Hello doctors I just want to ask. Ihave a cyst on my face behind my right eye. It's color is bluish green and encapsulated and movable. Is it cancerous?

Cyst on Face. Most encapsulated cysts are not cancerous. They can be removed with a minor surgical procedure: the wall of the cyst usually also needs to be removed to prevent the cyst from returning.
Maybe. See an ophthalmologist for complete evaluation.
