What is the symptom of stomach cancer?

Common symptoms of stomach cancer may include:

- Persistent indigestion and heartburn. This is often one of the first symptoms of stomach cancer. It may be mild at first, but it can become more severe and frequent over time.

- Abdominal pain. This can be a dull, aching pain in the upper abdomen, or it can be a sharp, stabbing pain. It may be worse after eating, or it may come and go throughout the day.

- Nausea and vomiting. This is another common symptom of stomach cancer. It may be accompanied by a feeling of fullness or bloating, or it may occur for no apparent reason.

- Diarrhea or constipation. These are also common symptoms of stomach cancer. They may be caused by the tumor blocking the passage of food and waste through the digestive tract.

- Loss of appetite and weight loss. This is often a late symptom of stomach cancer, but it can occur earlier in some cases. It is caused by the tumor using up the body's energy stores and making it difficult to digest food.

- Other symptoms. Stomach cancer can also cause a number of other symptoms, such as fatigue, weakness, anemia, and dark stools.

It is important to note that these symptoms can also be caused by other conditions, such as gastritis, ulcers, and irritable bowel syndrome (IBS). If you are experiencing any of these symptoms, it is important to see your doctor for a diagnosis.
