So I have to have a breast MRI, my test for cancer came back negative.  The other test results are still pending.  They said I didn't have lymphadema, but that I would always be at risk for it.  They said they did not know what was causing my lymph nodes to be swollen like this.  What is going on??  Why would my Lymph Nodes be swollen and look bad enough that they feel like they need to remove them, with no ability to diagnose the cause???
