‘It has made me live life more’: Jessie J on cancer, career returns and cracking China

You wouldn’t believe it, Jessie J says. There she was gearing up for her comeback record in eight years, deeply enamored with her recent boyfriend, and at long last the parent to a young child after dealing with conception issues for ten years, riding high. Suddenly in spring she was found to have a breast cancer diagnosis.

The artist, birth name Jess Cornish, is renowned for telling it as it is. The record, the provocatively titled album, was supposed to be an candid account, addressing every bit of hardship she’d faced since she last worked on songs (endometriosis, pregnancy loss, unsuccessful partnerships, gaslighting, suicide) with characteristic openness. The first single, her single No Secrets, was released in the spring. But by then there was a mighty secret. The illness. Then follow-up track, Living My Best Life, debuted in May and the artist was speaking publicly about how she was enjoying life to the fullest, while at the same time coping with the disease. A month later she shared the news, and in early July she had a mastectomy.

She offers me her best “Are you kidding?” expression. “I come out with a song called the track No Secrets. I’m conducting every media appearance, and they’re, like, ‘What’s happening?’ and I’m, like, ‘Erm, yeah, nothing …’” Cornish has just had to call off performances because she’s still waiting for reconstructive surgery.

We meet at a photo studio in the capital. She is wearing a beige fake-leather jacket, jeans with ornate white designs, cream boots and oversized specs. Imagine motorcycle style meets 70s singer aesthetic. “As if I’m in the 70s and I should have a partner with a mustache.” Like the film, I say, referencing the film. “That’s what people called me at school!” She grins. Cornish is quick, irreverent and filter-free. She says she has always been interested in humor and is planning to attempt her standup debut in the coming year. “I enjoy humor. During performances I basically roast the crowd.”

Health Struggles and Diagnosis

The artist was planning an performance at the awards show when she noticed an abnormality. “I promptly visited to get it checked, had an scan, and they were, like, ‘It looks like nothing; you’ve got really good dense breast tissue.’ And I insisted, ‘However, it’s there. I have arm pain and tingling in my hands whenever I rise.’ And they replied, ‘Well, let’s just do a biopsy?’ It happened on March 28, the following my birthday.” It was a Friday. The doctor told her if it was concerning she’d reach out on the start of the week. By then Cornish had persuaded herself it was okay. The way she tells it, it was inopportune to receive a diagnosis when she had so much on.

“It was a fortnight prior from launching this thing after eight years without an album and no new music. And the doctor messaged 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 fine, and she informs me, ‘Please take a seat.’ You know that sad tone they use? And she continues, ‘Unfortunately but your biopsy results have shown high-grade cancer cells.’” What was your reaction? “I said, ‘Well, that’s not great. The timing is terrible.’ The first thing I thought was, ‘My child depends on me.’”

Some men find me challenging due to my self-awareness

She considered the operation terrifying and absurd. “I fear going under. They walk you down. In urgent cases you are wheeled, but this time I just strolled down with a gown on 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 surgery. “It’s terrible, but yet I’m grateful it was caught soon. I had the mastectomy recently and my right breast now looks like a grapefruit under a tight bedsheet.” A further beam. “At least the nipple remains.”

The next operation is for health and appearance. Her boobs, she notes, are now “different sizes. The size doesn’t match. So inconsiderate! I reflected, don’t add insult to injury, I’m already having a rough time. Such disrespect! Amusingly I said I’d not undergo augmentation because I’ve got obsessive tendencies, and I know they’d never be perfect. Cancer ruined that plan.”

Past Medical Issues

She is no stranger to illness. She believes her perspective on the cancer has been so positive because she’s familiar with health crises. Many times they occur alongside career highs, serving as a tap on the shoulder, or blow, to remind her not to be complacent. “Truly, I feel fate says, ‘Things going well? Hold on.’ Ever since I was a child, it has often paired with high points for me; something severe or obscure has happened to my health.”

She reminisces to her childhood, already beginning starring in the stage in a musical (she was selected at the age of nine). That’s when she was diagnosed with the cardiac issue a syndrome, which can cause a rapid pulse as well as dizziness and heart flutters. “I attended rehearsals intermittently on an intravenous line, and returning to the hospital at night.” She skips forward half a dozen years, and 17-year-old Jess has become part of the trio the group while studying at the performing arts school. “I secured a deal, and I had a stroke. Then when I was planning to release songs in 2020 I had a automobile accident and my larynx moved up and I lost my voice for a twelve months.”

Hey, I say, wait, I am overwhelmed. At just 17? She nods|agrees
