In this video Dr O'Donovan explains key things you need to know about a biopsy.

A biopsy is a medical procedure where a sample of tissue is taken from the body for examination under a microscope to help diagnose or rule out various conditions, including cancer. It involves removing a small portion of tissue (like a skin sample, bone marrow, or organ tissue) and sending it to a laboratory for analysis.

Purpose of a Biopsy:
Diagnosis: Biopsies help determine if a suspicious area or lump is cancerous, benign, or indicates other conditions.
Further Information: They can provide information about the type of cancer, how quickly it's growing, and other details needed for treatment planning.
Ruling out Conditions: Biopsies can also be used to rule out certain diseases or conditions.

Types of Biopsies.

There are different types of biopsies:

Needle Biopsy:
A needle is used to extract a sample of tissue, such as a fine-needle aspiration or core needle biopsy.
Surgical Biopsy:
A small incision is made to remove a sample of tissue, like in an incisional or excisional biopsy.
Endoscopic Biopsy:
An endoscope (a flexible tube with a camera and tools) is used to reach and sample tissue in areas like the digestive tract or lungs.

How is a Biopsy Performed?
Location:
Biopsies can be performed on almost any part of the body, from skin to organs.
Anesthesia:
Local or general anesthesia may be used depending on the location and type of biopsy.

Procedure:
The method of obtaining the tissue sample varies depending on the type of biopsy and the location.
Analysis:
The tissue sample is sent to a laboratory where a pathologist examines it under a microscope to identify any abnormalities or changes.
