‘It has made me live life more’: Jessica Cornish on her health battle, comebacks and conquering the Chinese market

You couldn’t make it up, Jessie J remarks. At that moment readying for her new album launch in eight years, blissfully happy with her recent boyfriend, and at long last the parent to a young child after dealing with conception issues for ten years, feeling invincible. Then in March she was told she had breast cancer.

The artist, real name Jessica Cornish, is known for speaking her mind. The LP, her latest release, was meant as an transparent story, tackling every moment of pain she’d experienced since she last made an album (endometrial issues, miscarriage, broken romances, psychological manipulation, suicidal thoughts) with characteristic openness. The lead track, her single No Secrets, was dropped in the spring. But by then there remained a major undisclosed truth. The cancer. Later follow-up track, the upbeat Living My Best Life, came out in late spring and Cornish was speaking publicly about how she was enjoying life to the fullest, while still secretly coping with breast cancer. Four weeks after she went public, and in the start of summer she had a mastectomy.

She shoots me her best “What the fuck?” look. “I release with a song called No Secrets. I’m giving every media appearance, and they’re, like, ‘Any updates?’ and I answer, ‘Uh, nothing really’” Cornish has just had to cancel tour dates because she’s yet to undergo follow-up surgery.

Our interview takes place at a studio in London. She is sporting a light brown synthetic jacket, denim trousers with detailed white appliqués, beige footwear and oversized specs. Imagine biker chic meets 1970s Nana Mouskouri. “It seems like I’m in the seventies and I should have a partner with a mustache.” A biker reference, I say, thinking of the movie. “I was nicknamed that in school!” She grins. She is quick, unfiltered and filter-free. She says she has always been interested in humor and is aiming for her first comedy performance in the coming year. “I like entertaining. On stage I basically roast the fans.”

Medical Challenges and Discovery

The artist was preparing for an appearance at the Baftas when she discovered a mass. “I immediately went to get it checked, had an scan, and they said, ‘It looks like nothing; your breasts are normal.’ And I was, like, ‘Yet I sense it. My arm hurts and pins and needles in my hands whenever I wake up.’ And they replied, ‘We should biopsy it?’ It happened on March 28, the post-birthday.” It was a weekend eve. The specialist told her if it was serious she’d contact on the start of the week. By then she had convinced herself it was okay. The way she tells it, it was simply too inconvenient to get cancer when she had many commitments.

“We’re two weeks away from releasing the album after a long hiatus and an extended break. And she contacted me 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 thinking it’s all going to be fine, and she says, ‘You might want to sit.’ You know that sad tone they use? And she says, ‘I’m so, so sorry but your biopsy results have indicated aggressive cancer.’” What did you say? “I replied, ‘Oh, that’s not ideal, is it?. What awful timing.’ The first thing I thought was, ‘I have to survive for my boy.’”

Some men find me challenging due to my self-awareness

She viewed the procedure frightening and surreal. “I fear going under. They walk you down. During crises you roll down in a bed, but this time I just walked with a gown on and my bum hanging out. You feel like you’re in an episode of Black Mirror.” But, she adds, she’s been fortunate. No chemo, no radiotherapy, just the op. “Cancer sucks, man, but you know what? Luckily it was detected early. I had the mastectomy four months ago and my affected breast now looks like a grapefruit under a tight bedsheet.” She smiles again. “I got to keep the nipple, though.”

The follow-up procedure is therapeutic and aesthetic. Her boobs, she remarks, are now “different sizes. The implant is larger than before. That’s impolite! I felt, why make it worse, I’m already having a difficult experience. So rude! Ironically I said I’d not undergo augmentation because I’ve got obsessive tendencies, and I know they’d never be perfect. Cancer ruined that plan.”

Previous Struggles

She is familiar with health problems. She feels her outlook on her diagnosis has been so upbeat because she’s experienced in physical challenges. Many times they occur alongside career highs, serving as a tap on the shoulder, or blow, to highlight not to assume everything is fine. “Frankly, I feel life goes, ‘You having a good time? Take a seat.’ From a young age, it has consistently accompanied high points for me; a serious or unusual issue has affected my well-being.”

She reminisces to her childhood, already starting her career starring in the stage in the production (she was cast at the age of nine years old). That’s when she was diagnosed with the cardiac issue WPW, which can cause a rapid pulse as well as vertigo and heart flutters. “I attended rehearsals intermittently on an drip, and going back into hospital at night.” She skips forward several years, and 17-year-old Jess has become part of the trio the group while attending the Brit School. “I just got my first record deal, and I had a stroke. Then when I was about to put out music in the year 2020 I had a collision and my throat was injured and I lost my voice for a year.”

Oi, I say, hold on, I am overwhelmed. At just 17? She nods|agrees
