‘It has taught me to embrace life more’: Jessica Cornish on her health battle, comebacks and cracking China

You can’t imagine it, Jessie J remarks. There she was preparing for her comeback record in eight years, blissfully happy with her recent boyfriend, and at long last the mother of a toddler after struggling to conceive for a decade, feeling invincible. Then in spring she was told she had a breast cancer diagnosis.

The musician, birth name Jessica Cornish, is famous for being brutally honest. The record, Don’t Tease Me With a Good Time, was meant as an candid account, addressing every ounce of devastation she’d experienced since she last worked on songs (endometrial issues, losing a baby, failed relationships, gaslighting, suicidal thoughts) with her usual frankness. The lead track, her single No Secrets, was released in the spring. But by then there remained a major undisclosed truth. The cancer. Later next release, her song Living My Best Life, debuted in late spring and the artist was talking to press about how she was thriving, while all the while dealing with her cancer. Four weeks after she went public, and in July she received surgical treatment.

She shoots me her best “Seriously?” expression. “I release with a song called No Secrets. I’m conducting every interview, and they’re, like, ‘What’s happening?’ and I’m, like, ‘Uh, nothing really’” she has just had to cancel tour dates because she’s still waiting for follow-up surgery.

We’re at a photo studio in the capital. She is sporting a tan faux-leather coat, blue jeans with elaborate white patches, cream boots and big frames. Imagine biker chic meets 1970s Nana Mouskouri. “It seems like I’m in the 1970s and I should have a man with facial hair.” A biker reference, I say, thinking of the movie. “I was nicknamed that in school!” She beams. Cornish is quick, unfiltered and blunt. She says she has always fancied doing comedy and is planning to attempt her first comedy performance next year. “I like entertaining. During performances I frequently joke about the fans.”

Medical Challenges and Discovery

The artist was getting ready for an appearance at the awards show when she found a lump. “I quickly sought to get it looked at, had an test, and they said, ‘It looks like nothing; your tissue is healthy.’ And I responded, ‘However, it’s there. I’ve got an achy arm and tingling in my hands whenever I wake up.’ And they suggested, ‘How about a biopsy?’ The date was March 28, the post-birthday.” It was a weekend eve. The doctor told her if it was concerning she’d call on the Monday. By then Cornish had persuaded herself it was nothing. The way she explains it, it was just bad timing to get cancer when she had a busy schedule.

“We’re two weeks away from launching this thing after years away and four years without a single. And she [the doctor] texted and said, ‘Can you talk at six?’ And I was, like, ‘A video call, likely minor.’ So I jump on the Zoom expecting it’s all going to be fine, and she goes, ‘Are you sitting down?.’ The solemn tone? And she reveals, ‘I regret to inform you but your reports have indicated malignant cells.’” What did you say? “I answered, ‘Well, that’s not great. The timing is terrible.’ My initial thought was, ‘I can’t die because my son needs me.’”

Some men find me challenging due to my self-awareness

She viewed the procedure frightening and surreal. “I hate being put under. They walk you down. In urgent cases you are wheeled, but now I just walked with a medical attire and my rear exposed. It felt surreal.” But, she adds, she’s been blessed. No chemotherapy or radiation, just the procedure. “Cancer is awful, but yet I’m grateful it was caught soon. I had the mastectomy a few months back and my one side now appears as a odd shape.” A further beam. “I got to keep the nipple, though.”

The subsequent surgery is therapeutic and aesthetic. Her chest, she notes, are now “asymmetrical. They didn’t do an implant as small as my original. So inconsiderate! I reflected, no need to bully me, I’m already having a rough time. How offensive! Ironically I said I’d never get my boobs done because I’ve got obsessive tendencies, and I know they’d never be flawless. Cancer ruined that plan.”

A History of Health Challenges

She is no stranger to illness. She thinks her perspective on the cancer has been so upbeat because she’s used to health crises. They have often coincided with career highs, serving as a tap on the shoulder, or punch in the stomach, to make her recall not to assume everything is fine. “Honestly, I feel the universe whispers, ‘Enjoying yourself? Take a seat.’ From a young age, it has often paired with high points for me; a major or strange event has impacted my body.”

She recalls to her youth, already starting her career performing in the stage in Whistle Down the Wind (she was cast at the age of nine). That’s when she was diagnosed with the cardiac issue WPW, which can cause a tachycardia as well as vertigo and irregular beats. “I rehearsed between visits on an IV drip, and returning to the hospital at night.” She jumps ahead six years, and young Jessica has joined the girl group the group while attending the performing arts school. “I just got my first record deal, and I had a stroke. Then when I was ready to debut in recently I had a automobile accident and my voice box shifted and I lost my voice for a year.”

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