Consider the following medical report that includes the patient's historical health records. Use it to predict the disease that the patient is high likely exposed to. 

 Medical Report: technique: ct chest with iv contrast. ct of the airway was performed during dynamic aspiration. 100 cc of optiray was administered iv for patient's history of allergies. ct chest with iv contrast: soft tissue windows reveal supraclavicular lymph nodes on the right side, measuring approximately 16 mm in short axis. there is bulky right paratracheal lymph nodes, measuring approximately 2 cm in short axis. a large mass is present in the right hilar measuring approximately 4.4 x 3.4 cm in size. there is associated right hilar and subcarinal lymphadenopathy. the right upper lobe bronchus is obstructed. the patient is status post stent placement in the bronchus intermedius. soft tissue density is noted in the stent. considering the proximety of the stent to the adjacent tumor this most likely represents tumor invasion rather than granulation tissue. the cross sectional area of the stent is stenosed by approximately 45%. the right pulmonary arteries are encased by the hilar mass, stretched and narrowed, but appear patent. right middle lobe and right lower lobe bronchi appear patent. trace bilateral pleural effusions are noted. lung windows reveal a calcified granuloma in the right lung base. diffuse air space ground glass opacifications are present bilaterally, left greater than right. post obstructive atelectasis of the right upper lobe is seen. expiration images demonstrate no evidence of tracheobronchomalacia. the patient also has an abdominal ct on the same day. please see the abdominal ct for the full report for abdominal findings. bone windows reveal no significant abnormalities. expiration images reveal no excessive airway collapse that is suggestive of tracheobronchomalacia. impression: (over) 1:27 pm ct trachea w/c & w/recons; ct 100cc non ionic contrast clip # reason: squamous cell ca,s/p stent,assess airway involvement of tumor field of view: 40 contrast: optiray amt: 100 ______________________________________________________________________________ final report (cont) 1. large right hilar mass obstructing the right upper lobe bronchus with post obstructive atelectasis of the right upper lobe. mediastinal lymphadenopathy is also noted. 2. the patient is status post stent placement in right mainstem bronchus and bronchus intermedius. soft tissue density is present within the stent, with associated luminal narrowing. this may represent tumoral involvement, and less likely represents granulation tissue or secretions. note is also made of thickening of the wall of the right mainstem bronchus extending to its origin from the carina. the right middle lobe and lower lobe bronchi are patent. 3. diffuse ground glass opacities in the lungs, left greater than right, which may represent infectious pneumonitis, drug reaction or hypersensitivity pneumonitis. less likely this could represent lymphangetic carcinomatosis. addendum: multiplanar and 3-d images were reconstructed and reviewed in conjunction with the axial images. they confirm the presence of right upper lobe bronchial obstruction. procedure: continuous invasive mechanical ventilation for less than 96 consecutive hours other intubation of respiratory tract endoscopic excision or destruction of lesion or tissue of bronchus diagnoses: pneumonia, organism unspecified subendocardial infarction, initial episode of care other pulmonary insufficiency, not elsewhere classified obstructive chronic bronchitis with (acute) exacerbation other specified cardiac dysrhythmias malignant neoplasm of upper lobe, bronchus or lung other and unspecified alcohol dependence, unspecified alcohol withdrawal malignant neoplasm of main bronchus 

Answer: The patient is high likely exposed to
