13 common signs of stomach cancer
Stomach cancer refers to abnormal cell growth in the organ. Also known as gastric cancer, the condition progresses slowly and may eventually spread to the liver and pancreas. About 95% of stomach cancers develop in the cells of the stomach lining, whereas rarer types may originate in the lymph nodes or the connective tissue of the stomach wall. Recognizing the early signs of stomach cancer can help get a timely diagnosis and treatment.
Signs
The progression of stomach cancer is gradual, and those with this condition may or may not experience any early signs. The symptoms usually begin to appear only after the cancer begins spreading to other organs. The following are possible indicators that one has stomach cancer:
Abdominal pain
Severe abdominal pain is an early sign of stomach cancer. The pain may spread to the back in cases where the cancer is developing in the stomach’s lymph nodes.
Stomach swelling
If cancer spreads to the tissue lining the abdomen, one may observe swelling in the stomach. This swelling is caused by the accumulation of a fluid known as ascites.
Diarrhea or constipation
The spread of cancer cells to the small intestine can cause blockages, leading to diarrhea. In contrast, tumors in the abdomen may narrow the bowel, triggering constipation.
Blood in the stool
Although blood in the stools is a rare symptom of stomach cancer, it may sometimes be a sign of bleeding from the tumor. So, a doctor should be consulted immediately in case one observes blood in their stools.
Nausea and vomiting
The stomach is an integral part of the gastrointestinal tract. So, when the cancerous cells developing in the stomach spread to other organs, it may cause blockages, which can trigger nausea and vomiting.
Anemia
The bleeding associated with stomach cancer often leads to a reduction of red blood cell count or anemia.
