Before I was diagnosed with OC, I had had a dry cough for several months. Did anyone else have a cough? My cancer was stage one, just a tiny pink spot on the photo taken during the endoscopy. I had no symptoms of the cancer, just the cough. I'm trying to work out how a tiny pink spot in my esophagus could have made me cough. It wasn't big enough to put pressure on my trachea. Or was there no connection between the two things?
