The gastrointestinal stromal tumor is a rare tumor type of soft tissue sarcoma and mainly affects the digestive tract of the body. It causes Cajal intestinal cells to grow a cancerous tumor that will affect the absorption and breaking down of food in the gastrointestinal tract. This type of tumor is mainly associated with the stomach and small intestine organ of the digestive tract. This tumor affects the nerve cells present in the lining walls of the digestive tract and changes the DNA of cells which controls the digestive process and allows absorption, movement of food in a gastrointestinal tract. The tumors grow in nerve cells are part of the autonomic nervous system which regulates the body functions. This tumor primarily found in people between age 40 and 70 years and very rare in children.
Causes of Gastrointestinal Stromal Tumor(GIST)
The cause of gastrointestinal stromal is the change in DNA or genetic mutation in KIT and PDGFRA cells. This genetic mutation affects the growth, changes, or repairing of normal cells and helps abnormal cells to grow, divide, and multiply the normal cells which will impact on the immune system. But most of the genetic mutation is not inherited and changes appear for no reason are called sporadic.
The KIT gene helps to produce a protein that is responsible for proper growth, repair of cells, and replaces old cells with the new cell. This gene is normally inactive but due to tumors, it remains active continuously to grow and divide cells. The 90-85 % cases of gastrointestinal tumors have occurred due to changes in the DNA of the KIT gene.
The PDGFRA gene starts to make too much protein due to cancerous cell have damaged the DNA of it. The excessive production of protein impact on the normal cell and restrict the growth of the normal cell.
Few cases are not linked with the KIT and PDGFRA gene mutation and there are other risk factors which can cause gastrointestinal stromal tumor is as follows.
Risk factors and less common causes

The endoscopy and colonoscopy tests will be used to know the tumor is cancerous or not. These tests also help to know the tumor in abnormal locations which is unable to detect in by imaging tests.
Chemotherapy and radiation therapy are the conventional and most used methods to treat cancer. In chemotherapy drugs are injected into the bloodstream which travels and destroys the cancerous cell spread to other surrounding organs. In radiation therapy, high energy beam rays are used to kill and destroy the cancer cells.
The targeted drug therapy is the most common and effective therapy in order to treat gastrointestinal tumors.
