I had a mammogram 4 wks ago and went to my surgeon for the results and he said the report looked great. Although he found a "mass or lump" in the right breast when he did the exam after the mammogram. He said he felt like it was just breast tissue and wanted to recheck in 6 months. I wanted an ultrsound but he would not agree. Do u feel 6 months is to long? I do. I'm very scared. No family history of breast cancer. I want to know what it is. Can it progress over 6 months to far?
