‘It has made me live life more’: Jessica Cornish on cancer, comebacks and cracking China

You can’t imagine it, the singer states. At that moment readying for her comeback record in eight years, deeply enamored with her newish partner, and finally the mom to a little one after facing fertility challenges for ten years, riding high. Then in March she was found to have cancer in her breast.

The musician, birth name J. Cornish, is renowned for telling it as it is. The LP, Don’t Tease Me With a Good Time, was supposed to be an open book, tackling every ounce of devastation she’d faced since she last made an album (endometriosis, miscarriage, failed relationships, gaslighting, suicide) with characteristic openness. The initial release, her single No Secrets, was dropped in April. But by then there was a mighty secret. Her diagnosis. Then second single, her song Living My Best Life, debuted in late spring and she was talking to press about how she was enjoying life to the fullest, while all the while coping with the disease. Four weeks after she shared the news, and in early July she had a mastectomy.

She offers me her best “What the fuck?” look. “I release with a song called the track No Secrets. I’m conducting every media appearance, and they inquire, ‘So what’s new with you?’ and I respond, ‘Well, not much…’” she 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 sporting a tan faux-leather coat, blue jeans with elaborate white patches, cream boots and oversized specs. Imagine biker chic meets vintage look. “I feel like I’m in the 1970s and I should have a partner with a mustache.” A biker reference, I say, referencing the movie. “I was nicknamed that in school!” She grins. Jessie is fast-thinking, bold and filter-free. She says she has always fancied doing comedy and is hoping to make her initial standup show in the coming year. “I enjoy humor. During performances I frequently joke about the fans.”

Health Struggles and Diagnosis

Cornish was getting ready for an performance at the Baftas when she noticed an abnormality. “I promptly visited to get it examined, had an ultrasound, and they said, ‘It seems benign; your breasts are normal.’ And I insisted, ‘But I can feel it. My arm hurts and numbness in my fingers 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 Friday. The doctor told her if it was concerning she’d reach out on the Monday. By then Cornish had assured herself it was okay. The way she explains it, it was inopportune to face illness when she had many commitments.

“We’re two weeks away from launching this thing after years away and an extended break. And the doctor messaged and said, ‘Is six okay?’ And I thought, ‘A video call, likely minor.’ So I join the call expecting it’s all going to be positive, and she says, ‘You might want to sit.’ The solemn tone? And she says, ‘Unfortunately but your test results have indicated aggressive cancer.’” What was your reaction? “I said, ‘That’s unfortunate. What awful timing.’ My initial thought was, ‘I have to survive for my boy.’”

Some men find me challenging due to my self-awareness

She viewed the procedure scary and bizarre. “I fear going under. You’re escorted. You know when you have emergency surgery you are wheeled, but now I just marched with a gown on and my bum hanging out. Like a dystopian scene.” But, Cornish says, she’s been blessed. No chemotherapy or radiation, just the op. “Cancer sucks, man, but you know what? I’m grateful it was caught soon. I underwent removal a few months back and my right breast now resembles a grapefruit under a tight bedsheet.” A further beam. “The nipple was preserved.”

The subsequent surgery is therapeutic and aesthetic. Her boobs, she notes, are now “asymmetrical. The size doesn’t match. So inconsiderate! I felt, why make it worse, I’m already having a rough time. How offensive! Amusingly I said I’d never get my boobs done because I’ve got OCD, and I know they’d never be flawless. My plans were disrupted.”

Past Medical Issues

Cornish is accustomed to medical issues. She thinks her perspective on the cancer has been so upbeat because she’s experienced in physical challenges. They have often coincided with peak moments, serving as a tap on the shoulder, or blow, to highlight not to take anything for granted. “Honestly, I feel life goes, ‘You having a good time? Take a seat.’ Since childhood, it has often paired with moments of success for me; something severe or obscure has affected my well-being.”

She reminisces to her 11-year-old self, already starting her career performing in the West End in the production (she was selected at the age of 9). That’s when she was found to have the medical problem Wolff-Parkinson-White syndrome, which can cause a tachycardia as well as vertigo and heart flutters. “I rehearsed between visits on an intravenous line, and returning to the hospital at night.” She jumps ahead half a dozen years, and teenage Jess has entered the girl group the group while studying at the Brit School. “I just got my first record deal, and I had a brain incident. Then when I was planning to release songs in 2020 I had a collision and my throat was injured and I lost my voice for a year.”

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