Stomach cancer, also known as gastric cancer, is a condition where malignant cells form in the lining of the stomach. It is the fifth most common cancer worldwide and the third leading cause of cancer-related deaths. Understanding the risks, recognizing the symptoms early, and knowing the treatment options can significantly improve the prognosis and quality of life for those affected by this disease. This comprehensive guide will explore the risks, early detection methods, and treatment options for stomach cancer.
Understanding Stomach Cancer
Stomach cancer typically begins in the cells that line the stomach. The most common type is adenocarcinoma, which starts in the glandular cells of the stomach lining. Other less common types include lymphomas, gastrointestinal stromal tumors (GISTs), and carcinoid tumors.
Types of Stomach Cancer
- Adenocarcinoma: The most prevalent type, accounting for about 90-95% of all stomach cancers. It starts in the glandular cells of the stomach lining.
- Lymphomas: Cancers of the immune system tissue found in the stomach wall.
- Gastrointestinal Stromal Tumors (GISTs): Rare tumors that originate from a specific type of cell in the stomach wall called the interstitial cells of Cajal.
- Carcinoid Tumors: Develop from hormone-producing cells in the stomach.
