Histopathology is the study of tissues under a microscope to diagnose diseases. It involves examining samples taken from patients, often through biopsies, to identify any abnormalities. This field is crucial for understanding conditions like cancer, where pathologists look for changes in cell structure and organization that indicate disease. Pathologists use special staining techniques to highlight different components of the tissue, making it easier to spot issues. By analyzing these samples, they can provide important information to doctors, helping them make informed decisions about treatment. Overall, histopathology plays a vital role in modern medicine and patient care.
