A biopsy is the removal of a small tissue sample so it can be examined under a microscope.
A biopsy is usually done because a scan, lump, swelling, or other abnormal finding needs a clearer diagnosis rather than because the biopsy itself causes symptoms.
Imaging helps when the target is inside the body, difficult to feel, close to important structures, or needs the safest possible needle path.
Ultrasound, CT, mammography, or MRI may be used to guide the needle accurately into the right area.
The next step depends on the pathology result and may range from reassurance to surgery, medicines, or other specialist treatment.
This entry explains the procedure. Before you go, read the longer prep guide or find a centre that performs it.
