Thanks guys. I did have a mammogram, but it was two years ago. They said my breasts were to dense to see into clearly and there was a mass. I ended up doing an ultrasound and MRI which led to them saying, "weird, this is unusual, but unlikely cancer." I'm not really looking forward to that. I ordered the MRI report and it said it may have been that my ducts were prepared to make milk even though my youngest had been weaned for two years.
