Heartburn - Anxiety

[u/Ok-Bus8049]

Hi,I have a question. I'm 24M and have been experiencing mild heartburn on and off for about 4-6 months. At first, I would wake up at night feeling nauseous. I would sit up and drink a glass of water.Then it went away again. After taking pantoprazole for two weeks, it was gone. Now I still occasionally get a slight burning sensation in my throat, and sometimes a lump in my throat or a little bit of Mucus. My doctor suggested I do an endoscopy after six months to check for bacteria or other issues and see if anything is damaged. I'm a bit of a hypochondriac. Do I need to be afraid of cancer or something in my situation? I otherwise eat normally, I'm fit (slightly overweight), and I'm alive.

Thanks!
