Lump in my breast

Last week I noticed a lump in my breast. I am only 27 and 16 weeks pregnant. Freaking out, I did some research and found that a lump during pregnancy is not all uncommon. It could be a cyst or a clogged milk duct.. I've been to two doctors now who can't confirm what it is and now they are sending me to a breast disease specialist. Not the words I want to hear!! Anyone else have experience with a lump during pregnancy? I'm not even sure what would happen when they understand what it is, surgery? Medication? Scared for the health of my baby too...
