Abstract
Cervical cells can be sampled in such a way as to retain the spatial relationships that existed between the cells prior to sampling. The cells can be collected by using a cervical cell collector that samples a cervix in a spatially resolved manner. The cervix is sampled by placing a sampling balloon in position adjacent to a cervix and inflating the sampling balloon to force a sampling surface of the sampling balloon into contact with the cervix, thereby transferring cervical cells from the cervix to the sampling surface of the sampling balloon. The sampling balloon is then deflated and withdrawn. Then, the adhered cervical cells are treated with a marker and are optically analyzed.
