An incisional biopsy or core biopsy samples a portion of the abnormal tissue without attempting to remove the entire lesion or tumor. When a sample of tissue or fluid is removed with a needle in such a way that cells are removed without preserving the histological architecture of the tissue cells, the procedure is called a needle aspiration ...
A punch biopsy is essentially an incisional biopsy, except it is round rather than elliptical as in most incisional biopsies done with a scalpel. Incisional biopsies can include the whole lesion (excisional), part of a lesion, or part of the affected skin plus part of the normal skin (to show the interface between normal and abnormal skin).
A deeper biopsy down to the dermis or subcutaneous tissue might reveal the true cancer. An excision biopsy is ideal, but not practical in most cases. An incisional or punch biopsy is preferred. A shave biopsy is least ideal, especially if only the superficial portion is acquired. [citation needed]

A biopsy is a small piece of tissue removed primarily for the purposes of surgical pathology analysis, most often in order to render a definitive diagnosis. Types of biopsies include core biopsies , which are obtained through the use of large-bore needles, sometimes under the guidance of radiological techniques such as ultrasound , CT scan , or ...
Establishing the precise subtype: Initially, an incisional or excisional biopsy is preferred. A core needle biopsy is discouraged except in case a lymph node is not easily accessible. Fine-needle aspiration is only acceptable in selected circumstances, in combination with immunohistochemistry and flow cytometry.
After extraction, all specimen containers must be labeled with at least two of the following identifiers (at the time of collection): patient's name, date of birth, hospital number, test request form number, accession number, or a unique random number. All specimens should be labeled with the patient present.
An open biopsy consists of surgically removing all or part of a node. [citation needed] The patient lies on the examination table and is given a sedative. The skin over the biopsy site is cleansed, and a local anesthetic is injected (occasionally, a general anesthetic is given). A small incision is made, and the lymph node or part of the node ...
