What is Biopsy?

A biopsy is a medical procedure used to obtain a small sample of tissue from the body for examination under a microscope. The purpose of a biopsy is to determine the presence of disease or to diagnose a specific condition. Biopsies are often performed to confirm or rule out the presence of cancer, but they can also be used to diagnose other conditions, such as infections, inflammation, or benign (non-cancerous) growths.

There are several types of biopsies, each of which is designed to obtain tissue samples from different parts of the body. Some of the most common types of biopsies include:

• Fine-needle aspiration biopsy (FNAB): This type of biopsy uses a thin, hollow needle to obtain a small sample of tissue from a mass, such as a lump or nodule. FNABs are often performed on the thyroid gland or on lumps found in the breast.
• Core needle biopsy: This type of biopsy uses a larger, hollow needle to obtain a cylindrical tissue sample from a mass. Core needle biopsies are often performed on the breast, lymph nodes, or other organs.
• Surgical biopsy: This type of biopsy involves the removal of an entire lump or a portion of an organ for examination. Surgical biopsies are often performed on the liver, pancreas, or other organs.
• Endoscopic biopsy: This type of biopsy is performed using an endoscope, a long, flexible tube with a light and a camera on the end. Endoscopic biopsies are used to obtain tissue samples from the digestive tract, such as the stomach, colon, or small intestine.

The specific type of biopsy that is performed depends on the location and type of tissue being examined, as well as the suspected underlying condition. In general, biopsies are performed under local or general anesthesia and typically take only a few minutes to complete.

After a biopsy, the tissue sample is sent to a laboratory for examination by a pathologist, who will determine the presence of any abnormal cells or tissue. The results of a biopsy can be used to make a diagnosis, to determine the stage and extent of a disease, or to guide treatment decisions.

In conclusion, a biopsy is a medical procedure used to obtain a small sample of tissue from the body for examination under a microscope. The purpose of a biopsy is to determine the presence of disease or to diagnose a specific condition, such as cancer, infections, or benign growths. Biopsies are performed using different techniques, depending on the location and type of tissue being examined, and the results can be used to make a diagnosis and guide treatment decisions. If you are considering a biopsy, it is important to discuss the risks and benefits with your doctor to determine the best course of action.
