‘It has made me live life more’: Jessie J on cancer, career returns and cracking China

You couldn’t make it up, the singer states. At that moment readying for her comeback record in eight years, ecstatically in love with her recent boyfriend, and at long last the mom to a little one after struggling to conceive for ten years, feeling invincible. Suddenly in spring she was found to have breast cancer.

The singer-songwriter, birth name J. Cornish, is known for speaking her mind. The album, her latest release, was intended as an open book, tackling every bit of hardship she’d experienced since she last worked on songs (endometrial issues, pregnancy loss, unsuccessful partnerships, gaslighting, suicide) with her usual frankness. The lead track, her single No Secrets, was launched in the spring. But by then there remained a major undisclosed truth. The illness. Later second single, Living My Best Life, was released in May and the artist was talking to press about how she was enjoying life to the fullest, while at the same time dealing with the disease. Subsequently she shared the news, and in early July she received surgical treatment.

She shoots me her best “Seriously?” look. “I put out with a song called the track No Secrets. I’m doing every interview, and they’re, like, ‘So what’s new with you?’ and I’m, like, ‘Erm, yeah, nothing …’” the singer has just had to cancel tour dates because she’s yet to undergo reconstructive surgery.

We’re at a photography studio in London. She is dressed in a beige fake-leather jacket, jeans with detailed white appliqués, beige footwear and oversized specs. Think motorcycle style meets 1970s Nana Mouskouri. “I feel like I’m in the seventies and I should have a partner with a mustache.” A biker reference, I say, referencing the film. “I was nicknamed that in school!” She beams. Cornish is fast-thinking, unfiltered and direct. She says she has always fancied doing comedy and is planning to attempt her first comedy performance in the coming year. “I enjoy humor. When performing I often tease the fans.”

Medical Challenges and Discovery

She was planning an performance at the awards show when she discovered a mass. “I promptly visited to get it looked at, had an test, and they told me, ‘It seems benign; you’ve got really good dense breast tissue.’ And I insisted, ‘Yet I sense it. I’ve got an achy arm and pins and needles in my hands whenever I get up.’ And they suggested, ‘Well, let’s just do a biopsy?’ It happened on March 28, the post-birthday.” It was a weekend eve. The doctor told her if it was concerning she’d reach out on the start of the week. By then she had convinced herself it was fine. The way she explains it, it was just bad timing to get cancer when she had many commitments.

“Just two weeks before from releasing the album after years away and four years without a single. And the doctor messaged and said, ‘Are you free at six?’ And I thought, ‘Oh, it’s a Zoom, it won’t be anything.’ So I jump on the Zoom believing it’s all going to be good, and she informs me, ‘Please take a seat.’ The solemn tone? And she reveals, ‘I regret to inform you but your reports have come back as malignant cells.’” What was your reaction? “I said, ‘That’s unfortunate. That’s not fucking great timing.’ My initial thought was, ‘My child depends on me.’”

I’ve been labeled difficult for knowing myself

She viewed the procedure terrifying and absurd. “I hate being put under. They lead you. During crises you roll down in a bed, but now I just strolled down with a hospital gown and my backside out. It felt surreal.” But, she notes, she’s been blessed. Without chemo or radio, just the surgery. “Cancer is awful, but however Luckily it was detected early. I had the mastectomy recently and my one side now looks like a fruit under fabric.” A further beam. “The nipple was preserved.”

The follow-up procedure is for health and appearance. Her chest, she observes, are now “asymmetrical. The size doesn’t match. So inconsiderate! I thought, why make it worse, I’m already having a difficult experience. Such disrespect! Amusingly I said I’d never get my boobs done because I’ve got obsessive tendencies, and I know they’d never be flawless. Cancer ruined that plan.”

Past Medical Issues

She is familiar with health problems. She believes her perspective on the cancer has been so upbeat because she’s experienced in health crises. Frequently they align with peak moments, serving as a tap on the shoulder, or shock, to make her recall not to assume everything is fine. “Honestly, I feel the universe whispers, ‘Things going well? Sit down.’ From a young age, it has often paired with high points for me; a serious or unusual issue has happened to my health.”

She takes me back to her 11-year-old self, already starting her career starring in the West End in a musical (she was selected at the age of nine). That’s when she was diagnosed with the heart condition a syndrome, which can cause a rapid pulse as well as vertigo and palpitations. “I attended rehearsals intermittently on an intravenous line, and being readmitted at night.” She jumps ahead several years, and young Jessica has joined the girl group Soul Deep while enrolled in the academy. “I signed my initial contract, and I had a cerebral event. Then when I was about to put out music in the year 2020 I had a collision and my voice box shifted and I couldn’t sing for a long period.”

Oi, I say, slow down, I can’t keep up. You really had a stroke at 17? She nods|agrees
