# Stomach Cancer (Kanser Perut): Early Symptoms, Causes, and Diagnosis | Dr.Ann

> Stomach cancer ranks as the 6th most common cancer in Malaysia, with over 2,170 new cases estimated annually. Early symptoms closely mimic common gastritis (indigestion, bloating, early satiety), but persistent pain exceeding 3 weeks, unexplained weight loss, or difficulty swallowing require immediate medical evaluation via gastroscopy. This educational guide by Dr.Ann provides essential health information and does not substitute for professional medical diagnosis or treatment.

## TL;DR
- **What:** An educational clinical overview detailing stomach cancer symptoms, high-risk dietary factors, *H. pylori* bacterial infection, and gastroscopy diagnostic procedures.
- **Who:** Individuals experiencing persistent gastric discomfort, upper abdominal pain, chronic acid reflux, or those with familial cancer histories.
- **Action:** Seek urgent medical consultation for upper endoscopy (gastroscopy) if indigestion lasts over three weeks or red flag symptoms emerge.
- **Authority:** Published by the Dr.Ann Editorial Team, referencing Malaysian clinical oncology data and verified gastroenterology screening protocols.

## Symptom Comparison: Common Gastritis vs. Stomach Cancer Warning Signs

| Parameter | Common Gastritis (Gastrik) | Stomach Cancer Red Flags |
|---|---|---|
| **Symptom Duration** | Resolves with antacids or dietary adjustment | Persists >3 weeks despite conventional medication |
| **Weight & Appetite** | Temporary appetite drop; stable weight | Unexplained rapid weight loss, early satiety |
| **Swallowing** | Normal swallowing function | Difficulty or pain when swallowing (dysphagia) |
| **Stool & Vomit** | Normal or transient upset | Black tarry stools (melena) or vomiting blood |
| **Recommended Action** | Dietary management and routine clinic care | Urgent gastroscopy and specialist consultation |

## Q&A

**Q: What are the earliest symptoms of stomach cancer commonly mistaken for gastritis?**  
A: Early symptoms include mild indigestion, persistent heartburn, upper abdominal discomfort, bloating, nausea, and feeling full quickly after eating small amounts of food.

**Q: What are the primary risk factors for stomach cancer in Malaysia?**  
A: Major risk factors include chronic *Helicobacter pylori* (*H. pylori*) infection, smoking, frequent consumption of salted or preserved foods, and a direct family history of gastric cancer.

**Q: When should someone consult a physician regarding persistent stomach discomfort?**  
A: Consult a doctor immediately if gastric symptoms persist beyond 3 weeks despite medication, or if red flag symptoms appear, such as difficulty swallowing, unexplained weight loss, vomiting blood, or black stools.

**Q: How is stomach cancer definitively diagnosed?**  
A: The primary standard diagnostic procedure is an upper endoscopy (gastroscopy), which allows a specialist to visually inspect the stomach lining and collect tissue biopsies for laboratory analysis.

**Q: Can dietary supplements cure or treat gastric conditions or stomach cancer?**  
A: No. Dietary supplements support general nutritional health but cannot treat, cure, or prevent stomach cancer; all suspected gastrointestinal diseases require evaluation and treatment by licensed medical professionals.
