Candi,
I understand how scary this can be. Trust your instincts. After faithfully performing monthly self exams and annual mammograms, I found a small lump. I had two mammograms, two ultrasounds, and was told by three MD's it was nothing. I insisted the lump was NOT there before. I had a surgical biopsy and... it is cancer, IDC. I then had a PET scan which came back negative - exept for the one breast - and a MRI which showed additional cancer in the affected breast. I opted for a bilateral mastectomy and will have it this week. I am hoping for the best but... TRUST YOUR INSTINCTS. No one knows your body better than you. I will pray for you tonight.
