Hello, this is Dr K.. Answers are not medical advice and do not constitute a doctor/patient relationship. I look forward to helping you today.
It depends on where the node is and the clinical scenario
I see you are posting multiple related questions and looking for answers on really only one topic, it makes experts reluctant to reply.
I would suggest you ask customer service to close out your remaining questions and start fresh. Ask for Dr David by request. He is an excellent specialist in oncology and can help you the most.
