A positive sentinel node suggests that cancer cells have spread from the primary tumor to nearby lymph nodes. Further evaluation and treatment, such as lymph node dissection and adjuvant therapy, may be needed to determine the extent of spread and reduce the risk of recurrence.

What is the outer part of a node?
The outer part of a node is often referred to as the parent node or the root node. It is the main starting point of a tree data structure, from which all other nodes branch out. The parent node does not have a direct parent, hence why it is considered the outer part of the node hierarchy.
What is the most important structure of the human heart?
It is supposed to be the sinus node and the conducting tissue. It includes the AV node and bundle of HIS. The sinus node generate the impulse in the heart for contraction. The AV node and bundle of HIS transmits the impulse to the ventricles.
Is sensitive tissue in the right atrium wall that begins the heartbeat called atrioventricular node?
No, the sensitive tissue in the right atrium wall that begins the heartbeat is called the sinoatrial (SA) node, not the atrioventricular (AV) node. The SA node is often referred to as the heart's natural pacemaker as it initiates the electrical impulses responsible for coordinating the heartbeat. The AV node is located in the septum between the atria and ventricles and serves to delay the impulse to allow the atria to fully contract before the ventricles do.
What node is located in the inferior portion of the interatrail septum?
The Atrioventricular (AV) node is located in the inferior portion of the interatrial septum. It is a specialized cluster of cells that conducts electrical signals from the atria to the ventricles, helping to regulate the heartbeat.
Do nerve impulses travel down the internodal pathways from the av node?
No, nerve impulses travel down the internodal pathways towards the AV node, not from it. The internodal pathways conduct the impulse from the SA node to the AV node, assisting in the synchronization of the heart's electrical activity.
What is lymphiscintigraphy?
Lymphoscintigraphy (sentinel lymph node mapping) is an imaging technique used to identify the lymph drainage basin, determine the number of sentinel nodes, differentiate sentinel nodes from subsequent nodes, locate the sentinel node in an unexpected location, and mark the sentinel node over the skin for biopsy.
What is sentinel node?
It is the first node in which the lymphatic drainage occura in a particular area.
A sentinel node is?
It is the first node in which the lymphatic drainage occura in a particular area.
What is a sentinel node?
It is the first node in which the lymphatic drainage occura in a particular area.
What distinguishes a sentinel node from other nodes?
A sentinel lymph node is the first lymph node that drains a cancer. If a cancer has not spread to the first draining lymph node near a cancer, there is a high likelihood it has not spread elsewhere.
What is the significance of sentinel lymph node?
A sentinel lymph node is the first lymph node that drains a cancer. If a cancer has not spread to the first draining lymph node near a cancer, there is a high likelihood it has not spread elsewhere.
What node biopsy is performed a the beginning of the treatment of breast cancer?
sentinel
Can you delete the head node from doubly linked list?
If by 'head node' you simply mean the first node, then yes; but if 'head node' means the special element which is not supposed to ever be deleted (aka sentinel node), then no.
What is sentinel lymph node mapping and biopsy?
A new technique called sentinel lymph node mapping and biopsy often eliminates the need for removing some or all lymph nodes by testing the first lymph node for cancer.
How do you usually indicate the end of a linked list?
The last node typically points to NULL (meaning there is no next node). Some implementations make use of a sentinel node as this can make it easier to implement some algorithms (because the sentinel always exists even when the list is empty). In such implementations, both the head and the tail node may be sentinels.
What is learned by the procedure known as sentinel node mapping?
These sentinel nodes are thus identifiable and are the most likely to harbor any regional metastatic disease. If these nodes alone are biopsied and are normal, the rest of the lymph node group can be spared.
What kind of biopsy is performed at the beginning of breast cancer treatment?
Sentinel-node biopsy
