Cytology and biopsies are tests used to analyze cells and tissues of the body, respectively, with the aim of diagnosing diseases such as cancer, infections, or cellular abnormalities.

Cytology involves the collection of cells, usually through scrapings or aspiration, and is used to evaluate changes in cells.

A biopsy, on the other hand, involves removing a small portion of tissue for detailed microscopic examination.

Both exams are fundamental for the early detection and definition of treatment for various conditions, especially cancer.
