There is no clear data about the low percentage of weight loss in early stage of stomach cancer, which is related to the patient’s physique.
Gastric cancer is a malignant tumor originated from epithelial cells of the stomach, and in the early stage, it usually does not have obvious uncomfortable symptoms and seldom has body wasting, only a very small number of patients will have weight loss, but there is no way to determine the specific proportion.
Most of the stomach cancers start to show regurgitation, vomiting, blood in stool and body wasting only after entering into middle and late stages, because cancer itself is a consumptive disease, and stomach cancer affects the nutrient absorption of food, so the longer the disease lasts, the more obvious the body wasting will be.
