Description
Why It’s Done:
This test is performed to:
• Diagnose cancer and determine whether a tumor is benign or malignant.
• Identify the type of cancer (e.g., carcinoma, sarcoma, lymphoma).
• Assess the tumor grade (how aggressive the cancer is).
• Evaluate the stage by determining depth of invasion, margin status, lymph node involvement, etc.
• Guide treatment planning, including surgery, chemotherapy, radiation, or targeted therapy.
• Monitor recurrence or progression in previously diagnosed patients.
It is especially important when dealing with large, irregular, or infiltrative tumors that require a more extensive pathological assessment.
Preparation:
• No preparation is needed for the test itself, but preparation may be required for the biopsy procedure, which is done beforehand.
• Depending on the location of the tumor, the biopsy may be done under:
o Local anesthesia (e.g., skin, breast)
o Sedation or general anesthesia (e.g., internal organs, complex resections)
• Inform your doctor of any:
o Medications, especially blood thinners
o Allergies to anesthesia
o Medical conditions that may affect surgery or healing
