How will the biopsy affect my treatment plan?

Biopsy outcome. Biopsy means to take a tiny part of the affected organ and examine it under the microscope and in other ways for diagnostic purposes. Biopsy findings may diagnose cancer or rule it out. Biopsy is also done in other situations, e.g. Liver biopsy to diagnose a liver condition or its severity. Thus biopsy plays an important part in the diagnosis and prognosis of a patient's condition.
Diagnosis. A biopsy will yield a diagnosis and that will allow your treatment plan to be tailored to what best treats that condition. Best wishes.
