Before I got cancer, I used to collect $2 bills. They were rare, and I thought that meant they were lucky, but rare and lucky are not the same thing. In the beginning of the spring semester in 2014, I began suffering from severe pain and fatigue, which I originally chalked up to overwork. I had an endoscopy. A few days later, my gastroenterologist called to tell me that my biopsies had tested positive for stomach cancer. The chance of getting this disease was approximately 0.9 percent.
