Kenyan Surgeons Remove 20.86 kg from Teen’s Breasts

By Kimberly Kalusi

In a historic and deeply transformative operation at Nairobi’s Kenyatta National Hospital (KNH), a 17-year-old Kenyan girl has undergone what is believed to be the world’s largest breast reduction surgery after living nearly two years under the physical and psychological weight of a rare condition.

The patient, identified as Lydia Musivi from Kitui County, had suffered from rapidly progressing bilateral gigantomastia — an extreme form of breast hypertrophy. Over approximately 18 months, her breasts grew so large they severely hindered mobility, caused chronic pain, and forced her out of school. According to hospital officials, the surgical team removed 20.86 kg of breast tissue during an intensive 11-hour procedure on 22 September 2025 — equaling nearly 37 % of her body weight at the time.

“For the first time in many months I could breathe without pain in my chest and carry a backpack like my schoolmates,” Lydia reflected tearfully after being discharged.

“This surgery has given me back my life — I can dream again.”

A Heavy Burden

Lydia began noticing rapid breast growth when she was around 15 years old. By the time her family sought specialist help, she was unable to walk more than a few metres or find clothing and undergarments that fit. The weight placed enormous strain on her back and neck, while the sheer volume of tissue subjected her to recurrent skin infections and emotional isolation.

Her mother, Naomi Mutendwa, said they had endured months of frustration and anxiety:

“She became a shadow of the confident girl she once was. I watched her shrink inside because of pain no one could see.”

After referral from a county hospital, Lydia was accepted for treatment at Kenyatta National Hospital, where a multidisciplinary team was assembled to manage what is arguably one of the most extreme cases worldwide.

Surgical Milestone

Led by consultant plastic and reconstructive surgeon Dr Benjamin Wabwire, the team included specialists in anaesthesia, paediatric surgery, nursing and rehabilitation. The procedure involved advanced reduction-mammoplasty techniques together with expert post-operative care.

“This was more than a medical success — it was the restoration of a young woman’s dignity, her childhood and the promise of a future,” Dr Wabwire said.

After the tissue removal, Lydia’s posture improved markedly and she regained mobility. She is now preparing to re‐enrol in school at the start of the next term.

Beyond the Operating Table

Gigantomastia is exceptionally rare, with literature noting only a limited number of cases globally. It presents not only physical but profound emotional and social burdens. According to a 2023 review, adolescent breast hypertrophy often triggers anxiety, depression and social withdrawal in young girls. ResearchGate+2PMC+2

The surgery at KNH highlights the strides Kenyan healthcare is making in advanced reconstructive services. “We are proving that world-class breakthroughs can and do happen here,” expressed the hospital’s acting CEO.

A New Chapter

Lydia’s aspirations are no longer confined by her physical limitations. She has expressed her dream of becoming a high school teacher and hopes to advocate for others facing similar health challenges.

“I want other girls to know they don’t have to live in silence,” Lydia said.

Her story has already drawn attention from international health communities and carries potential to attract global NGOs, philanthropic donors and medical technology sponsors — enhancing visibility for both the hospital and the broader campaign for adolescent girls’ health rights.

Message of Hope and Awareness

Beyond this remarkable surgical milestone lies a broader conversation: the need for awareness of rare conditions, timely referrals, mental health support and access to specialised surgery. Lydia’s journey — from limitation to liberation — offers a compelling human-interest narrative that resonates far beyond the confines of one operating theatre.

As she takes her first steps into a freer, healthier tomorrow, Lydia is not just recovering; she is reclaiming the destiny that gigantomastia tried to steal. Her story stands as a testament to resilience, medical innovation and the power of hope.
