A cytologist is a specialist in cytology, an area of biology that deals with the study of the  
structure, function, multiplication, life history, problems, diseases, and chemistry of the 
cell. A cell is the smallest, most basic unit of life, that is capable of existing by itself. 
Cytologists work closely with pathologists (who supervise them) to analyze cells for 
abnormalities, often to assess for cancer or pre-cancerous stages.  
 
Pathologists are doctors who interpret and diagnose the changes caused by disease in 
tissues and body fluids. Cancer is any of a large group of malignant diseases 
characterized by an abnormal, uncontrolled growth of new cells in one of the body 
organs or tissues. 
 
Cytologists generally work in laboratories and do not have much contact, if any, with 
actual patients. Many cytologists work is hospital laboratories, research laboratories, or 
private laboratories. In the U.S., certificates in cytotechnology are awarded via a 
Bachelor’s degree and/or a Master’s degree.  Some states require cytologists to also be 
licensed. Cytologists need to have good visual skills due to the types of visual analyses 
they need to do when studying samples under the microscope. Cytologist comes from 
the Greek word "kytos" meaning "a hollow (empty) cell," and the Greek word "logos" 
meaning "study." Put the two words together and you have "study (of) hollow cell(s)."
