 Stomach cancer is often misdiagnosed as acid reflux, indigestion, or an ulcer. Because of this, most stomach cancers are found in late stages when there are little to no options left for treatment. I'm not a healthcare provider, just a young mother who lost her husband to this cruel disease. If you or a loved one is experiencing persistent symptoms that can be really common, such as heartburn, having trouble swallowing, or indigestion, you should seek help with a gastroenterologist as soon as possible.
