A histopathologist is a medical doctor who specializes in examining tissues and cells under a microscope to diagnose diseases. They play a crucial role in identifying conditions like cancer by analyzing samples taken from patients during surgeries or biopsies. Their expertise helps guide treatment decisions and ensures patients receive the appropriate care. In their work, histopathologists often collaborate with other healthcare professionals, such as surgeons and oncologists, to provide accurate diagnoses. They use advanced techniques and tools to study the microscopic structure of tissues, helping to uncover important information about a patient's health and the nature of their illness.
