine.’ So I log in thinking it’s all going to be fine, and she says, ‘Are you sitting down?.’ The solemn tone? And she says, ‘I’m so, so sorry but your biopsy results have come back as high-grade cancer cells.’” What did you say? “I answered, ‘Well, that’s not great. 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 considered the operation frightening and surreal. “I hate being put under. They walk you down. In urgent cases you roll down in a bed, but now I just walked with a gown on and my rear exposed. You feel like you’re in an episode of Black Mirror.” But, she adds, she’s been lucky. No chemotherapy or radiation, just the op. “It’s terrible, but yet Thank fuck I found it early. The surgery happened a few months back and my right breast now resembles a fruit under fabric.” Another grin. “The nipple was preserved.”

The next operation is for health and appearance. Her breasts, 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 rough time. Such disrespect! Ironically I said I’d not undergo augmentation because I’ve got OCD, and I know they’d never be flawless. Illness changed that.”

A History of Health Challenges

The singer is no stranger to illness. She believes her outlook on her diagnosis has been so optimistic because she’s experienced in medical emergencies. Many times they occur alongside peak moments, acting as a reminder, or punch in the stomach, to remind her not to assume everything is fine. “Frankly, I feel fate says, ‘Things going well? Sit down.’ Since childhood, it has consistently accompanied high points for me; something severe or obscure has happened to my health.”

She takes me back to her childhood, already starting her career performing in the London theater in Whistle Down the Wind (she was selected at the age of nine). That’s when she was found to have the medical problem WPW, which can cause a tachycardia as well as dizziness and palpitations. “I was going in and out of rehearsals on an drip, and going back into hospital at night.” She skips forward six years, and teenage Jess has entered the female band Soul Deep while studying at the Brit School. “I secured a deal, and I had a stroke. Then when I was planning to release songs in recently I had a automobile accident and my voice box shifted and I couldn’t sing for a twelve months.”

Oi, I say, hold on, I can’t keep up. At just 17? She nods|agrees
