‘It has taught me to embrace life more’: Jessie J on her health battle, career returns and conquering the Chinese market

You can’t imagine it, Jessie J states. At that moment gearing up 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 struggling to conceive for ten years, feeling invincible. Suddenly in March she was diagnosed with cancer in her breast.

The musician, actual name J. Cornish, is known for speaking her mind. The LP, her latest release, was intended as an open book, addressing every bit of hardship she’d faced since she last recorded music (a gynecological condition, pregnancy loss, failed relationships, psychological manipulation, suicide) with typical candour. The initial release, No Secrets, was dropped in April. But by then there remained a major undisclosed truth. Her diagnosis. Then follow-up track, Living My Best Life, debuted in May and the artist was giving interviews about how she was living her best life, while still secretly living with the disease. A month later she shared the news, and in early July she underwent breast removal surgery.

She shoots me her best “Seriously?” expression. “I put out with a song called No Secrets. I’m doing every media appearance, and they’re, like, ‘Any updates?’ and I respond, ‘Well, not much…’” the singer has just had to postpone shows because she’s awaiting reconstructive surgery.

We’re at a photo studio in the capital. She is sporting a tan faux-leather coat, denim trousers with detailed white appliqués, beige footwear and big frames. Picture rocker vibe meets vintage look. “As if I’m in the seventies and I should have a boyfriend with a big tache.” A biker reference, I say, referencing the film. “I was nicknamed that in school!” She grins. Cornish is sharp-witted, unfiltered and blunt. She says she has always wanted to try comedy and is hoping to make her standup debut soon. “I enjoy humor. On stage I basically roast the audience.”

Medical Challenges and Discovery

Cornish was preparing for an slot at the awards show when she noticed an abnormality. “I immediately went to get it examined, had an scan, and they said, ‘It looks like nothing; your tissue is healthy.’ And I responded, ‘Yet I sense it. I have arm pain and tingling in my hands whenever I wake up.’ And they said, ‘We should biopsy it?’ That was 28 March, the post-birthday.” It was a Friday. The doctor told her if it was serious she’d call on the start of the week. By then Cornish had persuaded herself it was okay. The way she tells it, it was just bad timing to get cancer when she had so much on.

“It was a fortnight prior from launching this thing after years away and no new music. And she [the doctor] texted and said, ‘Can you talk at six?’ And I thought, ‘It’s virtual, probably routine.’ So I log in believing it’s all going to be good, and she informs me, ‘You might want to sit.’ The solemn tone? And she reveals, ‘Unfortunately but your biopsy results have shown high-grade cancer cells.’” What was your reaction? “I replied, ‘Oh, that’s not ideal, is it?. What awful timing.’ My initial thought was, ‘I have to survive for my boy.’”

I’ve been labeled difficult for knowing myself

She found the surgery terrifying and absurd. “I dislike anesthesia. They walk you down. In urgent cases you roll down in a bed, but now I just strolled down with a gown on and my rear exposed. You feel like you’re in an episode of Black Mirror.” But, she notes, she’s been fortunate. No chemo, no radiotherapy, just the surgery. “Cancer sucks, man, but however Thank fuck I found it early. I had the mastectomy a few months back and my one side now appears as a odd shape.” She smiles again. “I got to keep the nipple, though.”

The next operation is both medical and cosmetic. Her boobs, she notes, are now “uneven. They didn’t do an implant as small as my original. That’s impolite! I reflected, no need to bully me, I’m already having a difficult experience. So rude! Amusingly I said I’d never get my boobs done because I’ve got obsessive tendencies, and I know they’d never be flawless. Illness changed that.”

Past Medical Issues

She is familiar with health problems. She feels her perspective on the cancer has been so positive because she’s experienced in medical emergencies. Frequently they align with career highs, functioning as a wake-up call, or blow, to make her recall not to take anything for granted. “Frankly, I feel life goes, ‘You having a good time? Take a seat.’ Ever since I was a child, it has consistently accompanied high points for me; a major or strange event has happened to my health.”

She takes me back to her 11-year-old self, already beginning starring in the London theater in a musical (she was selected at the age of nine years old). That’s when she was found to have the cardiac issue WPW, which can cause a tachycardia as well as lightheadedness and irregular beats. “I rehearsed between visits on an intravenous line, and going back into hospital at night.” She jumps ahead several years, and teenage Jess has entered the female band the group while attending the academy. “I just got my first record deal, and I had a stroke. Then when I was about to put out music in recently I had a collision and my throat was injured and I lost my voice for a year.”

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