Getting biopsy results can take anywhere from two to 10 days. The length of time needed depends on how complicated the results are and how much time the pathologist needs to study the tissue and reach a diagnosis, according to Cancer.net.
Biopsy results typically take the form of a pathology report that contains a description of the tissue sampled, a description of how the cells looked under a microscope, and a diagnosis from the pathologist, as Mayo Clinic explains. Patients often need to go over their pathology reports with their physicians to understand the technical details. Pathology reports also often include recommendations for any further treatment.
