One of the characteristics of this life-threatening disease is that it is diagnosed by its symptoms rather than a regular medical checkup. Unfortunately, in its early stages, this disease does not show any symptoms, so it only comes to a doctor’s attention when it has reached an advanced state; this makes its effective treatment much more challenging. The fact that when symptoms do appear, they can easily be confused with other minor complaints exacerbates the problem. Patients often do not realize they have any reason for particular concern. They tend to ignore these symptoms and not cease medical advice until it is too late.

1. Difficulties swallowing food

Problems swallowing are a key sign that must be taken very seriously. Usually, the issues begin with solid foods and afterward, they start to appear while drinking liquids. Doctors record that initially, patients tell them that it has become hard for them to eat bread or meat. This happens when the tumor in the esophagus has reached a side where it starts to block this passageway. If someone finds themselves in this situation, they need to consult a gastroenterologist. If they suspect that this is a serious problem they will carry out an endoscopy.
