- Will I meet Dr. Fiser directly as a patient?
- While Pathologists like Dr. Fiser play a critical role in patient care, they primarily work behind the scenes in the laboratory, analyzing patient samples and consulting with other physicians. It's generally uncommon for patients to meet their pathologist directly, unless the pathologist has a subspecialty that involves some direct patient procedures (e.g., some hematopathologists performing bone marrow biopsies, though this is often done by hematologists/oncologists). Your primary interaction will be with your treating physician who orders the tests and discusses Dr. Fiser's findings with you.

- The turnaround time for pathology results can vary depending on several factors, including the type and complexity of the specimen, the number of specialized tests required (e.g., immunohistochemistry, molecular studies), and the overall lab workload. Simple biopsies might have results in a few days, while more complex cases or those needing extensive ancillary testing might take a week or longer. Your treating physician, who ordered the tests and receives the report from Dr. Fiser, is the best person to provide an estimated timeframe for your specific results.
