Start here: skin cancer reconstruction is almost always funded
Before any conversation about private cost, it is worth confirming what your own health system already provides, since skin cancer reconstruction, as treatment of cancer rather than elective cosmetic surgery, is almost always funded as part of the same service that manages the excision itself.
This integration matters specifically here: a funded dermatology or skin cancer service typically delivers the excision, the margin confirmation, the reconstruction and the ongoing surveillance all within the same coordinated pathway. That combination is difficult to replicate through a privately arranged, one-off international trip, which is the honest basis for this page's caution about the combined package.
