Jessie J has revealed she was diagnosed with breast cancer in March after finding a lump and pushing for further tests.
The British singer said the moment she received the results was a shock that immediately made her think of her young son.
In an interview with The Guardian, the 36-year-old explained she first went for an ultrasound and was told it “looked like nothing.”
Despite that reassurance, she said something felt wrong and she insisted on having a biopsy.
Jessie, whose real name is Jessica Cornish, said the biopsy took place on March 28, the day after her birthday.
She was told she would only receive a call on Monday if the news was bad.
Convinced everything would be fine, she joined what she thought was a routine video call.
Instead, she was asked if she was sitting down.
‘High-Grade Cancer Cells’ and a Mother’s First Thought
During the interview, Cornish said doctors told her the results showed “high-grade cancer cells.”
Her immediate reaction was practical rather than emotional.
“The first thing I thought was, ‘I can’t die because my son needs me,’” she said.
The singer, known for hits including Price Tag and Domino, has since spoken openly about surgery and treatment.
She has also described the emotional strain of balancing motherhood with a cancer diagnosis.
In comments reported by The Independent, she said it felt impossible to be fully present as a parent.
“It feels like I can’t be a mum. I can’t be present. I’m being robbed of all these memories,” she said.
Jessie is the mother of a toddler after years of trying to conceive.
She said becoming a parent has completely changed how she views illness and recovery.
Diagnosis Collided With Long-Awaited Musical Comeback
Jessie explained that her diagnosis came as she prepared to release her first album in eight years.
By the time she began promoting new music publicly, she said she was living with a “mighty secret.”
Her single No Secrets was released in April, just weeks after her diagnosis.
She continued doing interviews while keeping her health news private.
“I’m doing every interview, and they’re like, ‘So what’s new with you?’ and I’m like, ‘Erm, yeah, nothing,’” she recalled.
She went public with her diagnosis a month later.
Jessie then underwent a mastectomy in early July.
She described the lead-up to surgery as “terrifying and absurd.”
She said she hated being put under anaesthetic and remembered being walked to theatre in a gown.
Treatment, Recovery, and Looking Ahead
Jessie said she felt fortunate compared to others facing cancer.
“No chemo, no radiotherapy, just the op,” she told The Guardian.
She added that doctors found the cancer early.
“Cancer sucks, man, but thank f*** I found it early,” she said.
She is now waiting for reconstructive surgery and has cancelled tour dates while recovering.
Jessie also reflected on her long history of health issues.
She was diagnosed with Wolff-Parkinson-White syndrome as a child and suffered a stroke at 17.
She said major illnesses often appeared during key moments in her career.
Those experiences, she believes, shaped how she responded to her cancer diagnosis.
Her parents, she said, taught her not to let illness define her life.
“That approach has stayed with me into adulthood,” she explained.
Jessie’s account frames her diagnosis not as a celebrity headline, but as a deeply personal interruption.
It is a story of treatment, motherhood, and reassessing what truly matters while moving forward.
