Atypia means different things when used by different pathologists. The current lesion does need to be re-excised--moderate atypia usually implies wanting to be certain that it's all out.
I continue to be perplexed by questioners who send me their lab tests and ask me what they mean. Lab tests have to be interpreted in light of the clinical condition--that means by the doctor who ordered them. If you're skeptical of that doctor's opinion, perhaps you should find another doctor you trust. Interpreting biopsy reports out of context is likely to lead to distortion and confusion.
