Biopsy is a medical procedure in which a small sample of tissue or cells is extracted from the body for analysis.
Its purpose is to obtain precise information about a potential disease, identify the presence of abnormal cells, or determine the type and grade of a tumor.
The sample is examined in the laboratory by a pathologist, who conducts various tests to obtain an accurate diagnosis.
Biopsy can be performed using different methods, such as tissue extraction with a needle, a small surgical incision, or the use of endoscopic instruments.
