The first stage of stomach cancer (stomach cancer) rarely shows any symptoms. Stomach cancer is not routinely screened for, for example, in the United States, most cases of stomach cancer are not detected until they are large enough or have spread outside the stomach.
Stomach cancer causes signs and symptoms that may include:
Weight loss (effortless)
Abdominal (animal) pain
Vague discomfort in the abdomen, usually above the navel
After eating a little, you feel full
Heartburn or upset stomach
Vomiting with or without blood
Swelling or accumulation of fluid in the abdomen
Blood in the stool
Fatigue and weakness due to anemia (anemia).
Yellowing of the skin and eyes (jaundice) if the tumor has spread to the liver.
Many of these symptoms are not caused by stomach cancer, but by other causes such as viral infections or ulcers. Some of these symptoms can be caused by other types of cancer. But people with any of these problems, especially if they persist or worsen, should see a doctor to find out the cause and treat it if necessary.
