vähki

Could you clarify what you mean by "vähki"? The term isn’t widely recognized in a single, standard sense. It could refer to:

- A medical term in another language (for example, related to cancer in Estonian, where the root vähi means cancer),

- A proper noun (a surname or place name in Finland or another locale),

- A fictional or project-specific concept.

If you specify the intended meaning or context, I can write a concise, neutral wiki-style article (under 300 words) accordingly.
