What is Cytology?
Cytology is the study of cells. The test is usually used to look for cancers and precancerous changes. It may also be used to look for infections in cells. The test differs from a biopsy in that only cells are examined, not pieces of tissue.
A common application of cytopathology is the Pap smear used as a screening tool, to detect precancerous lesions of the Uterine cervix and and prevent Cancer of the cervix.
Cytopathologic techniques are used in the examination of virtually all body organs and tissues:
- Gynaecologic cytology - Pap smear
