My lab work shows sed rate 25 crp 27.8 im worried if it can be cancer ??would it be way higher if so ? or it can be something else ? tested negative for ana ?any advice what it can be ?what can cause it to be in. those numbers?

CRP and erythrocyte sedimentation rate (ESR, "sed rate") are markers of inflammation. There must be a hundred or more conditions that could be responsible; it isn't possible to know without a lot more information. Cancer might do it, but that's a lot less likely than various infections and immunologic conditions. Keep working with your doctor; or see an internal medicine specialist. Good luck.
