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: bleeding from rectum major surgical or invasive procedure: low anterior resection history of present illness: the patient is an 89-year-old male who presented on with blood per rectum, which prompted a colonoscopy. a circumferential tumor was found 10 cm from the anal verge and a biopsy showed invasive adenocarcinoma, which was moderately differentiated. the plan was for resection, but it was postponed as the patient was anemic and had an episode of chf. the patient underwent transfusion with 3 units of prbc's and diuresis for his chf, and was discharged 3 days later. the patient underwent radiation therapy as well as neoadjuvant chemotherapy and now presents for definitive treatment for his rectal cancer. past medical history: the patient has a history of childhood polio hypertension bph anemia basal cell skin cancer difficulty hearing cataracts rectal cancer social history: the patient denies alcohol or tobacco use family history: significant for brothers who are deceased from rectal cancer physical exam: at presentation, the patient is a pleasant elderly gentleman. there is no cervical, axillary or groin lymphadenopathy. his pupils are anicteric. his heart rate is regular, normal rhythm. no murmurs, rubs or gallops. his lung exam reveals scattered rhonchi diffusely. his abdominal exam, his abdomen is soft, nondistended, and nontender. he has got some weakness of his right leg and some atrophy associated with his childhood polio. pertinent results: 04:35am blood wbc-4.3 rbc-3.85* hgb-11.3* hct-33.0* mcv-86 mch-29.4 mchc-34.3 rdw-14.5 plt ct-116* 11:19am blood glucose-140* urean-38* creat-1.0 na-139 k-4.0 cl-105 hco3-30* angap-8 brief hospital course: the patient was admitted to the hospital on and was evaluated by cardiology prior to procedure. he was prepared the night before with a bowel prep and hibiclens scrub to his abdomen, as well as iv flagyl and cefazolin for prophylaxis. the patient was taken to the operating room that day, where he underwent a low anterior resection. the patient required 1 unit of prbc's intraoperatively. during the case, metastases to the liver were noted. - drain as well as a feeding j-tube were place. the post-operative course was complicated by acute episodes of confusion and by episodes of rapid atrial fibrillation and hypertension. on pod#1, tube feedings were started via the patient's j-tube. on post-operative day #2, the patient experienced bouts of rapid atrial fibrillation, which required iv metoprolol to control. on post-operative day #3, the patient received iv lasix for diuresis, which he responded to well. he also began working with the physical therapists and was able to sit up to chair. on post-operative day #4, the patient was started on zestril for hypertension. on the night of post-operative day #4, the patient became acutely confused and removed his - drain. later that night, the patient's telemetry alarm went off secondary to tachycardia to 160 bpm. the patient was found breathing rapidly and was unresponsive to stimuli. he was found to have an oxygen saturation of 60% on 2lnc, which improved to greater than 90% on a non-rebreathing face mask. the patient became more responsive, and was immediately transferred to the icu for a chf exacerbation. chest x-ray at the time demonstrated bilateral pleural effusions, and lasix was given. a right internal jugular central venous line was placed and a right thoracentesis was performed, at which time 1.5 liters of pleral fluid were drained. the patient was agressively diuresed in the icu, where his cardiac status was closely monitored. on pod#8, the patient had an unwitnessed fall from his bed. though he was uninjured, he was monitored closely and a sitter was placed at bedside. the patient was medically stable the following day, and was sent to the floor. he was evaluated by the hepatic surgery team as well as the medical oncology team, though no consensus was reached during his hospital stay as far as what treatment, if any, will be necessary for his metastatic disease to his liver. following transfer to the floor, attention was turned to agressivley rehabilitating and feeding the patient. the patient worked with the physical therapists, ate regular meals and tolerated tube feeds at night without any incidents or episodes of confusion. on post-operative day #12, the patient is now stable for discharge to an extended care facility. medications on admission: 1. lasix 40 mg p.o. q.d. 2. k-dur 8 mg p.o. q.d. 3. atenolol 25 mg p.o. q.d. 4. procrit 40,000 units 1 tablet q.d. 5. iron sulfate. discharge medications: 1. lisinopril 2.5 mg tablet sig: one (1) tablet po once a day. disp:*30 tablet(s)* refills:*2* 2. tamsulosin hcl 0.4 mg capsule, sust. release 24hr sig: one (1) capsule, sust. release 24hr po hs (at bedtime). disp:*30 capsule, sust. release 24hr(s)* refills:*2* 3. metoprolol tartrate 50 mg tablet sig: one (1) tablet po bid (2 times a day). disp:*60 tablet(s)* refills:*2* 4. aspirin 81 mg tablet, chewable sig: one (1) tablet, chewable po daily (daily). disp:*30 tablet, chewable(s)* refills:*2* 5. furosemide 20 mg tablet sig: one (1) tablet po daily (daily). disp:*30 tablet(s)* refills:*2* 6. zinc sulfate 220 mg capsule sig: one (1) capsule po daily (daily). disp:*30 capsule(s)* refills:*2* 7. docusate sodium 100 mg capsule sig: one (1) capsule po bid (2 times a day). disp:*60 capsule(s)* refills:*2* 8. pantoprazole sodium 40 mg tablet, delayed release (e.c.) sig: one (1) tablet, delayed release (e.c.) po once a day. disp:*30 tablet, delayed release (e.c.)(s)* refills:*2* discharge disposition: extended care facility: healthcare center -
