A cell analyzing apparatus (1) includes: a first histogram acquiring section (11) 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 (12) 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 (14) 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 (15) which is configured to output a result of the determination performed by the determining section.
