Aspiration biopsy

Aspiration Biopsy is a medical procedure used to extract cells or tissue samples from a patient's body for diagnostic purposes. This procedure is often used to diagnose various diseases, including cancer, infections, and inflammatory diseases.

Procedure

The procedure of an aspiration biopsy involves the use of a thin, hollow needle to extract a sample of cells or tissues. The needle is typically inserted into the area of the body where the abnormal cells or tissues are located. This could be a lump or mass in the breast, lung, liver, or other parts of the body. The needle is then used to aspirate, or draw out, a sample of the cells or tissues. This sample is then sent to a laboratory for further examination under a microscope by a pathologist.

Types of Aspiration Biopsy

There are several types of aspiration biopsy, including fine needle aspiration biopsy (FNAB), core needle biopsy (CNB), and bone marrow aspiration. The type of biopsy used often depends on the location and nature of the suspected disease.

Fine Needle Aspiration Biopsy

Fine needle aspiration biopsy is often used to investigate lumps or masses found in areas such as the breast or thyroid. The procedure involves using a thin needle to extract a sample of cells from the lump or mass.

Core Needle Biopsy

Core needle biopsy is similar to FNAB, but it uses a larger needle to extract a larger sample of tissue. This type of biopsy is often used when the doctor needs a larger sample for diagnosis.

Bone Marrow Aspiration

Bone marrow aspiration is used to diagnose diseases of the bone marrow, such as leukemia or lymphoma. The procedure involves inserting a needle into the bone marrow, usually in the hip bone, and extracting a sample of the marrow.

Risks and Complications

As with any medical procedure, aspiration biopsy carries some risks and potential complications. These may include pain, bleeding, infection, and in rare cases, damage to surrounding tissues or organs. However, these risks are generally low, and the procedure is considered safe when performed by a skilled healthcare professional.
