Went to my doc, showed her two lumps under my left collar bone. She said they were not to worry about, swollen lymph nodes but to let her know if they for bigger. 6 weeks later I called her as they had almost doubled in size. I had also found more lumps. I went back, all of my infraclavicular lymph nodes are enlarged. She sent me to a surgeon, he says it is just a sebaceous cyst and nothing to worry about? My primary doc is sendin me for a second opinion and for a mammogram. I am not sure what to think, or who I should believe.
