A biopsy is the removal of a small piece of tissue for lab examination - the definitive answer to questions scans and blood tests can only raise.
Types range from fine-needle aspiration and core needle biopsies under local anesthesia, through skin punch and shave biopsies, to endoscopic and surgical samples. Most are outpatient, minutes long, with a few days of mild soreness; the pathology report drives everything that follows.

What is a biopsy?
A biopsy is the removal of a small piece of tissue so a lab can examine it under a microscope - and it matters because many questions, above all "is this cancer," cannot be answered definitively any other way. Scans and blood tests raise or lower suspicion; the biopsy settles it. MedlinePlus describes several types: needle biopsies done under local anesthesia (fine-needle aspiration pulls cells through a thin needle; core biopsy takes a small cylinder of tissue), punch and shave biopsies for skin, endoscopic biopsies taken through a scope, and surgical biopsies for larger or deeper samples. Most are outpatient procedures measured in minutes, with local numbing and a few days of mild soreness. The pathologist's report classifies what was found - normal tissue, inflammation, precancer, or cancer - and that classification drives everything that follows.
