in Apr2021 he was diagnosed with Colon Cancer; This is a spontaneous report from a contactable consumer (patient)  via the Pfizer sponsored program. This consumer reported different events for different vaccine doses for the same patient. This is one of the two reports.  A 67-year-old male patient received dose 2 of BNT162B2 (Pfizer-BIONTECH COVID-19 Vaccine), via an unspecified route of administration on 22Feb2021 (at the age of 67-years-old) (Batch/Lot Number: EL9264) single, for COVID-19 immunization.

Last year he was sent for a test to determine if he had pancreatic cancer, it was to a specialist in (withheld), the name of the procedure is unknown but they go down into the small intestine with a contrast into the pancreas and as a result of that he got pancreatitis, he lost 50lbs in 6 months getting over that. Prior to the pancreatitis, he has had 2 heart attacks back about a decade ago. He had a triple bypass about 6 years ago 2014 or 2015 the outcome was no problems at all, the only time a cardiologist comes was when he has to be cleared for some other procedure. They have him on Plavix daily dose for a blood thinner. In 2017, he suffered a series of strokes in the back of the brain, that's where the damage was, located in the artery that comes up from brain and forms a Y, there was a blockage in there, an inch of the blood vessel collapsed, there was leakage there and found 3 different spots where there was injury. He had an MRI this year and there was no evidence of stroke activity. The stroke was in Dec2017 and he was not cleared to return to work.

The patient received the first dose of BNT162B2 (Pfizer-BIONTECH COVID-19 Vaccine) on 01Feb2021 (Lot number: EL3247); the patient had zero reactions to this shot. Earlier this year in Apr2021, the patient was diagnosed with colon cancer. In Apr2021 this year, they did a colon resection and removed 12 inches. Also in Apr2021, they referred him to an oncologist because of  his examination, he had a colonoscopy. The surgeon said because this was spotted early, there was no reason for follow up treatment or chemo. The colonoscopy was done in Mar2021 and the doctor was his surgeon. He had actually been doing the colonoscopy's on him for a long time, and the spot that turned into cancer was something he, the doctor, had already been monitoring and was nothing new. It was reported that the spot was noticed way before him receiving his COVID vaccines in Feb2021. Outcome of the event was unknown.  No follow-up attempts are possible. No further information is expected.; Sender's Comments: Linked Report(s) : PFIZER INC-202100999866 same report/patient, different vaccine dose/event
