2. Fine-needle aspiration - Wikipedia

   en.wikipedia.org/wiki/Fine-needle_aspiration

   Fine-needle aspiration biopsies are very safe for minor surgical procedures. Often, a major surgical (excisional or open) biopsy can be avoided by performing a needle aspiration biopsy instead, eliminating the need for hospitalization. In 1981, the first fine-needle aspiration biopsy in the United States was done at Maimonides Medical Center. [1]

3. Lymph node biopsy - Wikipedia

   en.wikipedia.org/wiki/Lymph_node_biopsy

   Lymph node biopsy is a test in which a lymph node or a piece of a lymph node is removed for examination under a microscope (see: biopsy). The lymphatic system is made up of several lymph nodes connected by lymph vessels. The nodes produce white blood cells (lymphocytes) that fight infections. When an infection is present, the lymph nodes swell ...

   Establishing the precise subtype: Initially, an incisional or excisional biopsy is preferred. A core needle biopsy is discouraged except in case a lymph node is not easily accessible. Fine-needle aspiration is only acceptable in selected circumstances, in combination with immunohistochemistry and flow cytometry.

5. Cervical lymphadenopathy - Wikipedia

   en.wikipedia.org/wiki/Cervical_lymphadenopathy

   Lymph nodes may become enlarged in malignant disease. This cervical lymphadenopathy may be reactive or metastatic. [1] Alternatively, enlarged lymph nodes may represent a primary malignancy of the lymphatic system itself, such as lymphoma (both Hodgkin's and non-Hodgkin's), [6] lymphocytic leukemia, [1] Lymphadenopathy that lasts less than two weeks or more than one year with no progressive ...

6. Lymphadenopathy - Wikipedia

   en.wikipedia.org/wiki/Lymphadenopathy

   Fine-needle aspiration cytology (FNAC) has sensitivity and specificity percentages of 81% and 100%, respectively, in the histopathology of malignant cervical lymphadenopathy. [27] PET-CT has proven to be helpful in identifying occult primary carcinomas of the head and neck, especially when applied as a guiding tool prior to panendoscopy, and ...

7. Biopsy - Wikipedia

   en.wikipedia.org/wiki/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.
