Libby Pearson from Kent underwent preventative double mastectomy after discovering BRCA1 gene mutation gave her over 80% breast cancer risk, sharing her journey on TikTok
At merely 25 years of age, most women are preoccupied with their social calendars, organising weekend getaways, or advancing their professional lives. However, for Libby Pearson from Kent, the choice she confronted was far more terrifying: have both breasts surgically removed immediately, or gamble with cancer potentially claiming them, and conceivably her life, at a later stage.
“It felt like my breasts were ticking time bombs,” she says. “I didn’t want to sit and wait to get cancer. I wanted to stop it before it even had a chance.”
Libby, who is employed by an enforcement agency handling outstanding council tax and business rates, is accustomed to managing high-pressure circumstances.
Yet nothing could have equipped her for discovering she carried the BRCA1 genetic mutation, the identical one that prompted Angelina Jolie to undergo preventative surgery.
“Hearing the word BRCA changes your whole future in a second,” she explains. “Suddenly your life becomes measured in risks and percentages instead of hopes and plans.”
The cancer history within Libby’s family is heartbreaking. She was merely 19 when blood tests disclosed she had inherited the gene from her mum, Julie, who had fought and conquered triple negative breast cancer following gruelling chemotherapy.
“I remember thinking, why do I have to deal with this when I’m still a teenager?” she says. “TikTok wasn’t really around back then, so I had no one my age to relate to. I felt completely alone.”
Medical professionals informed her they would make contact again when she reached 25, the age when preventative measures could finally be presented. True to their word, in April 2025, her phone r ang.
She received an invitation to meet with a specialist breast team at Guy’s and St Thomas’ in London. They outlined that with BRCA1, her likelihood of developing breast cancer exceeded 80%. Through a single procedure, a preventative double mastectomy, her risk could plummet to below 10%.
“I always imagined walking down the aisle one day looking like me. I imagined being able to breastfeed my children,” she says quietly. “But that day, I had to let go of that version of the future.”
The instant it became reality is a memory that will stay with her forever. “My surgeon turned around to me and said, ‘We could fit you in in two weeks,’ and I just froze,” she recalls. “I thought I’d have months to mentally prepare. Instead, everything suddenly sped up.”
Her stomach plummeted. Her heart raced. Yet she glanced at her mum, the woman who had beaten cancer, and gave a nod. “I thought: I’m not letting cancer take its turn. I’ll take mine first.”
On August 12th, 2025, she entered hospital knowing she would depart without the breasts she had grown up with. She opted for implants, as she lacked sufficient body tissue for natural reconstruction.
“Everyone online has their own opinion about implants,” she explains. “But my surgeon told me I can always revisit reconstruction after kids if I want to. This is what worked for me, for right now.”
Upon awakening, the reality struck forcefully. “I opened my eyes in recovery and felt so vulnerable,” she remembers. “I was confused from the anaesthesia and just cried asking for my mum. Nothing prepares you for that moment.”
The initial moment she glimpsed herself proved even more challenging. “I hated what I saw. I took the surgical bra off and just sobbed,” she says. “It didn’t feel like my body anymore.”
Whilst her scars mended physically, the emotional healing required far more time. “Everyone around me went back to work and normality,” she explains. “But for me, life wasn’t normal anymore. My mind hadn’t caught up with what happened to my body.”
Three weeks post-operation, she reached what she describes as her “lowest point. “Everything hit me all at once, I couldn’t run yet, I’d lost something so personal, and breastfeeding had been stripped away from me as an option,” she says.
“I was angry at the gene. I asked myself, why me?”. Yet slowly she discovered strength in her choice, along with newfound confidence that emerged. “Now, when I look at myself, I feel powerful. I feel brave. I feel like I beat cancer before it could even try,” she says proudly.
Fresh from major surgery, Libby grabbed her phone whilst lying in her hospital bed and filmed a TikTok. “I wanted to show people that the first night doesn’t have to be scary,” she says. “I lay there alone and thought: wow, look what I just did. Look what I survived.”
The clip became a sensation, with messages flooding in from young women confronting exactly what she had endured at 19: terror, bewilderment, loneliness. “So many of us are out there, but we don’t realise it because no one talks about it,” she explains.
Remarks such as “aren’t you too young for this?” continue to irritate her. “Cancer doesn’t check your age before attacking,” she retorts. “We shouldn’t have to defend saving our own lives.”
Resolved that no other young woman should experience the isolation she once knew, Libby teamed up with fellow BRCA1 fighter Charlotte Harmer, and together they created an Instagram support network where women can link up, share their experiences and discover genuine empathy.
“We wanted a safe space where BRCA girlies can talk honestly,” she explains. “Somewhere to say the things you can’t even say to doctors.”
