Hi... Welcome to HEALTHCARE MAGIC.. . I have gone through your query and can understand your concerns... The symptoms that you mentioned in your query could be associated with less serious diagnoses like gastritis or peptic ulcer disease, but you are at greater risk for developing gastrointestinal cancers if you have a family history of the cancers. Early Gastrointestinal (GI) / stomach cancer usually does not cause symptoms. The majority of stomach cancer patients have non-specific complaints, such as: • Indigestion or heartburn • Abdominal discomfort (bloating, belching, gas pains, etc.) • Loss of appetite • Occasional vomiting • Diarrhea or constipation • Unexplained weight loss • Decreased ability to eat a large meal Other less common, yet serious, symptoms are: • Difficulty swallowing • Vomiting blood or blood in the stool As a precautionary measure, you should consult with a doctor and the diagnosis will be made after upper endoscopy with biopsy. Hope this answers your question. If you have any additional questions then please do not hesitate in writing to us. I will be happy to answer your question. Thanks & Regards, Dr.Shiwani
