Anatomic pathology is a branch of medicine that focuses on the diagnosis of diseases through the examination of tissues and organs. Pathologists study samples obtained from surgeries, biopsies, or autopsies to identify abnormalities, such as tumors or infections. This field plays a crucial role in understanding the nature of diseases and guiding treatment decisions. The process typically involves preparing tissue samples, staining them for visibility, and examining them under a microscope. Anatomic pathology helps in determining the cause of illness, assessing disease progression, and evaluating the effectiveness of treatments, making it essential for patient care and research.
