Tumor Biopsy
Once a mass has been discovered, it will often require a tissue sample/biopsy in order for the pathologist to determine the diagnosis. This can be a challenging time for patients as undergoing biopsies can be difficult to bear for patients and loved ones.

Therefore, the City of Hope interventional oncology team offers minimally invasive, percutaneous or transvenous biopsies that can be conducted as outpatient procedures in the evaluation of liver, kidney, thyroid, bone, lung, and other soft tissue masses.

Depending on the type and location of the mass being tested, the doctor will either perform Fine Needle Aspiration (FNA) or a Core Needle Biopsy (CNB), which will immediately be sent to the cytopathologist or surgical pathologist for special staining and results.
