Surgeons at Kenyatta National Hospital (KNH) have performed what is being described as the world’s largest breast reduction surgery, successfully removing 20.86 kilograms of breast tissue from a 17-year-old girl suffering from a rare condition known as gigantomastia.
The procedure took place on September 22, 2025, and lasted approximately 11 hours. It was led by Dr. Benjamin Wabwire, Head of Specialized Surgery and Consultant Plastic and Reconstructive Surgeon at KNH, together with a multidisciplinary surgical team.
The hospital explained that the teenager’s condition caused her breasts to grow abnormally large, amounting to nearly 37% of her body weight. The excessive tissue led to back pain, difficulty breathing, and social and psychological distress.
KNH described the procedure as a major breakthrough, noting that the surgery significantly improved the patient’s quality of life.
The patient, identified in local media only as Lydia, is reported to be recovering well after the operation.
Gigantomastia is a rare condition characterized by excessive breast tissue growth that can severely affect mobility and physical comfort.
“Great job by the KNH team—very proud to see this level of expertise in Kenya.”, a comment on K24 TV post on their page.
“This gives hope to so many patients. Medical breakthroughs here matter.” – Comment on The Standard (Kenya) official page
“I can’t imagine what that young lady went through, glad she’s getting help.” a reader said under Dawan Africa news article
What Is Gigantomastia?
Gigantomastia is a rare medical condition involving excessive breast tissue growth, often without a clear cause.
It can occur during puberty, pregnancy, or in response to hormonal changes, and may cause:
- Chronic back, neck, and shoulder pain
- Postural imbalance and restricted movement
- Recurrent infections beneath the breasts
- Emotional distress and social isolation
Treatment often involves reduction mammoplasty (breast reduction surgery) to remove the excess tissue and relieve symptoms while in severe or recurring cases, long-term hormonal therapy or reconstructive surgery may be required.
