Understanding Chest Density After Breast Cancer: What to Expect

Question
My friend is very concerned as she has been told she has density on the chest.  She has made a full recovery from breast cancer a few years ago, a former smoker and she has suffered from coughs and loss of voice over the past year.  She has just had some x-rays done and was told about the finding of the density.  She now has to have a CT scan.  Is this something to take very seriously as she is concerned cancer has returned but no one will offer any advice at this stage.

Answer
lee;

more or less there having a hard time seeing with just an x-ray,so now they need to have a CT scan to see more clearly.
it doesnt mean she has more cancer at all.

so she needs to relax.

example; like when its foggy,you can see clearly ahead of you.
