Clinicians often use the term “biopsy” as a nonspecific description of obtaining a tissue sample for histopathologic interpretation. Because of this, two major categories of biopsy have been designated: pretreatment biopsy (tissue obtained before treatment initiation) or posttreatment biopsy (tissue obtained at the time of definitive tumor resection). All biopsy procedures, whether pretreatment or posttreatment, should be carefully planned with several factors in mind. These factors include known patient comorbidities, anatomic location of the mass, differential diagnoses, biopsy technique, eventual definitive treatment, and any neoadjuvant/adjuvant therapies that may need to be incorporated.
