A pathologist is a medical doctor who specializes in diagnosing diseases by examining tissues, cells, and bodily fluids. They play a crucial role in understanding illnesses by studying samples taken from patients, often through biopsies or surgeries. Their findings help other doctors determine the best treatment options for patients. Pathologists often work closely with other healthcare professionals, such as surgeons and oncologists, to provide accurate diagnoses. They use advanced techniques, including microscopy and molecular testing, to identify diseases like cancer. Their expertise is essential in guiding patient care and improving health outcomes.
