What causes stomach pain in esophageal cancer

We all know that progressive dysphagia is the first symptom of esophageal cancer, but most patients will also experience other adverse symptoms, such as pain, in the middle and late stages. Many patients do not understand this symptom. Next, let's take a look at the experts' introduction to the causes of stomach pain in esophageal cancer.

Reason 1: Cancer cell growth

The rapid growth of cancer cells has a great impact on the patient's body, which is very different from benign tumors. The malignant tumor cells of this disease grow in an invasive manner, and their tissue cells are different from normal tissues in morphological structure, functional metabolism, biochemical changes and enzymology. Therefore, it is easy to invade adjacent tissues and organs, destroy tissue structure, and change their functions. If the nerves and blood vessels at the site of cancer cells are affected, pain may occur.

Reason 2: Cancer cell spread

Through experiments, it has been observed that cancer cells can infiltrate adjacent tissues and organs at the primary site and spread to other parts through the vascular system, lymphatic system, etc. Once the tumor invades blood vessels, nerves, and organs, it can easily cause functional changes in the corresponding tissues and organs, resulting in pain.

Reason 3: Substances produced by cancer cell tissue

Experts say that some cancer cells produce hormone-like chemicals or decomposition products of metabolic and necrotic tissue, which can easily become infected, causing physiological and pathological changes in the nerves and resulting in pain.

Reason 4: Psychological aggravation of pain

This disease will inevitably cause a certain amount of psychological pressure on patients, which may lead to depression and anxiety in patients, which will aggravate the deterioration of the overall condition and create a vicious circle. This is the main cause of pain.

The above is an introduction to the causes of stomach pain caused by esophageal cancer. After understanding the causes of the pain, patients can effectively eliminate their doubts, reduce psychological pressure, know that this is not an aggravation of the disease, and let go of their mental burdens.
