What is the study of cells called?

Cytology is the study of cells, focusing on their structure, function, and significance. This field involves examining individual cells to understand their characteristics and how they contribute to the health or disease state of an organism. Cytology plays a crucial role in diagnosing various medical conditions, particularly cancer, by analyzing cell samples obtained from different tissues or bodily fluids.

The other fields mentioned serve different purposes: histology pertains to the study of tissues and their organization; pathology is concerned with the study of disease processes and includes both the examination of tissues and cells; mycology focuses specifically on fungi. Each of these areas is essential in the broader field of biology and medicine, but for the specific study of cells, cytology is the correct term.
