"How Do Gastric Cancer and Intestinal Cancer Differ from Each Other?"

Although the intestines and stomach are two distinct organs, they frequently encounter issues concurrently when affected by illness. The multitude of causes underpinning gastrointestinal diseases predominantly stems from unhealthy dietary habits. Among the most severe intestinal and gastric ailments, colon cancer and gastric cancer exhibit conspicuous clinical manifestations. Notably, the pain they inflict upon the stomach differs significantly.

1. Differences between Gastric Cancer and Colon Cancer

Gastric cancer, a malignancy originating from the gastric epithelium, ranks as the most prevalent malignancy in China. Dietary nitrites serve as the primary pathogenic factor, abundant in pickled vegetables, which convert to nitrites through the action of nitrate reductase in the stomach, thereby contributing to gastric cancer development. Conversely, colon cancer is fueled by high-fat diets, which elevate bile acid concentrations in the large intestine, fostering its onset. Furthermore, high-fat diets often entail increased meat consumption, and during frying and grilling, carcinogenic substances like cyclic amines may form. Consequently, these two diseases possess inherent differences.

2. Symptoms of Early Gastric Cancer

2.1 Upper Abdominal Discomfort: Primarily manifested as a sensation of fullness or burning, which may temporarily abate but recurs frequently.

2.2 Dark Stool or Positive Fecal Occult Blood: The appearance of black stool without consuming blood tofu or taking bismuth-containing medications necessitates prompt medical attention.

2.3 Symptoms of Anorexia, Belching, and Other Digestive Issues: Characterized by postprandial fullness sensations, actively restricting dietary intake, often accompanied by recurrent belching.

2.4 Upper Abdominal Pain: The most prevalent symptom of gastric cancer, initially presenting as intermittent dull pain, often misdiagnosed as gastritis or ulcer disease.
