From a pathological perspective, cancers occur due to the failure of the immune system. It is evident that the immune system plays key roles in preventing cancer through regulating cell population in the body. Ordinarily, the body’s immune system is usually involved in some cellular processes, especially in the cell cycle in which it destroys old or defective cells through programmed cell death, a process commonly known as apoptosis. In the context of cancer, this process is usually impaired, thus damaged or defective cells are not destroyed by the immune system. In addition, the impairment of the immune system’s activity affects cellular homeostasis processes including irregular cell division. These factors are responsible for tumor growth and progression of cancer. Gastric cancer affects the digestive system, primarily the stomach. Anatomically, the stomach occupies the region from the esophageal junction to the duodenum. Therefore, aim of this research is to carry out a comprehensive review of gastric cancer, also known as stomach cancer.

Zusammenfassung der Kapitel (Chapter Summaries)
- Introduction: This chapter introduces the concept of cancer from a pathological perspective, emphasizing the role of the immune system in preventing and regulating cell populations. It highlights the impairment of immune function in cancer development, particularly in gastric cancer, which affects the digestive system.
- Biological Changes during Onset and Progression of Gastric Cancer: This chapter examines the genetic and epigenetic modifications that occur in gastric cells during the onset and progression of cancer. It explores the impact of these alterations on gene expression, protein production, and cellular processes.
- Distinctive Characteristics of Cancer Cells: This chapter contrasts the characteristics of cancer cells with normal cells, focusing on differences in shape, size, nucleus appearance, and tissue arrangement. It emphasizes the significance of these distinctions in pathological investigations.
- Effect of Gastric Cancer in the Body: This chapter delves into the pathophysiology of gastric cancer, explaining how the disease affects the body as it progresses. It examines the disruption of stomach function, potential bleeding, and the phenomenon of metastasis.
