I recently had a CT scan. It said I have an umbilical hernia, wedge on lungs, and enlarged liver. Mother if five. What is this?

Need to see it. Need to see the report and images to advise on something like this. The real question is why the ct was ordered (what were they looking for)? This is a conversation you should really be having with your doctor that ordered the ct. If you don't have someone to speak with about it, consider finding one and take a copy of the images with you so they can be looked at.
CT. Umbilical hernia is a defect of the wall of your abdomen around the umbilicus. Wedge in your lung may mean that part of your lung doesn't get enough air and has collapsed; enlarged liver is just that enlarged. See your doctor that ordered the ct and discuss it with him.
