A lymph node can be described as an oval-shaped organ of the in the immune sysytem, They act as filters or traps for foreign particles and are important in the proper functioning of the immune system. The same way any filter works, they trap the bad stuff so the good can flow through.
One study found that only 2.6% of patients who had SLNB developed lymphedema, compared to 27% of patients who had ALND.
For stage I (early/lymph node negative), which comprises 40-45% of total cases, the five-year survival is 85-95%.
Approximately 10% to 20% of patients develop lymphedema after axillary lymph node removal. however if you get radiation your rate goes up to 50% and good chance of developing lymphedema
Sinoatrial Node (SA node)
The intrinsic rate of the AV node, also known as the inherent pacemaker rate, is the rate at which the AV node generates electrical impulses when not influenced by outside factors. It is typically around 40-60 beats per minute and serves as a backup pacemaker if the SA node fails to function properly. The AV node's intrinsic rate helps to regulate the heart rate and maintain cardiac function.

the SA node
The rate and pace of the heart are set by the SA node. There are backup systems in place if the SA node fails to do its job.
The rate of P waves will be faster than the rate of QRS complexes.
Portside had the most survival rate
60-100
The atrioventricular node is a part of electrical control system of the heart that co-ordinates heart rate.
