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: history of present illness: this is an 84-year-old woman with a one-month history of bright red blood per rectum, blood in stools. patient states that she first noticed a small amount of blood approximately one month ago when she was living in a rehab facility. patient had no history of pain, but had noticed loose stools previous to that point. patient was evaluated by the rehab house officer and managed expectantly. as the problem had not resolved over the following few weeks, the patient was sent for a colonoscope, which revealed a 6 cm circumferentiated mass in her colon. patient denies any fever or chills, weight loss, night sweats, headache, shortness of breath, cough, bloating, dysuria, hematuria, jaundice. patient only endorses positive nausea, but states that she feels well, and denies any current vomiting or abdominal pain. previous medical history: 1. history of cerebrovascular accident with right-sided weakness. 2. hypertension. 3. coronary artery disease status post myocardial infarction. 4. peripheral vascular disease. 5. hypercholesterolemia. 6. degenerative joint disease. 7. myofascial pain syndrome. 8. hypothyroidism. 9. status post orif of the right femur. 10. status post hysterectomy. 11. status post right wrist fracture. 12. depression. medications at rehab: 1. tylenol 650 mg p.o. t.i.d. 2. calcium carbonate 650 mg p.o. t.i.d. 3. captopril 50 mg p.o. t.i.d. 4. premarin 0.625 mg q.d. 5. synthroid 100 mcg q.d. 6. lopressor 50 mg p.o. q.d. 7. zocor 40 mg p.o. q.d. 8. multivitamins, vitamin d, lactaid. allergies: penicillin. physical exam: patient was afebrile. temperature of 98.0, pulse 53, blood pressure of 160/62, and breathing 12 times per minute, and 98% on room air. in general exam, she was alert and oriented times two, not to be place, nonambulatory in no distress. there was no rash, no jaundice noted. heent: there was no lymphadenopathy or thyromegaly appreciated. her carotids ...... 2+ bruit. pupils are equal, round, and reactive. pulmonary: positive for right lower lobe crackles, otherwise were clear to auscultation bilaterally, no wheezes were noted. cardiovascular: regular rate and rhythm, no rubs or gallops, 1-2/6 systolic ejection murmur. abdomen is soft, nontender, and nondistended, no hepatosplenomegaly appreciated. rectal exam was guaiac positive, normal tone. lower extremities revealed no erythema or edema. the patient was admitted to the blue surgical service with dr. as the attending. the patient was placed on iv fluids and scheduled for colonoscopy in the morning. in preparation for possible surgical intervention, the patient was seen by cardiology on , who had recommended an echocardiogram and starting of aspirin. in the preoperative days following the admission, the patient had a chest x-ray, which revealed marked improvement in congestive heart failure with linear opacities towards the lung bases. the patient underwent stress testing on , which revealed an ekg with evidence of a prior myocardial infarction. during the testing there was no st segment changes over the baseline abnormalities. the patient had no anginal symptoms and no ischemic ekg changes. on the following day, , the patient underwent a transthoracic echocardiogram, which revealed mild symmetric left ventricular hypertrophy, an ejection fraction of approximately 45%. there was mild-to-moderate aortic regurgitation, moderate 2+ mitral regurgitation. still in the preoperative operative, the patient underwent a colonoscopy performed by dr. . the colonoscopy revealed a high grade obstruction in the rectum that the scope was unable to pass through it. it was determined that the patient should be worked up for a left colectomy. to further evaluate the mass within the left rectum, the patient underwent a transrectal ultrasound, which revealed a rectal mass with an extension beyond the muscularis propria and therefore considered to be a t3 lesion. there is also a single lymph node along the left lateral aspect of the rectum, which had a dimension of 2.8 mm. over the next couple of days, the patient continued to do well with no complaints and to complete her cardiac workup prior to surgery, the patient underwent a thallium stress test, which revealed a hypokinesis of the inferior wall that was moderate and reversible. on the day of the patient's surgery, , the patient underwent cat scan to further delineate the extent of the mass. the results were as follows: a circumferential enhancing mass noted in the rectum measuring up to 6 mm in thickness. multiple colonic diverticula, enumerable diverticula noted in the sigmoid colon, and resultant in sigmoid wall thickening. on , the patient underwent a low anterior resection, coloproctostomy, feeding jejunostomy. the procedure was performed by dr. and assisted by dr. . there were no complications during the procedure, and the patient tolerated the procedure well. the patient did require a swan-ganz catheter for continuous monitoring of the svo2 and as the patient did require a dobutamine early in the case with a cardiac output dropping from 2.0 to 1.3. the dobutamine stayed at a low dose of 5 mcg/minute. the patient was returned to the recovery room in good condition, and after a brief stay in the pacu, the patient was transferred up to the surgical intensive care unit. in the pacu, the patient continued her recovery. placed on a nitroglycerin drip and with a demerol epidural. the patient's epidural needs to be changed over to a dilaudid/bupivacaine solution for an increase in pain control. from a cardiovascular standpoint, the patient's systolic blood pressure remained high in the 130s-180s, and was controlled with nitroglycerin drip. during her stay in the pacu, the patient was slowly weaned off her nitroglycerin drip for a cuff pressure of less than 170. the patient tolerated this well and there were no difficulties. by postoperative day #3, the patient was completely off her nitroglycerin drip and blood pressure was controlled with iv hydralazine. her j tube was draining a dark green fluid at this time, and tube feeds were started at 1.5 strength impact with fiber at 10 cc/hour. by postoperative day #5, the patient had her epidural removed and pain was controlled only with iv morphine as needed. the patient was then transferred to the floor on postoperative day #5. patient continued her recovery on the surgical floor and did very well. patient had brief episodes of confusion, but these resolved with the presence of a sitter in the room, and constant contact with the nurses. from a cardiovascular standpoint, the blood pressure was well controlled on iv medications. by postoperative day #7, the patient had two bowel movements and the patient's diet was advanced to include sips of clear liquid diet and increase in the tube feeds. the patient continued to do well and was able to tolerate tube feeds at 40 and clears adlib by postoperative day #8. patient was started on soft solids and cycling of her tube feeds in the following days, and then discharged to rehab on postoperative day #10. during the patient's stay in the hospital, the pathology from her surgical procedure was finalized. the results are as follows: 1. colonic mucosal biopsies revealed no convincing features of malignancy are identified. 2. highest node revealed fragment of fibrovascular and adipose tissue, no lymph nodal tissue identified. 3. sigmoid revealed a) diverticulosis, b) no diagnostic abnormalities recognized at the resection of the margins, c) lymph nodes, no evidence of malignancy. 4. resection of rectosigmoid colon revealed adenocarcinoma. the adenocarcinoma was low grade invading through the muscularis propria into the subserosa. in the regional lymph nodes, there metastases in four or more lymph nodes with a total of that were involved. ultimately, the tumor was classified as a t3 n2 mx. the distal metastases were not assessed. discharge disposition: the patient is to be discharged to rehab on . follow-up instructions: the patient is instructed to followup with dr. in weeks. the rehab was asked to please call and make this appointment for the patient. discharge condition: the patient was discharged in good condition: afebrile, tolerating a regular diet and tube feeds without difficulty, voiding and stooling without problems, able to situp and out of bed with assistance. discharge diagnoses: 1. status post low anterior resection. 2. status post jejunostomy tube placement. 3. adenocarcinoma of the colon. 4. diverticulosis. 5. history of cerebrovascular accident. 6. hypertension. 7. congestive heart failure. 8. coronary artery disease status post myocardial infarction. 9. peripheral vascular disease. 10.
