When you’re living with lung cancer you will probably hear many terms – bronchus, bronchi, bronchiolesalveolimediastinum, and more. And unless you’ve studied human anatomy, what’s described can be a mystery.

At first glance, knowing what these terms mean seems trivial. Why do you need to understand anatomy when you already have an overload of information to process? But there are times it can be helpful. For example:

  • Why is your cancer inoperable, or if operable, why are they recommending a certain procedure?
  • Why do some positive lymph nodes indicate one treatment and other positive lymph nodes another (for example, mediastinal nodes vs nodes adjacent to your tumor vs nodes above your color bone?)
  • Why is your cancer causing pain – or not?
  • Why can’t they – or can they – do a biopsy during abronchoscopy?

You may not be interested in any of these terms now, but in case questions come up a thorough glossary is available:
