Anal Pap smear
Anal Pap Smear
An Anal Pap Smear (pronounced: /ˈeɪnəl pæp smɪər/) is a medical procedure used to detect potential precancerous and cancerous processes in the anus and anal canal. The procedure is named after the Greek doctor George Papanicolaou, who developed the technique.
Etymology
The term "Pap smear" is derived from the name of its inventor, Dr. George Papanicolaou, a Greek physician who first developed the procedure in the early 20th century. The term "anal" is derived from the Latin word "anus," which refers to the terminal part of the digestive tract.
Procedure
The Anal Pap Smear procedure involves the collection of cells from the squamous epithelium of the anus and anal canal. These cells are then examined under a microscope to detect any abnormal changes that may indicate a risk of cancer. The procedure is similar to a cervical Pap smear, but the sample is taken from the anus instead of the cervix.
