I am wondering if a person can get adenocarcinoma in the trachea.  My mother had 2/3 of her lung removed 2 years ago after having been diagnosed with Stage 1 adenocarcinoma.  Now she just left an ENT who told her that her trachea is pushed to the side due to some type of undetermined blockage.  A CT scan is scheduled for the 15th.

Summarized question: Can Adenocarcinoma spread to the trachea?
