Lymphoedema: A silent burden for cancer survivors
For millions worldwide, surviving cancer comes at a hidden cost: a painful, incurable condition called lymphoedema. Despite affecting an estimated 250 million people globally, the disease remains underdiagnosed, underfunded, and largely ignored by healthcare systems.
What is lymphoedema?
Lymphoedema is a chronic condition causing severe swelling due to a damaged lymphatic system, which regulates fluid balance and immune function. When lymph fluid fails to drain properly, tissues swell, often leading to pain, mobility loss, and recurrent infections. The lymphatic system-a network of vessels and glands-plays a crucial role in waste removal and disease defense, yet its dysfunction is linked to conditions like cancer, heart failure, and Alzheimer's.
"The lymphatic system permeates every organ and tissue, but we can't see it until it stops working," says Kimberley Steele, a former surgeon at Johns Hopkins University and program manager at ARPA-H.

A common yet neglected consequence of cancer
Cancer treatments like surgery and radiotherapy frequently damage or remove lymph nodes, triggering lymphoedema. One in five breast cancer survivors develops the condition, while up to 90% of head and neck cancer patients face it. Yet, as one oncologist bluntly told a patient's family, "There's nothing we can do."
Matt Hazledine, founder of Lymphoedema United, describes his diagnosis after a severe cellulitis infection as "life-changing." His leg swelled to 60% larger than normal, gaining 8kg (17.6lbs) in weight. "At 40, it was devastating," he says. Like many, he struggled to find information or support.
The human and financial toll
Lymphoedema's impact extends beyond physical pain. Patients face depression, lost productivity, and financial strain. In the UK, the NHS spends £178 million ($225 million) annually on hospital admissions for complications like cellulitis, while U.S. patients incur $270 million (£213 million) in hospital charges. Yet, proper treatment could reduce complications by 94% and hospital admissions by 87%.
Didi Okoh, a 2024 Paralympic bronze medalist, nearly died from cellulitis after emergency doctors ignored her symptoms for hours. "Every infection damages my leg further," she says. "It resets to a bigger size, and I can't shrink it back."
A crisis of awareness and care
Medical education dedicates less than 25 minutes to the lymphatic system, leaving most doctors unprepared to diagnose or treat lymphoedema. In the UK, only five specialists serve the entire country, forcing patients to travel vast distances for care. Amy Rivera, diagnosed with Milroy's disease after 32 years of misdiagnosis, was told by a doctor, "You'll be in a wheelchair by 35. Enjoy life now."
Rivera now runs a charity and a company providing lymphoedema training. "It's not just swelling-it's debilitating," she says. "I spend six to seven hours daily managing it."
Breaking the silence
Advocates like Hazledine and Rivera are pushing for change. Studies show early intervention can help patients "live well" with lymphoedema, but access to care remains a postcode lottery. In the U.S., insurance often fails to cover treatments, while UK services are being cut.
"We're 100 years behind in research," says Kristiana Gordon, a lymphoedema specialist at St George's University Hospital. "Even if students don't specialize, they should at least recognize the condition."

Hope on the horizon
Researchers like Katherine Wang, inspired by her uncle's struggle, are developing wearable devices to help patients self-manage symptoms. Meanwhile, organizations like the Lymphoedema Support Network and Ninjas Fighting Lymphedema Foundation offer resources and community.
"You're not alone," Hazledine says. "With the right support, you can thrive."
