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

You can’t imagine it, the singer states. At that moment preparing for her new album launch in eight years, ecstatically in love with her recent boyfriend, and at long last the mom to a little one after dealing with conception issues for a decade, on top of the world. Then in March she was found to have breast cancer.

The singer-songwriter, actual name Jess Cornish, is renowned for being brutally honest. The album, Don’t Tease Me With a Good Time, was meant as an transparent story, tackling every ounce of devastation she’d faced since she last worked on songs (endometrial issues, pregnancy loss, unsuccessful partnerships, emotional abuse, suicidal thoughts) with typical candour. The initial release, No Secrets, was released in the spring. But by then there remained a major undisclosed truth. The illness. Then second single, Living My Best Life, came out in May and she was giving interviews about how she was thriving, while still secretly dealing with breast cancer. Four weeks after she disclosed her condition, and in early July she received surgical treatment.

She offers me her best “Are you kidding?” glance. “I come out with a song called No Secrets. I’m doing every media appearance, and they inquire, ‘What’s happening?’ and I’m, like, ‘Uh, nothing really’” she has just had to call off performances because she’s still waiting for reconstructive surgery.

Our interview takes place at a photography studio in London. She is wearing a beige fake-leather jacket, denim trousers with elaborate white patches, beige footwear and big frames. Picture rocker vibe meets 1970s Nana Mouskouri. “It seems like I’m in the 1970s and I should have a boyfriend with a big tache.” Like the film, I say, referencing the film. “They used to call me that!” She smiles. She is quick, bold and direct. She says she has always been interested in humor and is aiming for her first comedy performance in the coming year. “I enjoy humor. During performances I basically roast the crowd.”

Medical Challenges and Discovery

She was preparing for an slot at the Baftas when she found a lump. “I quickly sought to get it checked, had an scan, and they told me, ‘It appears fine; your breasts are normal.’ And I was, like, ‘But I can feel it. My arm hurts and numbness in my fingers whenever I rise.’ And they replied, ‘Well, let’s just do a biopsy?’ It happened on March 28, the day after my birthday.” It was a Friday. The doctor told her if it was concerning she’d call on the start of the week. By then Cornish had assured herself it was fine. The way she describes it, it was just bad timing to receive a diagnosis when she had many commitments.

“It was a fortnight prior from releasing the album after a long hiatus and no new music. And the doctor messaged and said, ‘Can you talk at six?’ And I assumed, ‘It’s virtual, probably routine.’ So I log in expecting it’s all going to be fine, and she goes, ‘You might want to sit.’ The solemn tone? And she continues, ‘Unfortunately but your biopsy results have shown high-grade cancer cells.’” What did you say? “I answered, ‘Oh, that’s not ideal, is it?. That’s not fucking great timing.’ My initial thought was, ‘My child depends on me.’”

I’ve been labeled difficult for knowing myself

She considered the operation scary and bizarre. “I fear going under. You’re escorted. In urgent cases you go on a gurney, but this time I just strolled down with a hospital gown and my rear exposed. It felt surreal.” But, Cornish says, she’s been fortunate. No chemo, no radiotherapy, just the op. “Cancer sucks, man, but yet Luckily it was detected early. I had the mastectomy recently and my affected breast now looks like a fruit under fabric.” Another grin. “I got to keep the nipple, though.”

The follow-up procedure is both medical and cosmetic. Her boobs, she remarks, are now “different sizes. They didn’t do an implant as small as my original. That’s impolite! I reflected, why make it worse, I’m already having a rough time. Such disrespect! Amusingly I said I’d not undergo augmentation because I’ve got obsessive tendencies, and I know they’d never be flawless. My plans were disrupted.”

Past Medical Issues

She is familiar with health problems. She thinks her outlook on her diagnosis has been so positive because she’s familiar with physical challenges. They have often coincided with peak moments, acting as a reminder, or shock, to make her recall not to assume everything is fine. “Honestly, I feel fate says, ‘You having a good time? Sit down.’ From a young age, it has consistently accompanied high points for me; a serious or unusual issue has happened to my health.”

She reminisces to her 11-year-old self, already making her debut featuring in the stage in the production (she was cast at the age of nine). That’s when she was told about the heart condition a syndrome, which can cause a rapid pulse as well as dizziness and palpitations. “I attended rehearsals intermittently on an drip, and being readmitted at night.” She jumps ahead six years, and 17-year-old Jess has become part of the female band Soul Deep while attending the academy. “I just got my first record deal, and I had a cerebral event. Then when I was ready to debut in 2020 I had a collision and my throat was injured and I couldn’t sing for a twelve months.”

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