Large non mass asymetric enhancement of palpable area breast pain both nipple reddish with yellow crust image biopsy benign tissue missed cancer?

I do not know: But a recommendation would be to see a breast specialist to assure you get a second opinion and know then that you definitively do not have a more serious issue.

The level of: suspicion of non mass enhancement depends on its distribution/enhancement pattern, it could be as low as a 5-10% chance of malignancy, so a benign result in that case would be expected. Also, not all benign results are equal, and the benign path finding must be sufficient to explain the imaging finding(concordance). So there is really not enough info to answer your question with any confidence.
