‘It has made me live life more’: Jessie J on her health battle, career returns and conquering the Chinese market

You can’t imagine it, the singer states. There she was gearing up for her comeback record in nearly a decade, ecstatically in love with her current love, and at long last the mother of a toddler after struggling to conceive for ten years, riding high. Suddenly in March she was diagnosed with breast cancer.

The singer-songwriter, real name Jessica Cornish, is famous for being brutally honest. The album, Don’t Tease Me With a Good Time, was intended as an candid account, dealing with every moment of pain she’d endured since she last recorded music (endometrial issues, losing a baby, unsuccessful partnerships, psychological manipulation, suicide) with characteristic openness. The initial release, the song No Secrets, was launched in the spring. But by then there remained a major undisclosed truth. Her diagnosis. Then next release, the upbeat Living My Best Life, came out in May and she was talking to press about how she was thriving, while all the while coping with breast cancer. 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 put out with a song called No Secrets. I’m doing every media appearance, and they’re, like, ‘Any updates?’ and I’m, like, ‘Erm, yeah, nothing …’” the singer has just had to call off performances because she’s still waiting for follow-up surgery.

We’re at a photography studio in the capital. She is dressed in a tan faux-leather coat, denim trousers with detailed white appliqués, off-white boots and oversized specs. Imagine biker chic meets vintage look. “It seems like I’m in the seventies and I should have a man with facial hair.” Like the film, I say, recalling the film. “That’s what people called me at school!” She grins. She is sharp-witted, irreverent and filter-free. She says she has always wanted to try comedy and is hoping to make her standup debut in the coming year. “I like entertaining. During performances I often tease the crowd.”

Personal Battles and News

The artist was preparing for an performance at the ceremony when she discovered a mass. “I immediately went to get it examined, had an test, and they told me, ‘It appears fine; your breasts are normal.’ And I responded, ‘However, it’s there. 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?’ It happened on March 28, the day after my birthday.” It was a Friday. The specialist told her if it was concerning she’d reach out on the Monday. By then she had assured herself it was okay. The way she explains it, it was just bad timing to receive a diagnosis when she had many commitments.

“It was a fortnight prior from releasing the album after eight years without an album and no new music. And she [the doctor] texted and said, ‘Are you free at six?’ And I thought, ‘A video call, likely minor.’ So I log in expecting it’s all going to be good, and she informs me, ‘You might want to sit.’ You know that sad tone they use? And she continues, ‘I’m so, so sorry but your test results have shown malignant cells.’” What was your reaction? “I answered, ‘Well, that’s not great. That’s not fucking great timing.’ My initial thought was, ‘I can’t die because my son needs me.’”

I’ve been labeled difficult for knowing myself

She considered the operation frightening and surreal. “I dislike anesthesia. You’re escorted. You know when you have emergency surgery you roll down in a bed, but now I just marched with a gown on and my backside out. It felt surreal.” But, she notes, she’s been lucky. Without chemo or radio, just the surgery. “Cancer is awful, but you know what? Luckily it was detected early. The surgery happened a few months back and my affected breast now looks like a odd shape.” Another grin. “At least the nipple remains.”

The subsequent surgery is therapeutic and aesthetic. Her boobs, she observes, are now “different sizes. The size doesn’t match. So inconsiderate! I thought, don’t add insult to injury, I’m already having a rough time. So rude! It’s funny because I said I’d avoid breast surgery because I’ve got obsessive tendencies, and I know they’d never be perfect. Cancer ruined that plan.”

Past Medical Issues

Cornish is no stranger to illness. She feels her perspective on the cancer has been so upbeat because she’s familiar with physical challenges. Many times they occur alongside professional successes, acting as a reminder, or shock, to highlight not to assume everything is fine. “Truly, I feel fate says, ‘You having a good time? Sit down.’ From a young age, it has always gone alongside high points for me; something severe or obscure has impacted my body.”

She takes me back to her 11-year-old self, already starting her career performing in the West End in Whistle Down the Wind (she was cast at the age of nine years old). That’s when she was diagnosed with the medical problem WPW, which can cause a fast heartbeat as well as lightheadedness and heart flutters. “I rehearsed between visits on an drip, and going back into hospital at night.” She skips forward half a dozen years, and teenage Jess has joined the girl group Soul Deep while attending 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 car crash and my larynx moved up and I lost my voice for a twelve months.”

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