I have been to the hospital twice and my family doctor once, and they say I have Gastritis. I have not had any tests done yet, but I just seen my Gastroenterologist today, and he wants me to have an Endoscopy done. Lately I have had a full/heavy brick like feeling in my stomach, with a little burning at times. I am terrified of the possibility of cancer. I do not have a family history of any cancer and I am 24 years old. Never smoked and not a drinker. Could this be cancer? What are my chances of it? I try to stay positive but always think the worst. Can anyone shed some light on this situation for me?
