What Is a Biopsy Done With?

The method depends on where the area is and how much tissue the laboratory needs. A needle may collect cells or a narrow core through the skin. A surgical tool can remove part or all of a visible area. An endoscope allows sampling from inside the body through a natural opening. Imaging such as ultrasound or computed tomography may guide the instrument to the intended site.

After collection, a pathologist examines the sample under a microscope. Additional laboratory methods can identify proteins or other features in the cells; immunohistochemistry is one such method.

Ask which biopsy method is planned, whether you should pause any medicines that affect bleeding, and whether you need to avoid food or drink. Tell the team about allergies, pregnancy, implanted devices, and medicines or supplements. Arrange practical support if sedation is planned, and follow the wound-care instructions after the sample is taken.

Contact the clinical team promptly for bleeding that does not settle with firm pressure, worsening redness or swelling, pus, fever, or pain that is increasing rather than easing. Seek urgent help for severe breathing difficulty, fainting, or rapidly worsening symptoms after the procedure.

Which instrument will collect my sample, and will imaging guide it? How will the area be numbed? When should I expect the pathology result, and could further testing be needed?
