Explore symptoms, risk factors, and treatment options, discover innovative therapies, and understand the stages of stomach cancer.
1. Understanding What Is Gastric Cancer
Gastric cancer, or stomach cancer, begins in the stomach. The stomach is a muscular sac located in the upper middle of your abdomen, just below your ribs. It receives and holds food and then helps to digest and move it to the small intestine. Gastric cancer can develop in any part of the stomach and spread throughout.
1.1. What Are the Different Types of Gastric Cancer?
There are several types of stomach cancer, with adenocarcinoma being the most common. Adenocarcinomas start in the mucus-producing gland cells of the stomach lining. Less common types include:
- Lymphoma: Cancer that begins in the immune system.
- Gastrointestinal Stromal Tumor (GIST): A rare type of tumor that starts in special cells in the stomach wall called interstitial cells of Cajal.
- Carcinoid Tumor: Starts in hormone-producing cells in the stomach.
Do you have questions about these types? Ask them on WHAT.EDU.VN and get free answers.
1.2. Where Does Gastric Cancer Usually Occur?
While gastric cancer can occur in any part of the stomach, in the U.S., it’s most commonly found in the gastroesophageal junction. This is where the esophagus (the tube that carries food to the stomach) meets the stomach.
1.3. Is Gastric Cancer Curable?
Yes, especially when detected early. Advancements in technology and scientific research have significantly improved treatment outcomes. New cases of stomach cancers have decreased by about 1.5% every year for the last 10 years.
1.4. What Does Gastric Cancer Look Like?
Typically, gastric cancer starts with small changes in the DNA of stomach cells. These changes tell the cells to multiply uncontrollably, leading to abnormal growths called tumors. The appearance can vary depending on the type and stage of cancer.
2. Who Is at Risk for Developing Gastric Cancer?
Several factors can increase the risk of developing gastric cancer. Understanding these risks can help in early detection and prevention.
2.1. Age and Gender
Stomach cancer is more common in older adults, with the average age of diagnosis being 68. About 60% of cases occur in people over 65. Men have a slightly higher lifetime risk than women.
2.2. Lifestyle Factors
- Smoking: Doubles the risk of stomach cancer.
- Diet: A diet high in salty and smoked foods, or low in fruits and vegetables, increases risk.
- Weight: There is a correlation between higher weight and increased risk.
2.3. Medical Conditions
- H. pylori Infection: Long-term infection with Helicobacter pylori.
- Chronic Stomach Inflammation: Long-term inflammation of the stomach lining.
- Gastroesophageal Reflux Disease (GERD): Chronic acid reflux.
- Stomach Polyps: Abnormal tissue growths in the stomach.
- Family History: Having a family history of stomach cancer increases your risk.
2.4. Genetic Predisposition
Certain genetic mutations can increase the likelihood of developing stomach cancer. If you have a family history, genetic testing might be beneficial.

3.2. When to See a Doctor
If you experience any of these symptoms and they worry you, it’s important to see a doctor. They may investigate common causes first or refer you to a specialist like a gastroenterologist or oncologist.
3.3. Why Early Detection Matters
Detecting stomach cancer early significantly improves the chances of successful treatment. Regular check-ups and awareness of symptoms can make a big difference.
4. How Is Gastric Cancer Diagnosed?
Diagnosing gastric cancer involves several steps, starting with a physical exam and review of your medical history.
4.1. Upper Endoscopy
An upper endoscopy involves inserting a thin, flexible tube with a tiny camera through your throat and into your stomach. This allows the doctor to visualize the lining of your stomach and look for any abnormalities.
4.2. Biopsy
If the doctor finds something suspicious during the endoscopy, they will remove a tissue sample for a biopsy. The cells are then sent to a lab for analysis to determine if cancer is present.
4.3. Imaging Tests
- CT Scan: Provides detailed images of the stomach and surrounding organs.
- Barium Swallow: A special X-ray where you swallow a barium solution to help highlight the stomach and esophagus.
4.4. Staging
To determine the extent of the cancer, your doctor may order additional tests:
- Blood Tests: To check overall health and look for signs of cancer.
- Endoscopic Ultrasound: Provides detailed images of the stomach wall.
- PET Scan: Helps detect cancer spread to other parts of the body.
- Laparoscopic Surgery: Involves inserting a camera directly into the abdomen to examine the area.
5. Treatment Options for Gastric Cancer
Creating a treatment plan for stomach cancer involves a collaborative effort between doctors from different specialties. The goal is to develop the best plan for your overall health and well-being.
5.1. Surgery
Surgery aims to remove all of the cancerous tissue and some surrounding healthy tissue. The type of surgery depends on the stage and location of the cancer.
5.2. Chemotherapy
Chemotherapy uses drugs that travel throughout the body to destroy cancer cells. It can be used before surgery to shrink the tumor or after surgery to kill any remaining cancer cells.
5.3. Radiation Therapy
Radiation therapy uses high-powered beams of energy to target and kill cancer cells. It can be used alone or in combination with chemotherapy.
5.4. Targeted Drug Therapy
Targeted drug therapy focuses on blocking specific weaknesses present within cancer cells. These drugs can be more effective and have fewer side effects than traditional chemotherapy.
