‘It has made me live life more’: Jessica Cornish on her health battle, career returns and cracking China

You couldn’t make it up, Jessie J says. At that moment preparing for her comeback record in eight years, ecstatically in love with her newish partner, and at long last the mom to a little one after dealing with conception issues for a decade, feeling invincible. Then in March she was diagnosed with cancer in her breast.

The artist, birth name Jess Cornish, is renowned for speaking her mind. The record, Don’t Tease Me With a Good Time, was supposed to be an candid account, tackling every moment of pain she’d experienced since she last worked on songs (endometriosis, pregnancy loss, broken romances, emotional abuse, suicidal thoughts) with typical candour. The lead track, her single No Secrets, was launched in April. But by then there remained a major undisclosed truth. Her diagnosis. Later follow-up track, Living My Best Life, was released in late spring and the artist was talking to press about how she was thriving, while all the while dealing with breast cancer. A month later she went public, and in the start of summer she had a mastectomy.

She gives me her best “Seriously?” expression. “I release with a song called No Secrets. I’m giving every media appearance, and they ask, ‘What’s happening?’ and I answer, ‘Uh, nothing really’” the singer has just had to call off performances because she’s yet to undergo reconstructive surgery.

We meet at a photography studio in the capital. She is wearing a beige fake-leather jacket, blue jeans with ornate white designs, cream boots and oversized specs. Imagine biker chic meets 1970s Nana Mouskouri. “It seems like I’m in the seventies and I should have a man with facial hair.” A biker reference, I say, referencing the movie. “I was nicknamed that in school!” She smiles. Cornish is quick, bold and direct. She says she has always fancied doing comedy and is planning to attempt her first comedy performance soon. “I like entertaining. When performing I often tease the crowd.”

Health Struggles and Diagnosis

Cornish was planning an slot at the ceremony when she found a lump. “I promptly visited to get it examined, had an ultrasound, and they told me, ‘It appears fine; you’ve got really good dense breast tissue.’ And I responded, ‘But I can feel it. I’ve got an achy arm and numbness in my fingers whenever I get up.’ And they suggested, ‘Well, let’s just do a biopsy?’ That was 28 March, the post-birthday.” It was a weekend eve. The doctor told her if it was serious she’d reach out on the Monday. By then Cornish had convinced herself it was nothing. The way she explains it, it was just bad timing to get cancer when she had so much on.

“It was a fortnight prior from releasing the album after eight years without an album and an extended break. And the doctor messaged and said, ‘Can you talk at six?’ And I was, like, ‘It’s virtual, probably routine.’ So I jump on the Zoom thinking it’s all going to be positive, and she informs me, ‘Are you sitting down?.’ The solemn tone? And she reveals, ‘Unfortunately but your test results have shown aggressive cancer.’” How did you respond? “I replied, ‘That’s unfortunate. The timing is terrible.’ The first thing I thought was, ‘My child depends on me.’”

I’ve been labeled difficult for knowing myself

She considered the operation terrifying and absurd. “I fear going under. They walk you down. During crises you roll down in a bed, but then I just strolled down with a hospital gown and my bum hanging out. It felt surreal.” But, she adds, she’s been lucky. No chemotherapy or radiation, just the surgery. “It’s terrible, but you know what? Luckily it was detected early. I underwent removal a few months back and my affected breast now appears as a grapefruit under a tight bedsheet.” She smiles again. “The nipple was preserved.”

The next operation is therapeutic and aesthetic. Her breasts, she notes, are now “uneven. They didn’t do an implant as small as my original. So inconsiderate! I thought, no need to bully me, I’m already having a rough time. Such disrespect! Ironically I said I’d never get my boobs done because I’ve got OCD, and I know they’d never be flawless. Illness changed that.”

A History of Health Challenges

The singer is accustomed to medical issues. She feels her perspective on the cancer has been so optimistic because she’s experienced in health crises. They have often coincided with career highs, functioning as a wake-up call, or shock, to make her recall not to take anything for granted. “Frankly, I feel life goes, ‘Enjoying yourself? Sit down.’ Ever since I was a child, it has always gone alongside moments of success for me; a major or strange event has impacted my body.”

She recalls to her 11-year-old self, already making her debut performing in the stage in a musical (she was cast at the age of nine). That’s when she was diagnosed with the cardiac issue WPW, which can cause a rapid pulse as well as lightheadedness and heart flutters. “I rehearsed between visits on an intravenous line, and being readmitted at night.” She jumps ahead several years, and 17-year-old Jess has entered the girl group Soul Deep while studying at the Brit School. “I signed my initial contract, and I had a brain incident. Then when I was ready to debut in recently I had a collision and my larynx moved up and I lost my voice for a twelve months.”

Oi, I say, slow down, I can’t keep up. At just 17? She nods|agrees
