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: allergies: patient recorded as having no known allergies to drugs attending: chief complaint: l parotid mass major surgical or invasive procedure: l parotidectomy history of present illness: 72m with h/o l parotid mass. fna revealed malignant cells. pt presents for elective left parotidectomy. past medical history: dm cad s/p cabg h/o atrial fibrillation htn cri w/cr 2.0 h/o scc l leg/r ear social history: occasional etoh, no tobacco family history: nk physical exam: nad eomi, nares patent, oropharynx clear without exudates/erythema l face and neck incision intact without overlying erythema or swelling. neck otherwise flat and soft. cn vii intact to testing pertinent results: 03:48pm glucose-160* urea n-43* creat-1.9* sodium-139 potassium-5.1 chloride-108 total co2-23 anion gap-13 03:48pm ck(cpk)-38 03:48pm ck-mb-2 ctropnt-<0.01 03:48pm calcium-8.5 phosphate-3.1 magnesium-1.7 03:48pm digoxin-1.6 03:48pm wbc-7.3 rbc-4.15* hgb-12.6* hct-37.4* mcv-90 mch-30.5 mchc-33.8 rdw-15.0 03:48pm plt count-159 02:18pm type-art po2-325* pco2-44 ph-7.34* total co2-25 base xs--2 vent-controlled 02:18pm glucose-197* lactate-2.1* na+-137 k+-5.4* cl--106 02:18pm hgb-13.7* calchct-41 02:18pm freeca-1.17 brief hospital course: pt underwent a left parotidectomy. intraoperatively, anesthesia noted that the patient was likely in atrial flutter. he was kept intubated overnight as anesthesia was concerned regarding the need for reintubation as the patient has a h/o of difficult intubation and required a fiberoptic intubation for this operation. postoperatively, he was transferred to the micu where he was electrically cardioverted successfully. he was stable overnight and on pod 1, he was extubated without difficulty. he tolerated po intake, and remained in normal sinus rhythm. on pod 2 he continued to do well and remained in nsr. he was transferred to the floor. cardiology recommended no further interventions for mr. regarding his episode of a-fib/a-flutter. on pod 3, his jp drain was discontinued and he was discharged home in good condition. 1. l parotidectomy -pt did well post operatively -l jp drain removed prior to discharge -cn vii intact -pathology pending 2. a-fib/a-flutter -started intra-op, pt electrically converted in the micu and remained in nsr for the remainder of his hospital stay -cardiology recommended no further intervention above pt's home dose of digoxin and atenolol 3. dmii -bs well controlled during his stay with regular insulin ss and glargine 4. dispo -discharged to home -pt to f/u with dr. medications on admission: digoxin, atenolol, diovan, nitrodur, amaryl, glargine, lipitor discharge medications: 1. oxycodone-acetaminophen 5-325 mg tablet sig: 1-2 tablets po q4-6h (every 4 to 6 hours) as needed for pain. disp:*20 tablet(s)* refills:*0* 2. keflex 500 mg capsule sig: one (1) capsule po three times a day for 5 days. disp:*15 capsule(s)* refills:*0* discharge disposition: home discharge diagnosis: left parotid mass discharge condition: good discharge instructions: please take your antibiotcs as directed. do not drive while taking pain medications. please call the clinic or come to the emergency room if you have fever or increased swelling and pain in your neck. followup instructions: please follow up with dr. in days. call for an appointment. procedure: complete sialoadenectomy diagnoses: unspecified essential hypertension diabetes mellitus without mention of complication, type ii or unspecified type, not stated as uncontrolled atrial fibrillation aortocoronary bypass status atrial flutter chronic kidney disease, unspecified malignant neoplasm of parotid gland
