![]() It’s usually a vertical cut from upper to lower abdomen. Laparotomy and thoracotomyĪ laparotomy is a type of surgery that cuts into the abdomen (belly). Procedures like this that look inside the chest are called thoracoscopy and mediastinoscopy. A small cut is made in the abdomen, and the laparoscope is passed through it to see inside. Laparoscopy is much like endoscopy but uses a slightly different scope (a laparoscope) to look inside the abdomen (belly) and remove tissue samples. Laparoscopic, thoracoscopic, and mediastinoscopic biopsy For instance, a bronchoscope is used to look inside the lungs and bronchi (breathing tubes), and a colonoscope is used to look inside the colon and rectum (large intestine). Some endoscopes are named for the part they are used to look at. Another type of endoscope is used to look at the upper part of the digestive tract: the esophagus (the tube that connects the throat to the stomach), stomach, and first part of the intestine. For example, one type of endoscope is used to look at the inside of the nose, sinuses, and throat. Tissue samples can also be taken out through the endoscope.ĭifferent types of endoscopes are used to look at different parts of the body. It allows a doctor to look inside different parts of the body. Endoscopic biopsyĪn endoscope is a thin, flexible, lighted tube that has a lens or a video camera on the end. If the tumor is inside the chest or abdomen (belly), general anesthesia is used (drugs are used to put the patient into a deep sleep so they will feel no pain). This is often done using local or regional anesthesia (drugs are used to numb the area). In this type of biopsy, a surgeon cuts through the skin to remove the entire tumor (called an excisional biopsy) or a small part of a large tumor (called an incisional biopsy). Processing core biopsy samples usually takes longer than FNA biopsies, so getting the results of those tests also might take longer. (For more on this, see our breast biopsy information.) Like FNA, a core biopsy can sample tumors that the doctor can feel as well as smaller ones that must be seen using imaging tests.ĭoctors sometimes use special vacuum tools to get larger core biopsies from breast tissue. The core needle biopsy is done with local anesthesia (drugs are used to make the area numb) in the doctor’s office or clinic. They remove a small cylinder of tissue (about 1/16 inch in diameter and 1/2 inch long). Needles used in a core biopsy are slightly larger than those used in FNA. Although FNA is a type of biopsy, it’s also classified as a cytology test. The disadvantage is that sometimes this needle can’t remove enough tissue for a definite diagnosis. The main advantages of FNA are that the skin doesn’t have to be cut, and in some cases it’s possible to make a diagnosis the same day. If the tumor is deeper inside the body and can’t be felt, the needle can be guided while being watched on an imaging test such as an ultrasound or CT scan. ![]() The doctor can aim the needle while feeling the tumor, if it’s near the surface of the body. Core needle biopsy (also called core biopsy)įine needle aspiration (FNA) uses a very thin, hollow needle attached to a syringe to take out a small amount of fluid and very small pieces of tissue from the tumor.Fine needle biopsy (also called fine needle aspiration).For more details, go to the diagnosis information on specific type of cancer you want to learn about. The most common biopsy types used in cancer diagnosis are discussed here. These biopsies are often done by surgeons, but can also be done by other doctors. Other types of biopsies remove tumor samples through a thin needle or through an endoscope (a flexible lighted tube that’s put into the body). Some types of biopsies remove an entire organ. For instance, the methods used for skin biopsies are very different from those used for brain biopsies. How samples are taken depends on where the tumor is and what type of cancer is suspected. Tissue or cell samples can be taken from almost any part of the body. ![]()
