Whats The Difference Between A Needle Directed Biopsy And A Sentinel Node Biopsy
Size: A needle-directed biopsy means a hollow needle is stuck into a tumor or lymph node, and only the amount of tissue that fits inside the needle is removed. A sentinel node biopsy removes several lymph nodes entirely and the entire lymph node is examined under the microscope. A sentinel node biopsy requires an injection ahead of time to see which nodes are first in the chain of lymph nodes. ...Read moreSee 2 more doctor answers
Biopsy is tissue removed by needle or cutting to remove part of a body part. It is usually a small amount of material that is processed by a pathologist. Most of the time it is stained and looked at through a microscope to arrive at a diagnosis. Special processes are done for some tissues or problems. The purpose is to tell what the problem is (diagnosis). ...Read more
Little difference.: Think of a lymph node as a small filter. All lymph nodes act as filters. However, certain lymph nodes are the very first filters in line- they are called sentinel lymph nodes. The idea is that if the sentinel node is removed and negative, the chances of other lymph nodes further down the line being positive is small. You take out less nodes and have less complications! ...Read more
Biopsy of lymph node: Lymph nodes are biopsied to see if cancer has spread beyond the primary site. Using a radioactive tracer and dye, the lymph nodes closest to a tumor can be identified and biopsied without having to remove all the potential draining nodes which can lead to complications. Most often done with breast cancer and melanoma. ...Read more
Sample lymph nodes: This is a surgical procedure used to evaluate the lymph nodes under the arm. A radioactive tracer and/or blue dye is injected into the breast prior to surgery. These substances travel to the lymph nodes so the surgeon can see them. He/she takes out one to four (on average) lymph nodes to see if cancer has spread. The benefit is a decrease in risk of lymphedema of the arm. ...Read moreSee 1 more doctor answer
Usually before.: Sentinel lymph node biopsy is usually done at the time of lumpectomy for breast cancer. The information gained is used in the decision making as to whether adjuvant chemotherapy should be given to increase the likelihood of cure. Rarely, it might be done after chemotherapy if the initial role of chemo was to shrink the tumor to allow surgery (neoadjuvant chemotherapy). ...Read more

Simple: A fine needle aspiration biopsy means using a thin needle (like the ones used to draw blood) to draw a very small tissue or cell sample from the lymph node. The sample is examined under microscope by a pathologist who can often make a diagnosis without the need for a surgical procedure to remove an entire node ...Read more

It is first node to which lymphatic drainage and metastasis from a cancer goes to. A biopsy is a procedure that removes a small piece of living tissue from your body. The tissue is examined with a microscope for signs of damage or disease. Biopsies can be done on all parts of the body. A biopsy is the only test that can tell for sure if a ...Read more
