Introduction
Gastric cancer, commonly known as stomach cancer, is a serious condition that develops when malignant cells grow uncontrollably in the lining of the stomach. It is one of the leading causes of cancer-related deaths worldwide, mainly because it is often diagnosed at an advanced stage. The early signs of gastric cancer can be subtle and easily mistaken for common digestive issues, making awareness of its key indices (risk factors) and manifestations (symptoms) crucial for early detection and treatment.
This essay explores six critical indices (risk factors) and manifestations (symptoms) of gastric cancer that should not be ignored.
Indices (Risk Factors) of Gastric Cancer
Certain lifestyle habits, infections, and genetic factors increase the likelihood of developing gastric cancer. Here are three major indices:
1. Helicobacter pylori (H. pylori) Infection
One of the strongest risk factors for gastric cancer is chronic infection with H. pylori, a bacterium that infects the stomach lining.
🔹 How It Increases Risk:
- Causes chronic inflammation in the stomach (gastritis), leading to cellular damage.
- Can result in stomach ulcers, which may progress to cancer over time.
🔹 Warning Signs:
- Persistent indigestion
- Burning stomach pain
- Frequent bloating
Prevention Tip: Early diagnosis and treatment of H. pylori with antibiotics can lower cancer risk.
2. High-Salt and Processed Food Diet
A diet rich in salty, smoked, and processed foods increases the risk of gastric cancer.
🔹 Why It’s Dangerous:
- Salt damages the stomach lining, making it more vulnerable to cancer-causing agents.
- Smoked meats and pickled foods contain nitrates and nitrites, which can transform into carcinogenic compounds.
🔹 Common Foods to Watch Out For:
- Pickled vegetables
- Processed meats (bacon, sausages, ham)
- High-salt instant noodles and snacks
Prevention Tip: Eating a balanced diet with fresh fruits, vegetables, and fiber can reduce stomach cancer risk.
