Than Dr. but I want to pay your attention I had thyroid cancer since the last july 2009. So, does the nodes indicate any mets. Are these nodes are not cancerous or non-cancerous.
Also, what is the suitable medication for these selling nodes?
These are non cancerous lymph nodes. They do not denote metastasis. An antibiotic course may be tried but these usually do not warrant any treatment.
