2. recognize the imaging modality considered the standard of diagnosis for tracheobronchial tree tumors
3. learn the classifications of tracheobronchial tree tumors
4. identify symptoms of primary tracheobronchial tree tumors
5. realize how common it is to find squamous cell carcinoma in this part of the body
6. recognize the age group of patients diagnosed with tracheobronchial squamous cell carcinoma
7. learn the tracheobronchial tree tumor associated with habitual cigarette smoking
8. know how much more frequently squamous cell carcinoma affects men than women
9. identify where squamous cell carcinoma tends to form in the tracheobronchial tree
