What is the effect of an excisional biopsy?

An excisional biopsy involves the surgical removal of a portion of tissue for diagnostic purposes. This technique is commonly used to assess abnormal tissues, such as tumors, by taking out a sample that may include both the abnormal area and some surrounding healthy tissue. This allows for thorough examination under a microscope, making it possible to determine whether the tissue is benign or malignant.

This method is different from other procedures, such as incisional biopsies, where only a part of the lesion is removed, or fine needle aspirations, which involve drawing out cells but not tissue. The primary aim of an excisional biopsy is to provide sufficient tissue for a definitive diagnosis, which is critical in developing an effective treatment plan if cancer or another serious condition is identified.
