I found a lump during my self exame. When I went to the doctor she felt it also. She sent me in for a mamogram and an ultrasound. When she called with the results she said that the ultra sound showed nothing and that I had a fibroid cyst. She didnt say what the mamogram found... I was under the impression that ultrasounds found the fribroid cysts. And I cannot figure out how something the doctor and myself have both felt is not visable. The lump has since gotten large and sort of sread out. Should I get a second opinion?
