Subject: viral precursor for some lympho cases (clumps)
To: ferrethealth@smartgroups.com
Message-Id: <a05200f0aba26d339dc1c@[10.0.1.40]>
I had some very kind sympathy notes. (Thank you for sending the ones
without health content to me privately.) My old server is glitchy and
I find that soem of my thank you notes to people in reply to their
sympathy notes are coming back to me. Please, forgive me if the
server does this; we are switchiing so are ina sort of netherworld
right now. I did try.)
Do remember that lymphoma can occur NOT in clumps, too, and the
likely viral precursor is for the clump situation.
Some of the notes asked for more info on lympho clumps and possible
viral precursors so i searched. I am sure that i have missed some
but these past FHL posts should help you:
