I wonder if this is a question for one of the nurses (who you can ring at the number above - they are excellent). Speaking as someone with 19/21 lymph nodes infected, including the sentinel node, I am a little envious but, to my knowledge 14 months on, nothing has spread so all I can say a rousing three cheers for our lymph nodes. They do what they are meant to do and hang onto what they absorb as long as they can! Unfortunately all of mine have gone on one side but there’s plenty more around the body to direct the ‘whatever’ to.
I hope your treatment goes well and you soon feel you’ve got your body back,
