Cervical cancer is cancer that starts in the cervix. The cervix is the lower part of the uterus (womb) that opens at the top of the vagina. Worldwide, cervical cancer is the third most common type of cancer in women. It is much less common in the United States because of the routine use of Pap smears. Cervical cancer starts in the cells on the surface of the cervix. There are 2 types of cells on the surface of the cervix, squamous and columnar.
A balk is an illegal act by the pitcher when one or more runners are on base. The rule is in place to prevent a pitcher from deceiving the baserunners. When a balk is called, the ball is dead and all runners move up one base.
Most infractions punished as a balk: the ball is dead, no change made to the count on the batter and all runners on base advance. With no runners on base, for some infractions, the pitch attempt is automatically a ball.
