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.
A balk in baseball is any action by the pitcher that violates the balk rule, which restricts the actions of the pitcher when there is at least one runner on base. The purpose of the balk rule is to protect the runner or runners from being deceived by the pitcher.
The penalty for a balk is that all base runners are awarded one base. The penalty for an illegal pitch is awarding one ball to the batter (unless the batter reaches first base safely on the pitch by any means). A balk is a delayed dead ball. When you call a balk, verbalize it loudly.
