‘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. At that moment gearing up for her first album release in eight years, blissfully happy with her recent boyfriend, and finally the mom to a little one after struggling to conceive for ten years, feeling invincible. Then in March she was diagnosed with a breast cancer diagnosis.

The artist, birth name Jess Cornish, is known for telling it as it is. The album, her latest release, was supposed to be an candid account, dealing with every moment of pain she’d faced since she last made an album (a gynecological condition, pregnancy loss, failed relationships, emotional abuse, mental health struggles) with her usual frankness. The first single, her single No Secrets, was released in the spring. But by then there was a mighty secret. The cancer. Later second single, Living My Best Life, debuted in late spring and she was giving interviews about how she was thriving, while all the while dealing with breast cancer. A month later she disclosed her condition, and in early July she underwent breast removal surgery.

She offers me her best “What the fuck?” look. “I release with a song called the track No Secrets. I’m conducting every interview, and they inquire, ‘What’s happening?’ and I’m, like, ‘Uh, nothing really’” she has just had to call off performances because she’s awaiting cosmetic procedures.

Our interview takes place at a studio in London. She is dressed in a light brown synthetic jacket, blue jeans with elaborate white patches, off-white boots and large glasses. Picture biker chic meets 1970s Nana Mouskouri. “I feel like I’m in the seventies and I should have a man with facial hair.” A biker reference, I say, referencing the picture. “They used to call me that!” She beams. Cornish is fast-thinking, bold and direct. She says she has always been interested in humor and is planning to attempt her standup debut in the coming year. “I enjoy humor. On stage I often tease the crowd.”

Medical Challenges and Discovery

The artist was preparing for an slot at the ceremony when she discovered a mass. “I immediately went to get it looked at, had an ultrasound, and they were, like, ‘It looks like nothing; your breasts are normal.’ And I insisted, ‘However, it’s there. I’ve got an achy arm and tingling in my hands whenever I wake up.’ And they replied, ‘Well, let’s just do a biopsy?’ It happened on March 28, the post-birthday.” It was a weekend eve. The doctor told her if it was bad news she’d call on the Monday. By then Cornish had convinced herself it was okay. The way she describes it, it was just bad timing to face illness when she had many commitments.

“Just two weeks before from launching this thing after years away and an extended break. And the doctor messaged and said, ‘Are you free at six?’ And I assumed, ‘It’s virtual, probably routine.’ So I log in expecting it’s all going to be positive, and she informs me, ‘Are you sitting down?.’ You know that sad tone they use? And she reveals, ‘I regret to inform you but your test results have indicated aggressive cancer.’” What did you say? “I replied, ‘That’s unfortunate. What awful timing.’ Immediately I felt was, ‘I have to survive for my boy.’”

Some men find me challenging due to my self-awareness

She found the surgery frightening and surreal. “I fear going under. They walk you down. In urgent cases you go on a gurney, but now I just marched with a medical attire and my backside out. You feel like you’re in an episode of Black Mirror.” But, she adds, she’s been lucky. No chemo, no radiotherapy, just the procedure. “Cancer sucks, man, but yet I’m grateful it was caught soon. I had the mastectomy four months ago and my one side now appears as a fruit under fabric.” A further beam. “The nipple was preserved.”

The follow-up procedure is for health and appearance. Her boobs, she observes, are now “uneven. They didn’t do an implant as small as my original. How rude! I felt, no need to bully me, I’m already having a difficult experience. Such disrespect! Ironically I said I’d never get my boobs done because I’ve got perfectionism, and I know they’d never be ideal. Illness changed that.”

Past Medical Issues

She is accustomed to medical issues. She thinks her perspective on the cancer has been so positive because she’s experienced in physical challenges. Frequently they align with professional successes, functioning as a wake-up call, or shock, to highlight not to be complacent. “Honestly, I feel life goes, ‘You having a good time? Hold on.’ From a young age, it has often paired with achievements for me; a major or strange event has impacted my body.”

She reminisces to her 11-year-old self, already starting her career featuring in the London theater in a musical (she was selected at the age of nine years old). That’s when she was diagnosed with the heart condition WPW, which can cause a rapid pulse as well as dizziness and heart flutters. “I was going in and out of rehearsals on an IV drip, and returning to the hospital at night.” She fast-forwards several years, and 17-year-old Jess has joined the trio Soul Deep 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 recently I had a automobile accident and my voice box shifted and I was unable to vocalize for a twelve months.”

Wow, I say, wait, I can’t keep up. At just 17? She nods|agrees
