Lümfisõlmebiopsia

Lümfisõlmebiopsia is a medical procedure involving the removal of a sample of tissue from a lymph node for examination. Lymph nodes are small, bean-shaped glands that are part of the immune system, filtering waste and foreign substances from the body. When a lymph node becomes enlarged or abnormal, a biopsy may be performed to determine the cause.

The procedure can be done in several ways. A fine-needle aspiration (FNA) involves using a thin needle to extract cells. A core needle biopsy uses a larger needle to remove a small cylinder of tissue. In some cases, a surgical biopsy may be necessary, where a surgeon removes either a portion or the entire lymph node. This is often done under local or general anesthesia.

A pathologist examines the tissue sample under a microscope to look for abnormalities such as infection, inflammation, or cancer. The results of a lümfisõlmebiopsia are crucial for diagnosing conditions like lymphoma, leukemia, or metastatic cancer, and for staging cancer if it has spread. It helps guide treatment decisions for various diseases. The recovery time and potential complications depend on the type of biopsy performed.
