Hey doc. I m petrified I have some sort of cancer. I ve been a smoker for 9 years, am 26 years old. Recently quit smoking (two days clear). Have had some issues breathing as of tuesday. Have been to the ER where they did a chest x ray but I recently found out I have esophageal cancer in my family. I have chest pressure and it feels like i swallowed something ( almost as if I m about to cry, that knot in your throat you get) and recently have been burping a lot . a few times bile would come up.
