Well come to HCM
Thank for asking
Your query being appreciated, of course it is the cyst but to differentiate it for malignancy biopsy
is must, else it can be considered benign cyst
, even the blood worked up result will not different the type of cyst it can only shows the infection if it is ever there, the given blood test
result is not the diagnosis criteria for malignancy, instead of depending upon the blood test better to discuss for biopsy with your surgeon hope this information helps.
