Alternatives to the traditional pap smear are on the way. Here's what to know.

Alternatives to the often dreaded pap smear may be on the horizon for cervical cancer screenings. 

Typically, the procedure involves inserting a device called a speculum, which helps open the vaginal canal, in order for a swab to be inserted and brushed against the cervix to collect a cell sample. All this is done while laying back with feet hoisted in stirrups to keep legs spread apart. 

For some, pap smears are an uncomfortable but necessary evil when it comes to health screenings. For others, it's an experience bad enough to avoid a doctor's visit, risking not detecting cancer cells early.
