An abdominal or pelvic biopsy is where a small sample is taken from in your tummy (your abdomen) or your pelvis which is around your hip area.

Why do I need a biopsy?

You need a biopsy because something that was not normal was found in your tummy or pelvic area during another scan. Taking a sample will help us know how to treat you.
