Symptoms Of Stomach Cancer
Stomach cancer, commonly referred to as gastric cancer, is a cellular formation found in the stomach which spreads rapidly throughout, affecting other organs, particularly the esophagus, lungs, lymph nodes and the liver. Adenocarcinoma is the most common form of cancer found among patients suffering with cancer of the stomach worldwide.
The stomach is a muscular sac with a storage capacity of about a liter or a quart, serving as a reservoir and the site of breakdown for ingested food. It is located along the gastrointestinal tract between the esophagus and the small intestine. The inner lining of the stomach is known to produce certain digestive acids and enzymes and it is this lining which serves as the breeding ground to a cancer.
These cancer cells further spread by navigating away from the mother tumor and entering the blood vessels or the lymph vessels, which branch into all the tissues of the body. These cells then attach themselves to the destination tissues and grow into new tumors. This cycle of spread of cancer cells is called metastasis.
Some other causes of stomach cancer include an infection caused by Helicobacter pylori bacterium. Autoimmune atrophic gastritis, intestinal metaplasia and various other genetic factors are also related with the increased risk of the cancer of the stomach.
Stomach cancer, often, has merely vague or no symptoms in the earlier stages of growth. Symptoms may also vary among patients depending upon the stage and the type of growth of tumor cells.
However, some of the most common symptoms of stomach cancer experienced by patients worldwide are:
Blood in the Stool: While blood in the stools maybe due to lesser serious conditions like hemorrhoids and anal fissures, it also indicates towards a possible stomach cancer.
Abdominal Pain, Discomfort and Irritation: One of the most common symptoms of stomach cancer, abdominal pain (generally in the upper abdominal area) can range from a mild discomfort to an excruciating pain.
Persistent Nausea and/or Vomiting: Persistent nausea or vomiting is an indication towards a possible cancerous growth as stomach cancer often causes damage to the inner lining of the esophagus.
Loss of Appetite: A longer loss of appetite is often treated as a vague symptom for stomach cancer.
Abdominal Bloating: Again, abdominal bloating is one of the most prevalent symptoms of stomach cancer, mostly experience after ingestion. Indigestion and heartburn also accompany abdominal bloating in a lot of cases.
Constipation and/or Diarrhea: Constipation and Diarrhea spread over longer periods are also potential symptoms of a cancerous formation in the stomach.
Weakness and Fatigue: Fatigue lasting more than a few days is often related to a possible stomach cancer.
Loss of Weight: A loss of more than 5 percent of the normal body weight in the course of six months or less is one of the most common symptoms of a cancerous development in the stomach.
