Gastric Cancer: Symptoms, Risk Factors, Treatments, and Preventative Measures

Cancer is a disease that is defined by the rapid creation of abnormal cells that grow uncontrollably and spread throughout the body. The human body is made of trillions of cells; usually, when these cells grow old or are damaged, they are replaced by new cells. However, sometimes, abnormal and or damaged cells grow and multiply instead of new healthy cells during the cell division process.

According to the American Cancer National Institute, cancer is a genetic disease that can occur either due to error during cell division, damage to the DNA by our surroundings or due to genetic disposition to the disease. Gastric cancer or stomach cancer refers to the abnormal growth of damaged cells in the stomach. Gastric cancer and other gastrointestinal issues require medical attention from specialists called gastroenterologists.

If you are experiencing symptoms discussed in the following segments, you can search for a gastroenterologist in Madhapur and visit a famous gastroenterologist in Hyderabad today.

The wall is made from 5 layers of tissues and muscles. These are-

1.      Mucosa

2.      Submucosa

3.      Muscularis propria

4.      Subserosa

5.      Serosa

The stages of stomach cancer are determined by how far cancer has spread through these different layers. Adenocarcinomas are the most common type of cancer. Lymphomas, gastrointestinal stromal tumors, carcinoid tumors, and hereditary diffuse gastric cancer are rare types of stomach cancer.


Adenocarcinomas are the most common type of stomach cancer. Adenocarcinomas are of 2 main types- Intestinal type and Diffuse type.

·         Intestinal type- Intestinal adenocarcinoma is a type of cancer that grows slowly and can be treated with therapy drugs.

·         Diffuse Type- Diffuse adenocarcinoma grows faster than the intestinal type, is more aggressive, and spreads to other body parts more quickly. However, it is less common than intestinal adenocarcinomas.

Symptoms of adenocarcinomas

You must consult a gastroenterology doctor in Hyderabad or a gastro doctor in Hyderabad if you are experiencing the following symptoms-

·         Loss of appetite

The lymphatic system is a system of organs that stores and produces white blood cells that fight infections and other foreign invaders. Lymphoma is the cancer of the lymphatic system. Mucosa-Associated Lymphoid Tissue Lymphoma is cancer that begins in the stomach. MALT Lymphoma is a slow-growing lymphoma that can usually be detected in its earliest stages. If the cause of MALT lymphoma is a bacterial infection caused by Helicobacter Pylori, then the lymphoma is treated with antibiotics.

Gastrointestinal Stromal Tumors

Gastrointestinal Stromal Tumors is a type of stomach cancer that forms in the stomach lining, which is called ‘Interstitial Cells of Cajal.’ Gastrointestinal stromal tumors are a rare type of stomach cancer whose symptoms include- blood in stool, blood in vomit, abdominal pain, abdominal swelling, loss of appetite, and weight loss. Consult a gastro doctor in Hyderabad if you have the above symptoms. GISTs can be treated with surgery, chemotherapy, radiation therapy, and targeted therapy.

Carcinoid Tumors

Carcinoid tumors are a rare type of stomach cancer that starts in the stomach’s hormone-producing cells. They rarely spread to other organs. They can be treated with surgery, chemotherapy, and radiation therapy.

Hereditary Diffuse Gastric Cancer

This is a genetically passed down type of stomach cancer. Although this kind of cancer is rare, the mutation associated with hereditary diffuse gastric cancer can be detected during genetic testing. Symptoms of HDGC include- loss of appetite, nausea, vomiting, stomach pain, and difficulty swallowing. HDGC can be treated with surgery and chemotherapy.
