What Is a Biopsy?

A biopsy is when a doctor removes a tissue sample from the body to test for a disease. They may also look for other changes that may show your risk for disease.

The method your doctor or surgeon uses depends on the disease they suspect and where it is in your body.

They may remove tissue by:

Needle.
Minimally invasive surgery.
Standard surgery.

What Happens to My Biopsy Sample in the Lab?

After your doctor or surgeon takes your tissue sample, they send it to the pathology lab in a secure container.

When your tissue sample arrives in the pathology lab, our experts assign it a unique number.

Then we:

Preserve your sample in special fluids.
Weigh and measure it.
Embed it in special paraffin wax.
Cut the sample into thin slices and look at it under the microscope.

We also use other testing techniques if needed.

After we study your sample, we:

Decide whether the tissue is normal or diseased.
Write a pathology report to explain our biopsy findings to your doctor.

The process most often takes 48 to 72 hours from biopsy to diagnosis. But in some cases, it may take longer.
