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

You wouldn’t believe it, Jessie J remarks. At that moment preparing for her first album release in eight years, deeply enamored with her newish partner, and at long last the mother of a toddler after dealing with conception issues for ten years, riding high. Suddenly in spring she was diagnosed with a breast cancer diagnosis.

The singer-songwriter, birth name Jessica Cornish, is famous for telling it as it is. The record, Don’t Tease Me With a Good Time, was intended as an candid account, addressing every bit of hardship she’d endured since she last recorded music (endometrial issues, pregnancy loss, broken romances, psychological manipulation, suicidal thoughts) with typical candour. The first single, her single No Secrets, was released in April. But by then there remained a major undisclosed truth. Her diagnosis. Later next release, the upbeat Living My Best Life, came out in May and Cornish was talking to press about how she was thriving, while all the while dealing with the disease. Subsequently she shared the news, and in July she had a mastectomy.

She gives me her best “Are you kidding?” glance. “I put out with a song called the track No Secrets. I’m giving every media appearance, and they inquire, ‘So what’s new with you?’ and I’m, like, ‘Well, not much…’” Cornish has just had to postpone shows because she’s yet to undergo follow-up surgery.

Our interview takes place at a studio in the capital. She is dressed in a beige fake-leather jacket, denim trousers with ornate white designs, beige footwear and big frames. Picture biker chic meets 70s singer aesthetic. “It seems like I’m in the seventies and I should have a man with facial hair.” A biker reference, I say, thinking of the film. “They used to call me that!” She smiles. Cornish is sharp-witted, unfiltered and blunt. She says she has always fancied doing comedy and is aiming for her standup debut soon. “I like entertaining. On stage I frequently joke about the crowd.”

Health Struggles and Diagnosis

She was preparing for an slot at the ceremony when she discovered a mass. “I quickly sought to get it looked at, had an test, and they were, like, ‘It seems benign; your tissue is healthy.’ And I was, like, ‘Yet I sense it. I have arm pain and pins and needles in my hands whenever I get up.’ And they replied, ‘Well, let’s just do a biopsy?’ It happened on March 28, the following my birthday.” It was a weekend eve. The physician told her if it was serious she’d call on the Monday. By then she had convinced herself it was okay. The way she describes it, it was just bad timing to face illness when she had many commitments.

“We’re two weeks away from debuting the project after eight years without an album and four years without a single. And the doctor messaged and said, ‘Can you talk at six?’ And I was, like, ‘A video call, likely minor.’ So I join the call believing it’s all going to be good, and she goes, ‘Are you sitting down?.’ That sympathetic voice? And she continues, ‘I’m so, so sorry but your reports have come back as malignant cells.’” What was your reaction? “I replied, ‘Well, that’s not great. What awful timing.’ The first thing I thought was, ‘I can’t die because my son needs me.’”

Some men find me challenging due to my self-awareness

She considered the operation frightening and surreal. “I fear going 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 fortunate. No chemotherapy or radiation, just the procedure. “Cancer sucks, man, but yet Luckily it was detected early. I had the mastectomy recently and my right breast now resembles a grapefruit under a tight bedsheet.” She smiles again. “At least the nipple remains.”

The follow-up procedure is for health and appearance. Her chest, she remarks, are now “uneven. The size doesn’t match. That’s impolite! I felt, why make it worse, I’m already having a hard period. Such disrespect! It’s funny because I said I’d never get my boobs done because I’ve got perfectionism, and I know they’d never be flawless. Illness changed that.”

A History of Health Challenges

Cornish is familiar with health problems. She believes her outlook on her diagnosis has been so upbeat because she’s familiar with physical challenges. Frequently they align with professional successes, serving as a tap on the shoulder, or blow, to remind her not to assume everything is fine. “Frankly, I feel life goes, ‘You having a good time? Sit down.’ Since childhood, it has often paired with moments of success for me; a serious or unusual issue has affected my well-being.”

She takes me back to her 11-year-old self, already starting her career featuring in the London theater in the production (she was cast at the age of nine). That’s when she was told about the cardiac issue a syndrome, which can cause a rapid pulse as well as vertigo and palpitations. “I was going in and out of rehearsals on an drip, and being readmitted at night.” She skips forward six years, and 17-year-old Jess has joined the trio Soul Deep while studying at the performing arts school. “I signed my initial contract, and I had a stroke. Then when I was planning to release songs in recently I had a automobile accident and my larynx moved up and I was unable to vocalize for a year.”

Wow, I say, hold on, I can’t keep up. A stroke so young? She nods|agrees
