A coworker of mine went on a vacation a year ago telling everyone that he would be gone a week so we were all surprised when he showed up on the following Wednesday. After we heard the story, I was floored.
He had taken off early Saturday morning with his family and arrived in North Carolina on Sunday evening. After supper however, he started feeling poorly and his chest began hurting. On Monday morning, it still persisted so he made a doctor's appointment which included some x-rays and culminating in the doctor asking for his wife to come into the patient room so that he could tell both of them together the diagnosis. He knew that couldn't be good.
The doctor said that the x-ray had shown that cancer was scattered clear through his torso and that he probably only had a matter of weeks to live. The doctor advised him to drive back to Iowa immediately to get his affairs in order and to schedule an appointment with his doctor to get on some sort of pain medication. My coworkers and his wife broke the news to their two kids that he was going to die in a matter of weeks and that they needed to drive back home. He didn't say how it went but I imagine it was one of the longest drives he has ever taken. The only good thing was that in the middle of all the tests at the hospital, his pain had disappeared completely.
Back home, his doctor is stunned to hear the news and ordered more x-rays. They came back and the doctor said that my co-worker was completely normal and that there was no sign of any cancer what-so-ever. He theorized that the x-ray machine at the hospital in North Carolina hadn't been working properly and thus the misdiagnosis. Further more, he said that the pain had probably been just the result of a case of indigestion.
