What does my TI-RADS or biopsy result mean?
TI-RADS describes ultrasound features of a nodule. Bethesda classifies a sample obtained by biopsy. These are different systems, and neither is, by itself, a cancer stage.
For an ultrasound, look for the category and the nodule size. For a biopsy, look for the Bethesda category. An indeterminate result calls for discussion of the options; it does not confirm cancer.
Questions for your appointment
Does my report use ACR TI-RADS or another system? What is my Bethesda category? Should we repeat the biopsy, consider molecular testing or discuss surgery?
