Mr Leo Cheng volunteers as a maxillofacial and head and neck surgeon
Professionals considering volunteering ask one question first: are the standards real?
Volunteering is not a lowering of standards. A surgeon's registration, indemnity and professional judgement travel with them.
A consultant who kept coming back
Mr Leo Cheng is a consultant maxillofacial and head and neck surgeon in the United Kingdom who has volunteered with Mercy Ships across multiple field services.
The cases he operates on aboard ship are among the largest facial tumours a surgeon will encounter anywhere, precisely because they have been growing untreated for years.
Writing about it professionally
He has also written about hospital ship surgery for a clinical audience, in the medical literature rather than in fundraising material.
That distinction matters. Professional volunteers are persuaded by peer-reviewed description of what the work involves, not by inspirational language.
What a surgeon should expect on board
Purpose-built operating rooms, a specialist anaesthetic team, a blood bank supplied by the crew themselves, sterile processing, intensive nursing and structured follow-up. The constraints are real, but they are the constraints of a functioning surgical hospital.
