Cytology and biopsy are two distinct but often complementary diagnostic procedures used in medicine to examine cells and tissues. Cytology involves the microscopic examination of individual cells that have been shed or collected from the body. This can include cells from fluids like urine, blood, or cerebrospinal fluid, or cells scraped from surfaces like the cervix (Pap smear) or obtained through fine-needle aspiration. The goal of cytological examination is to detect abnormalities such as infection, inflammation, or the presence of cancerous or precancerous cells. Cytology is generally a less invasive procedure.

Biopsy, on the other hand, involves the removal of a small piece of tissue from the body for examination. This tissue sample is typically processed and thinly sliced to allow for detailed microscopic analysis by a pathologist. Biopsies can be obtained through various methods, ranging from minimally invasive procedures like needle biopsies to surgical excisions. They are often performed when a suspicious lesion or mass is identified and a definitive diagnosis is required. Biopsies provide information about the cellular structure, tissue architecture, and the relationship between cells, which can be crucial for diagnosing diseases, staging cancers, and guiding treatment decisions. While cytology can suggest the presence of disease, a biopsy often provides a more definitive diagnosis.
