What does SNB mean in PHYSIOLOGY
Sentinel node biopsy, or SNB, is a closely monitored surgical procedure used to diagnose and stage certain types of cancer. It is most often used to detect the spread of cancer from its primary site, such as the breast, skin, lungs, and other organs. In an SNB procedure, a colored dye or tracer material is injected near the tumor site. Then, using special imaging techniques such as X-ray technology or fluorescent light detected with a microscope, healthcare professionals are able to locate and map out the lymph nodes closest to the tumor. The sentinel node(s) are then surgically removed for analysis under a microscope. If found to be cancer-free there is a greatly reduced risk of further metastasis (spread) in other lymph nodes; if it tests positive for cancer cells it helps indicate that additional measures may need to be taken.

What Does SNB Stand For?
SNB stands for Sentinel Node Biopsy.
What Is SNB Used For?
SNB is commonly used as part of staging procedures for breast cancers and melanomas and has recently been recruited in trials investigating its potential utility in other types of cancer such as lung and gastric tumors. In addition, where appropriate SNB has been reported to reduce morbidity associated with more extensive surgeries such as axillary lymph node dissection (ALND).
Essential Questions and Answers on Sentinel Node Biopsy in "MEDICAL»PHYSIOLOGY"
What is a Sentinel Node Biopsy?
A sentinel node biopsy is an invasive surgical procedure used to analyze the spread of cancer cells through the lymphatic system. By removing and testing the lymph nodes closest to the tumor, doctors can determine if cancer has spread further into other parts of the body.
When is a Sentinel Node Biopsy performed?
A Sentinel Node Biopsy is usually performed prior to any other type of cancer removal surgery (such as lumpectomies or mastectomies) in order to help determine whether treatment options should be adjusted.
Who performs a Sentinel Node Biopsy?
Typically, sentinel node biopsies are performed by a specialized surgeon, such as an oncologic surgeon, but they may also be performed by another specialist depending on the patient's specific needs.
How is a Sentinel Node Biopsy done?
The procedure begins with the injection of a small traceable substance near the tumor site that will travel to and identify which lymph nodes are nearest to it. Once identified, these nodes are surgically removed for laboratory testing.
How long does a Sentinel Node Biopsy typically take?
The procedure itself usually takes between one to two hours from start to finish, but depends on several factors such as size and location of the tumor and how many lymph nodes need to be removed for analysis.
Are there any risks associated with a Sentinel Node Biopsy?
While generally considered safe, complications may include infection at the incision site or damage caused during surgery due to other structures in proximity of the sentinel node(s). Additionally, there is always inherent risk associated with any type of surgery.
Does a Sentinel Node Biopsy require anesthesia?
Yes, general anesthesia is often needed for this procedure though some surgeons may use local anesthesia only if possible. The amount of anesthesia used will depend on factors such as patient size/age and tumor size/location.
Is there discomfort associated with recovery after having a Sentinel Node Biopsy?
Yes; recovery after having this procedure can involve pain at the incision site and swelling around it due to inflammation caused by the surgery itself. This should subside over time but pain medication may be prescribed by your doctor until such time as it resolves.
Final Words:
Sentinel node biopsy (SNB) offers an important way for medical professionals to quickly diagnose and treat certain types of cancers without having to resort immediately to more wide-ranging surgeries like axillary lymph node dissection (ALND). By injecting traceable substances around certain neoplasms and using imaging scans like gamma ray imaging or flourescence microscopy surgeons can identify individual “sentinel” nodes which inform them if any disease beyond its primary location exists allowing for quicker decisions on treatment options in certain cases when available significantly reducing both patient morbidity time and cost associated with otherwise more invasive optioning plans which would otherwise commonly require thorough examination after completion of ALND procedures .
