A cell analyzing apparatus includes: a first histogram acquiring section which is configured to acquire a first histogram of fluorescence intensities by using a result of a measurement of a number of nuclear stained cells； a second histogram acquiring section which is configured to acquire a second histogram that is normalized based on a fluorescence intensity value indicating a maximum value of the first histogram； a determining section which is configured to determine whether cancer cells exist or not, based on one of the first histogram and the second histogram； and an outputting section which is configured to output a result of the determination performed by the determining section.
