A significant amount of gastric or stomach abnormal growths include both benign and cancerous lesions. Several types of malignant cancers begin in the stomach, but the majorities are primary cancers which developed in the mucosal glands.

Among the types of stomach cancers, carcinomas can be grouped according to the total appearance:

1.         Protruding

2.         Penetrating

3.         Spreading

The Stomach

The stomach is a musculo-membranous structure joined by the esophagus and the duodenum or small intestines. The stomach is shaped like the letter J and it serves as a food reservoir and an initiator of the digestive process. The food is held in the stomach temporarily until the stomach lining secretes gastric juices which act on the food to break it down chemically.


In the early stages of this cancer, there may not be any specific symptoms. Early stomach cancer can have very mild symptoms that may appear as simple indigestion. Other symptoms may include:

•          Feeling of being full after eating only a small amount of food

•          Heartburn

•          Unexplained weight loss

•          Vomiting

•          Difficulty swallowing

•          Pain in the abdomen

•          Dark bowel movements or blood in the stool

•          No appetite

•          Difficulty swallowing
