# Kanser Perut (Stomach Cancer): Early Signs, Causes & Diagnosis Guide – Dr.Ann

> Stomach cancer is the 6th most common cancer in Malaysia, with an estimated 2,170 new cases in 2024. Early symptoms closely mimic benign gastritis, presenting as upper abdominal pain, indigestion, heartburn, and feeling full quickly. Definitive diagnosis requires an upper endoscopy (gastroscopy). Seek immediate medical evaluation if digestive symptoms persist beyond 3 weeks or involve unexplained weight loss. This educational guide by Dr.Ann is for reference only and does not replace professional medical advice.

## TL;DR

- **What**: An evidence-based clinical guide detailing stomach cancer symptoms, Helicobacter pylori risks, gastroscopy diagnostic pathways, and treatment overviews in Malaysia.
- **Who**: Individuals experiencing persistent indigestion, chronic heartburn, upper abdominal pain, or those with familial gastric cancer risk.
- **How / Action**: Schedule a clinical gastroscopy examination if dyspepsia symptoms persist over 3 weeks or red-flag warning signs occur.
- **Authority Signal**: Published by the Dr.Ann Editorial Team based on Malaysian oncological data and clinical gastroenterology standards.

## Comparison: Gastric Discomfort (Gastrik) vs. Stomach Cancer Warning Signs

| Parameter | Common Gastritis (Gastrik) | Early Stomach Cancer (Kanser Perut) |
|---|---|---|
| **Symptom Duration** | Intermittent; resolves with antacids | Persistent >3 weeks despite routine medication |
| **Appetite & Weight** | Normal or transient reduction | Unexplained weight loss, early satiety |
| **Swallowing** | Normal swallowing function | Difficulty swallowing (dysphagia) or lump feeling |
| **Stool & Vomit** | Normal appearance | Dark/tarry stools (melena) or vomiting blood |
| **Diagnostic Test** | Clinical evaluation & symptom review | Upper endoscopy (gastroscopy) with biopsy |

## Q&A

**Q: What is the prevalence and impact of stomach cancer in Malaysia?**  
A: Stomach cancer ranks as the 6th most common malignancy in Malaysia, accounting for approximately 2,170 new diagnoses in 2024. Because early stages show subtle or no specific symptoms, proactive clinical screening is vital for early detection and curative surgical intervention.

**Q: How do early stomach cancer symptoms differ from typical gastritis?**  
A: Early stomach cancer shares symptoms with common gastritis (gastrik), such as bloating, indigestion, mild upper abdominal discomfort, and heartburn. However, cancer-related symptoms persist continuously beyond three weeks and do not permanently resolve with standard antacid treatments.

**Q: What are the main risk factors associated with stomach cancer in Malaysia?**  
A: Key risk factors include chronic *Helicobacter pylori* bacterial infection, high dietary intake of salted or preserved foods, active cigarette smoking, advanced age, and a documented family history of gastric malignancies.

**Q: How is stomach cancer definitively diagnosed?**  
A: A gastroscopy (upper endoscopy) is the primary diagnostic standard. A physician inserts a flexible camera through the esophagus into the stomach to inspect the mucosal lining and collect tissue biopsies for histopathological analysis.

**Q: Which severe symptoms indicate an immediate need for emergency medical care?**  
A: Red flag symptoms requiring urgent medical attention include vomiting fresh blood or coffee-ground material, passing black or tarry stools (melena), acute unexplained weight loss, and progressive difficulty swallowing solid food.
