Cytopathology (from Greek κύτος, kytos, "a hollow"; πάθος, pathos, "fate, harm"; and -λογία, -logia) is a branch of pathology that studies and diagnoses diseases on the cellular level.
The discipline was founded by George Nicolas Papanicolaou in 1928..
Cytology is the examination of individual cells and small clusters of cells, and may be used for the diagnosis and screening of diseases, including cancers.
Cytology can also be referred to as cytopathology.
Samples for cytology can be obtained in more than one way.
Fine needle aspiration (FNA) is a type of biopsy in which tumor samples are taken through thin needles.
Scrape or brush cytology is another technique in which cells are scraped or brushed from the organ or tissue being tested.
Samples from the esophagus, stomach, bronchi (breathing tubes th.
A cytopathologist examines and identifies the normal and abnormal cells on the slide using a microscope.
Procedures to gather cells for cytology are often less invasive than other forms of biopsy, and therefore maycause less discomfort, be less likely to result in serious complications, and cost less to perform.
In some situations, however, where a piece of tissue is removed rather than individual cells, a different type of biopsy may be required to c.
Because this analysis is performed on cells that had been already gathered during initial diagnostic procedures, there is no additional preparation, aftercare, or risks for the patient.
The only procedure, aftercare, or risks to note would be those associated with the sample collection itself.
Diagnostic tests are used to detect a disease in individuals who have signs, symptoms, or some other abnormality that is indicative of disease.
A screening testidentifies those who might have a certain disease, sometimes before they develop any symptoms, but does not absolutely prove that disease is present.
If a screening test is positive, a diagn.
Cytology is the study of individual cells in a patient to exam for abnormalities or pathogenic illnesses.
This is different from histology as that is the study of whole tissues, not individual cells.
Can cytology detect cancer.
Yes, cytology is done to test for individual cells to see if those cells are cancerous.
