Etymology
Origin of biopsy
Explanation
A biopsy is a sample of tissue or liquid from the body that helps determine if you have a disease. If your doctor finds a lump in part of your body, she will probably do a biopsy to see if it is cancerous or not. Bios means "life" and opsis means "see" or "sight," so a biopsy is a way for a doctor to look into your body, so to speak, by taking a sample of it. There are different kinds of biopsies, depending on where the tissue is that your doctor needs to look at. You might have a surgical biopsy or a less invasive biopsy by needle.
