Bad news at anatomy scan

We went to our anatomy scan yesterday at 18w6d and we were told there is a mass in the baby's chest and her heart is pushed to the right. The doctor gave us a few options as to what it could be, including ccam or a teratoma, but didn't really give us any answers. The doctor also said it looked like her stomach was larger than normal and said this could be a diaphragmatic hernia. We are scared out of our minds and were told all we can to is wait and see what happens.

Has anyone been through this and have advice or information they could share? Any little bit would be appreciated
