Is a continuous irrational in upper stomach in the middle that is there all day everyday a symptom of stomach cancer please help?

Gastric cancer. Would be very unlikely with your age and symptoms. Gastritis is a possibility and anxiety can be a complicating factor as well. A visit to a gastroenterologist should help work this issue out.
Unlikely but.. Unlikely to be stomach cancer but you definitely need to be seen by a doctor to figure out what is causing the pain. Maybe acid reflux, an ulcer, or many other things. Please seek medical advice.
