Gastric Cancer: Understanding the Silent Threat
Gastric cancer, also known as stomach cancer, is a serious and often underrecognized disease affecting thousands worldwide. Despite advances in medical research, gastric cancer continues to pose significant health challenges due to its typically late diagnosis and complex management. This article explores the causes, symptoms, risk factors, treatments, and awareness efforts surrounding gastric cancer, with a special focus on Gastric Cancer Awareness Month and the institutions leading the fight against the disease.

What is Gastric Cancer?
Gastric cancer originates in the stomach lining, typically in the mucosa. It begins when cells in the stomach undergo genetic mutations, causing them to grow and divide uncontrollably. Over time, this can lead to tumor formation. If not detected early, gastric cancer can spread to nearby organs such as the liver, pancreas, and esophagus or metastasize to distant parts of the body.
Types of Gastric Cancer
- Adenocarcinoma: The most common type, originating in the glandular cells of the stomach lining.
- Gastrointestinal Stromal Tumors (GISTs): Rare cancers starting in specialized cells in the stomach wall.
- Lymphomas: Cancers originating in the immune system cells located in the stomach.
- Neuroendocrine Tumors: Rare tumors affecting hormone-producing cells in the stomach.
Symptoms and Early Warning Signs
Gastric cancer is often called a "silent killer" because early symptoms can be vague or mistaken for common digestive issues. Some of the initial signs include:
- Persistent indigestion or heartburn
- Loss of appetite or feeling full after small meals
- Unexplained weight loss
- Nausea and vomiting
- Fatigue
As the disease progresses, symptoms may include:
- Blood in stool or vomit
- Severe abdominal pain
- Difficulty swallowing
Risk Factors and Causes
Several factors contribute to the risk of developing gastric cancer:
1. Infection by Helicobacter pylori
Chronic infection with H. pylori bacteria is a significant risk factor, linked to inflammation and ulcers in the stomach lining.
2. Dietary Habits
Consuming diets high in smoked, pickled, or salted foods and low in fresh fruits and vegetables increases the risk.
3. Lifestyle Factors
Smoking and excessive alcohol consumption are known contributors.
4. Genetic and Family History
Individuals with a family history of gastric cancer or genetic mutations such as hereditary diffuse gastric cancer (HDGC) syndrome face higher risks.
5. Medical Conditions
Conditions such as chronic gastritis, pernicious anemia, and gastric polyps can elevate the risk.
Diagnosis
Diagnosing gastric cancer typically involves a combination of:
- Endoscopy: Visual inspection of the stomach with a flexible tube equipped with a camera.
- Biopsy: Removal of tissue samples for microscopic examination.
- Imaging Tests: CT scans, X-rays, and PET scans help determine the extent of the disease.
- Blood Tests: Identifying markers and signs of anemia or infection.
Treatment Options
Treatment for gastric cancer depends on the stage and type of cancer:
1. Surgery
- Partial Gastrectomy: Removal of a portion of the stomach.
- Total Gastrectomy: Removal of the entire stomach and reconstruction of the digestive tract.
2. Chemotherapy
Often used before or after surgery to shrink tumors or eliminate remaining cancer cells.
3. Radiation Therapy
Used to target and destroy cancer cells in specific areas.
4. Targeted Therapy
Medications such as trastuzumab target specific proteins in cancer cells, offering a more focused treatment approach.
5. Immunotherapy
Emerging therapies help the immune system identify and attack cancer cells.
Gastric Cancer Awareness Month
November is Gastric Cancer Awareness Month, a time dedicated to raising awareness, promoting early detection, and advocating for better research and treatment. This campaign aims to educate the public on the symptoms, risk factors, and importance of timely medical intervention.
The Campaign Color: Periwinkle Blue
Periwinkle blue is the symbolic color of Gastric Cancer Awareness Month. Wearing this color during November signifies support for patients, survivors, and ongoing research efforts.

The Importance of Awareness
Awareness campaigns such as Gastric Cancer Awareness Month play a critical role in combating the disease. Early diagnosis dramatically improves treatment outcomes, and public education can help individuals recognize warning signs and seek timely medical care.
By supporting awareness initiatives and contributing to research efforts, we can pave the way for improved diagnostic methods, more effective treatments, and ultimately, a cure for gastric cancer.
