I have been seeing a onocologist for almost 3 years now. My wbc first started out at 15 then kept climbing all the way to 28. Here recently it has been holding steady around 12, but now for the first time I have test positive for ANA. I go to see a rheumatologist soon, but after 3 years of seeing specialist in concerned they will not find anything like the onocologist and G.I. Specialist. What could this be?
