扱う (atsukau) is the most general verb for 'treat' and covers handling objects, people, and situations. 見なす (minasu) is specifically for regarding or deeming, often in formal contexts. 接する (sessuru) is exclusively for interpersonal treatment and behavior.

Avoid directly translating 'treat as' into Japanese without considering the context. For example, 'I treated him to dinner' is not 'treat as' but 'treat someone to something', which is ごちそうする (gochisou suru). Also, 'treat' in the medical sense is 治療する (chiryou suru). Make sure you are using the correct Japanese verb for the intended meaning.
