The Medical Terms

The mass in Baby's chest cannot be diagnosed conclusively until it is taken out and examined. The doctors have narrowed it down to two different possibilities: Bronchopulmonary Sequestration (BPS) and Congenital Cystic Adenomatoid Malformation (CCAM). BPS is the more likely diagnosis, but BPS's often have CCAM components as well, so we are likely dealing with both. Wikipedia has definitions of both these conditions, which I thought were consistent with what the doctors told us (from what my muddy brain can remember). It was nice to be able to see the facts spelled out while I was not a completely confused emotional mess.
