No, a biopsy doesn't always mean complete removal. A biopsy is the removal of a sample of cells or tissues for examination by a pathologist. The pathologist then analyzes this sample under a microscope or through other tests to determine the presence of disease or other abnormalities. The amount of tissue removed varies greatly depending on the type of biopsy and the location.
Understanding the Biopsy Procedure
A biopsy involves taking a small piece or sample of tissue, not necessarily the entire affected area. Think of it like taking a tiny piece of a pie to determine its flavor; you don't need the whole pie to understand the taste.
Here are some examples to illustrate:
- Needle biopsy: A thin needle is inserted to extract a small tissue sample. This is a minimally invasive procedure.
- Incisional biopsy: A small incision is made to remove a portion of the abnormal tissue.
- Excisional biopsy: The entire abnormal area is surgically removed. This is technically a removal, but it's still considered a type of biopsy because the primary purpose is diagnostic examination.
The reference states: "The removal of cells or tissues for examination by a pathologist. The pathologist may study the tissue under a microscope or perform other tests on the cells or tissue. There are many different types of biopsy procedures." This highlights that while removal is involved, the key objective is examination, not necessarily complete removal of the affected area.
