What is an incisional biopsy used for?

An incisional biopsy is a surgical procedure that involves removing a small sample of tissue from a tumor or suspicious lesion for diagnostic purposes. This technique is particularly useful when the tumor is too large or its complete removal would cause significant complications or morbidity. By taking a piece of the tumor tissue, healthcare providers can perform histological examinations to determine the presence of cancer cells, identify the type of cancer, and inform subsequent treatment decisions.

This method is vital in oncology, as it provides critical information without requiring the removal of the entire tumor, which might not always be feasible or safe. Understanding the characteristics of the tumor from the biopsy sample can guide treatment plans, such as whether surgery, chemotherapy, or radiation is necessary based on the tumor type and stage.
