user-story

While the core of requirements development and acceptance criteria would ideally take place during the planning meeting in order to create a better estimate, Scrum encourages continuous interaction with the product owner throughout the sprint to validate and refine user stories.

What kind of criteria is used to judge if there is too much change being imposed on a user story mid-sprint?
When is it appropriate to change the requirements of the user story?
When is it appropriate to cancel the user story / sprint in order to re-evaluate and re-estimate a user story in question?
