I am sorry to hear about your friend's diagnosis, but glad to hear that her lymph nodes are clear.
Most of us on this site are cancer pilgrims and don't have any medical knowledge. You might get a more educated reply by asking the nurses on this site, who have the knowledge to answer your question.
Your friend is lucky to have your support.
I hope that you get the answers you seek. Please keep in touch. We are always here for both of you whenever you feel like talking.
