2. How many lymph nodes<br />
are involved?<br />
The more lymph nodes have cancer<br />
cells in them, the more serious the cancer<br />
might be. For this reason, doctors use<br />
the number of involved lymph nodes<br />
to help make treatment decisions.<br />
Doctors also look at the amount of<br />
cancer in the lymph nodes.<br />
You may see these words<br />
describing how much cancer<br />
is in each lymph node:<br />
microscopic:<br />
Only a few cancer cells are in the node.<br />
A microscope is needed to find them.<br />
gross:<br />
There is a lot of cancer in the node. You can<br />
see or feel the cancer without a microscope.<br />
extracapsular extension:<br />
<strong>Cancer</strong> has spread outside the wall of<br />
the node.<br />
