Hi guys. I'm soo scared right now. I went to a cardiologist. Long story short she thought I could have a blood clot in my lung. I had a CT scan done and they found a nodule in my lung. I have a nodule in my thyroid, in my lung, and a lymph node that is hard and palpable in my breast. This is all on my right side. Anyone else have this? Normal? They want me to do a PET scan. Should I be concerned?
