Hello and welcome to the forum. I greatly apologize for the slow response to your situation. Is there any follow up? I assume you have by now had your biopsy to determine if this is cancer. Please let us know the outcome and we will go from there. A hypechoic mass is NOT always malignant. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4644748/ We are hoping this is the case for you. Please let us know.
