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

You can’t imagine it, Jessie J says. There she was gearing up for her comeback record in eight years, deeply enamored with her newish partner, and finally the mom to a little one after dealing with conception issues for ten years, feeling invincible. Then in March she was diagnosed with breast cancer.

The singer-songwriter, real name J. Cornish, is known for telling it as it is. The album, Don’t Tease Me With a Good Time, was intended as an transparent story, tackling every ounce of devastation she’d endured since she last recorded music (endometrial issues, pregnancy loss, failed relationships, emotional abuse, mental health struggles) with characteristic openness. The initial release, her single No Secrets, was launched in the spring. But by then there existed a huge secret. The illness. Later second single, her song Living My Best Life, debuted in May and Cornish was speaking publicly about how she was thriving, while at the same time living with her cancer. Four weeks after she shared the news, and in early July she had a mastectomy.

She gives me her best “Are you kidding?” look. “I come out with a song called No Secrets. I’m doing every interview, and they’re, like, ‘So what’s new with you?’ and I answer, ‘Uh, nothing really’” Cornish has just had to cancel tour dates because she’s awaiting cosmetic procedures.

We meet at a studio in London. She is wearing a beige fake-leather jacket, denim trousers with ornate white designs, cream boots and big frames. Think rocker vibe meets 70s singer aesthetic. “I feel like I’m in the seventies and I should have a boyfriend with a big tache.” A biker reference, I say, referencing the film. “I was nicknamed that in school!” She grins. Cornish is fast-thinking, irreverent and direct. She says she has always fancied doing comedy and is hoping to make her initial standup show in the coming year. “I love making people laugh. When performing I basically roast the audience.”

Personal Battles and News

The artist was preparing for an performance at the awards show when she discovered a mass. “I promptly visited to get it examined, had an ultrasound, and they said, ‘It seems benign; you’ve got really good dense breast tissue.’ And I insisted, ‘However, it’s there. My arm hurts and numbness in my fingers whenever I wake up.’ And they said, ‘Well, let’s just do a biopsy?’ The date was March 28, the day after my birthday.” It was a Friday. The specialist told her if it was bad news she’d reach out on the start of the week. By then she had persuaded herself it was fine. The way she tells it, it was just bad timing to face illness when she had so much on.

“We’re two weeks away from launching this thing after a long hiatus and an extended break. And the doctor messaged and said, ‘Can you talk at six?’ And I thought, ‘It’s virtual, probably routine.’ So I log in thinking it’s all going to be fine, and she goes, ‘Please take a seat.’ That sympathetic voice? And she says, ‘I regret to inform you but your test results have shown aggressive cancer.’” How did you respond? “I answered, ‘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 scary and bizarre. “I fear going under. They lead you. During crises you are wheeled, but this time I just marched with a gown on and my rear exposed. Like a dystopian scene.” But, Cornish says, she’s been blessed. Without chemo or radio, just the procedure. “Cancer is awful, but however Thank fuck I found it early. I underwent removal recently and my one side now appears as a grapefruit under a tight bedsheet.” Another grin. “At least the nipple remains.”

The follow-up procedure is for health and appearance. Her chest, she remarks, are now “different sizes. The implant is larger than before. So inconsiderate! I reflected, 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 perfectionism, and I know they’d never be perfect. My plans were disrupted.”

Previous Struggles

The singer is familiar with health problems. She feels her outlook on her diagnosis has been so positive because she’s experienced in medical emergencies. Many times they occur alongside professional successes, serving as a tap on the shoulder, or punch in the stomach, to highlight not to take anything for granted. “Truly, I feel the universe whispers, ‘Things going well? Sit down.’ Ever since I was a child, it has often paired with high points for me; a serious or unusual issue has happened to my health.”

She recalls to her childhood, already starting her career starring in the stage in a musical (she was selected at the age of nine years old). That’s when she was told about the cardiac issue Wolff-Parkinson-White syndrome, which can cause a fast heartbeat as well as dizziness and irregular beats. “I attended rehearsals intermittently on an drip, and returning to the hospital at night.” She fast-forwards half a dozen years, and young Jessica has joined the trio Soul Deep while studying at the academy. “I just got my first record deal, and I had a stroke. Then when I was planning to release songs in 2020 I had a automobile accident and my voice box shifted and I lost my voice for a year.”

Hey, I say, slow down, I can’t keep up. A stroke so young? She nods|agrees
