The method of obtaining a small biopsy depends on the location and nature of the tissue being sampled. Common techniques include:
Needle Biopsy: A thin needle is used to extract tissue or fluid, often guided by imaging techniques such as ultrasound or CT scans. Endoscopic Biopsy: A flexible tube with a camera (endoscope) is inserted into the body to obtain tissue samples from internal organs. Punch Biopsy: A circular blade is used to remove a small core of skin tissue, commonly used in dermatology. Excisional Biopsy: A small surgical procedure where an entire lump or suspicious area is removed for examination.
