stomach pain and nausea

Six weeks ago I started to experience constipation with slight nausea.The constipation has gone away but I now have pain in my left, middle, and right side with nausea for three weeks.The pain is the greatest and most frequent on the left side.I have not had a fever or vomited. The pain does move to the center and to the right side at times. The pain and nausea seem to be worse after I eat.I am white, 41 years old, non-smoker and non-drinker, who is normal weight. Also, at times my stool is looses.I had a colonoscopy two years ago that was fine. Does this sound like stomach cancer? Does anyone have an experience like this?
