How long does a pathology report take?

According to the National Cancer Institute, the pathologist typically sends a pathology report to the doctor within 10 days after the biopsy or surgery is performed.

The timing depends on how the tissue is prepared. The most common approach uses fixed (permanent) sections, in which the tissue is chemically stabilized, embedded in paraffin wax, sliced into very thin sections, placed on slides, and stained. Preparing these fixed sections normally takes several days, and they provide the maximum detail.

Frozen sectioning is a faster approach used when an immediate answer is needed—for example, during surgery to give the surgeon a rapid diagnosis while the patient is still in the operating room. A frozen section can be prepared and examined in about 15 to 20 minutes. However, fixed sections preserve more detail and are more commonly used to make a diagnosis.

One thing to keep in mind: report results often appear in the patient portal at the same time the doctor receives them, so a person may see the report before the doctor has reviewed it. The doctor in charge of treatment will explain the findings and what they mean.
