In a remarkable medical milestone, a team of surgeons at Kenyatta National Hospital (KNH) has successfully performed the world’s largest recorded gigantomastia surgery, removing a staggering 20.86 kilograms of breast tissue from a 17-year-old girl.
The 11-hour procedure, carried out on September 22, 2025, marks a major breakthrough for Kenya’s top referral hospital.
A Life-Changing Operation
The patient, Lydia Musivi, had been living with gigantomastia, a rare condition causing excessive and rapid breast growth.
The weight of the tissue—equivalent to 37% of her total body weight—had left her in constant pain, unable to walk or stand upright, and forced her to drop out of school.
Now, following the surgery, Lydia says she finally feels free.
“The weight is now over. I feel lighter and ready to return to school,” she said in part of the press releease by KNH.
“I can finally live the life I was meant to live and follow my dream of becoming a high school teacher.”
A Mother’s Unwavering Faith
Lydia’s mother, Ms. Naomi Mutendwa, spoke emotionally about the long and painful journey before reaching KNH.
“I watched my daughter disappear under the weight of this illness. It stole her confidence and her future,” she recalled.
“We felt hopeless until we were referred here from Garissa County Referral Hospital. The team didn’t just treat her; they gave me back my daughter.”
A Team Effort of Global Expertise
The complex surgery was led by Dr. Benjamin Wabwire, KNH’s Head of Specialized Surgery and Consultant Plastic and Reconstructive Surgeon, who described the operation as both a scientific and emotional triumph.
“This was more than a surgical success; it was the restoration of a young woman’s dignity and future,” said Dr. Wabwire.
“Our team at KNH proved that with world-class skill and deep compassion, we can overcome even the most extreme medical challenges.”
The multidisciplinary team featured collaboration between local and international experts, including Professor Lew and Dr. Kim from Yonsei University in South Korea, alongside KNH’s Dr. Claire Odero, Dr. Agnes Wanjiru, and Dr. Joy Mwangi.
The anaesthesia team was led by Dr. Eileen Towett and Dr. Hellen Mwari, while Ms. Esther Munga and Ms. Eun Jin Chae guided the nursing unit that provided critical care throughout Lydia’s journey.
Lydia has since been discharged and is recuperating at her home in Mwingi, Kitui County. She plans to return to school in January 2026, determined to reclaim her dreams and inspire others facing similar struggles.
