Endoscopy is primarily used for visualizing and accessing internal organs, such as the gastrointestinal tract, respiratory system, or urinary tract, using a flexible tube with a camera. However, it is not typically used for examining lymph nodes directly.
Lymph nodes are usually assessed through other methods, such as imaging techniques (like ultrasound, CT scans, or MRI) or through biopsy procedures that may involve fine-needle aspiration (FNA) or surgical removal. In some cases, endoscopic ultrasound (EUS) can be used to visualize lymph nodes, particularly in areas like the mediastinum (the area between the lungs) or the abdomen.
If you have specific questions about lymph nodes or related procedures, it's best to consult with a healthcare professional who can provide guidance based on your individual health needs.
