When an entire lump or suspicious area is removed, the procedure is called an '''excisional biopsy'''. 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 biopsy]]. Biopsies are most commonly performed for insight into possible [[cancerous]] or inflammatory conditions.

An ''excisional biopsy'' is an attempt to remove an entire lesion. When the specimen is evaluated, in addition to diagnosis, the amount of uninvolved tissue around the lesion, the ''surgical margin'' of the specimen is examined to see if the disease has spread beyond the area biopsied. "Clear margins" or "negative margins" means that no disease was found at the edges of the biopsy specimen. "Positive margins" means that disease was found, and a wider excision may be needed, depending on the diagnosis.{{citation needed|date=February 2022}} [29] => [30] => When intact removal is not indicated for a variety of reasons, a wedge of tissue may be taken in an ''incisional biopsy''. In some cases, a sample can be collected by devices that "bite" a sample. A variety of sizes of needles can collect tissue in the lumen (''core biopsy'').

[31] => [32] => [[Pathology|Pathologic]] examination of a biopsy can determine whether a lesion is [[Benign tumor|benign]] or [[Malignant tumor|malignant]], and can help differentiate between different types of cancer. In contrast to a biopsy that merely samples a lesion, a larger excisional specimen called a resection may come to a pathologist, typically from a surgeon attempting to eradicate a known lesion from a patient. For example, a pathologist would examine a [[mastectomy]] specimen, even if a previous nonexcisional breast biopsy had already established the diagnosis of breast cancer. Examination of the full mastectomy specimen would confirm the exact nature of the cancer (subclassification of tumor and histologic "grading") and reveal the extent of its spread ([[Staging (pathology)|pathologic "staging"]]).

Biopsy

A biopsy is a medical procedure in which a small sample of tissue or cells is taken from a person's body for examination under a microscope. This technique is commonly used to diagnose diseases such as cancer, infections, autoimmune disorders, and other conditions.

More about us

About

This technique is commonly used to diagnose diseases such as cancer, infections, autoimmune disorders, and other conditions. There are different methods of performing a biopsy depending on the location and nature of the suspected abnormality, including needle biopsies, core biopsies, and surgical biopsies. The samples obtained through biopsies are then analyzed by pathologists to determine if there are any abnormalities or diseases present. Biopsies can provide valuable information for planning treatment options and monitoring the progression of various diseases. This Wikipedia page provides comprehensive information about the different types of biopsies, their uses, potential risks, and the procedures involved. It also includes information about the history of biopsies, advancements in the field, and the potential future developments in this area of medical diagnosis.
