Cervical cancer is caused by severe abnormal changes in the cells of the cervix. Most precancerous or cancerous cell changes occur in the cervix at the transformation zone, because these cells normally undergo constant change.
In baseball, a balk is called by an umpire. Balk rules protect runners from being deceived by the pitcher. If the ball is thrown before the batter gets settled in the batter's box, the umpire will call a balk. If a pitcher begins his delivery motion but then stops, he'll be called for a balk.
