17. Indigestion and Nausea
Are you a frequent sufferer of indigestion and nausea? This could be a symptom of cancer, especially of the esophagus and stomach.
A single case of indigestion is not anything to panic over. But a doctor should check you out if indigestion and nausea occurs frequently, it occurs suddenly, or if it’s especially painful, and you are over the age of 55. Even if it isn’t cancer it could be still be a sign of something else that is serious and needs to be looked at, like an ulcer.
