Recently, I have been suffering from epigastric pain. I also have symptoms of lower back pain. The doctor asked me what symptoms I have? Thank you doctor!

I experienced symptoms such as abdominal pain in the epigastrium, weight loss, loss of appetite, difficulty swallowing, black stools from time to time and sometimes abdominal pain and could not sleep. Is epigastric pain accompanied by loss of appetite a sign of stomach cancer?
