Jessie J made an announcement in 2025 that would shock the world.
In June 2025, the singer and songwriter publicly announced that she had been diagnosed with early-stage breast cancer, sharing the news directly with fans on social media and emphasizing the importance of early detection.
When she first announced her cancer diagnosis, Jessie said she wanted to “be open and share it” with her fans.
“First, because I selfishly don’t talk about it enough,” she said at the time, adding: “I don’t deal with it because I work so hard. I also know how much sharing in the past has helped me with other people giving me their love and support, as well as their own stories.”
She said she had been “in and out of tests” before the diagnosis and planned to take a break from music after a big performance that month to focus on treatment.
Surgery and early treatment:
After announcing her diagnosis, Jessie J underwent surgery and a mastectomy as part of her treatment. She documented the experience with candid updates, showing both the emotional lows and the supportive moments with her partner and young son.
Emotional highs and lows:
Throughout the process, Jessie has been quite active on her social media platforms and has been honest about how the trip has affected her emotionally.
She shared times when she felt overwhelmed and “very low,” especially when she paused from work and allowed herself to process the experience. At the same time, she has spoken about moments of gratitude and resilience.
Ongoing challenges:
Post-surgery recovery is also difficult in itself, as some reports say Jessie J faced additional health issues months after her initial procedure, such as unexpected hospital visits and complications, illustrating the physical and emotional complexity of the healing process.
Public advocacy and support:
Jessie J has been open about her diagnosis and treatment, not only for herself, but also to support others dealing with similar health issues. Her willingness to share both the struggles and progress was encouraged by fans and fellow artists alike.
