A biopsy is a sample of tissue taken from the body in order to examine it more closely. A doctor should recommend a biopsy when an initial test suggests an area of tissue in the body isn't normal.
Doctors may call an area of abnormal tissue a lesion, a tumor, or a mass. These are general words used to emphasize the unknown nature of the tissue. The suspicious area may be noticed during a physical examination or internally on an imaging test.
Incidence and Mortality
Estimated new cases and deaths from laryngeal cancer in the United States in 2014:
New cases: 12,630.
The larynx is divided into the following three anatomical regions:
The supraglottic larynx includes the epiglottis, false vocal cords, ventricles, aryepiglottic folds, and arytenoids.
The glottis includes the true vocal cords and the anterior and posterior commissures.
The subglottic region begins about 1 cm below...
In some cases, a biopsy of normal-appearing tissue may be done. This can help check for cancer spread or rejection of a transplanted organ.
In most cases, a biopsy is done to diagnose a problem or to help determine the best therapy option.
Types of Biopsies
There are many different kinds of biopsies. Nearly all of them involve using a sharp tool to remove a small amount of tissue. If the biopsy will be on the skin or other sensitive area, numbing medicine is applied first.
Here are some types of biopsies:
Needle biopsy. Most biopsies are needle biopsies, meaning a needle is used to access the suspicious tissue.
CT-guided biopsy. A person rests in a CT-scanner; the scanner's images help doctors determine the exact position of the needle in the targeted tissue.
Ultrasound-guided biopsy. An ultrasound scanner helps a doctor direct the needle into the lesion.
Bone biopsy. A bone biopsy is used to look for cancer of the bones. This may be performed via the CT scan technique or by an orthopedic surgeon.
