What sort of cysts and tumors have you had ? I can tell you that I've read that EBV can be associated with numerous cancers.
Over tha last few years I have had cyst and/or tumors several locations in my abdomen and bones, some lg.-few in. and some sm.- 1cm. For the most part the are scatter in lower torso ie: retroperitonium, bladder, in and out of ovaries (now removed), uterus (also gone now), and also my bones? I've had several of the larger growths removed, I didn't see the sense in bothering with the smaller ones-didn't want an added surgery- until this last surgery when they took both ovaries because one of the smaller tumors "looked highly suspicious", yet everything ended up coming back benign. I was told the one 'in' my hip bone will be addressed when I have my hip replacement, I also have AVN and have been procrastinating hip replacement. Anyway, these growths just apear from no-where and keep getting noticed when I have my bone scans/mri's/ct scans. My Dr. sais I just cystic, he really doesn't have an answer, and for the most part I really don't care, until they wanted my ovaries, plus they have caused some side effects-like bladder issues etc. Thank you for your insight.
