Stomach Cancer

Stomach cancer begins when cells in the stomach start to grow uncontrollably. Over time, these cells can form a tumor, leading to cancer. The earlier it's detected, the better the prognosis. But what are the early signs to watch out for?

Symptoms of Stomach Cancer

1. Unexplained Weight Loss

A sudden and significant drop in weight without any apparent reason, such as changes in diet or exercise habits, can be a primary indicator. This weight loss can be due to the cancer affecting the stomach's ability to digest food or the body's increased energy expenditure to fight the disease.

2. Persistent Indigestion and Heartburn

Regular discomfort, especially after meals, that doesn't alleviate with over-the-counter antacids. This symptom arises because the tumor can interfere with the stomach's normal function, leading to acid reflux and irritation.

3. Stomach Pain or Discomfort

A continuous or intermittent pain localized in the upper abdomen. The pain can range from a dull ache to a sharp sting, often worsening after meals. This discomfort is due to the tumor's growth, which can press against neighboring organs or tissues.

4. Feeling Full After Eating Small Amounts

A sensation of fullness after consuming only a small portion of food, known as early satiety. This occurs because the tumor can reduce the stomach's capacity or affect its ability to expand when food enters.

5. Difficulty Swallowing

Challenges in swallowing, especially solid foods, can indicate a tumor's presence in the upper part of the stomach or the esophagus. This symptom, known as dysphagia, results from the narrowing of the passage due to the tumor's growth.

6. Nausea and Vomiting

Persistent nausea or episodes of vomiting, especially if blood is present. This can be due to the tumor obstructing the passage of food or the stomach's reduced ability to empty its contents.

7. Anemia and Fatigue

Symptoms like constant tiredness, shortness of breath, or pale skin can be indicative of anemia. This condition arises when the tumor causes internal bleeding, leading to a reduction in red blood cells.

8. Changes in Bowel Habits

The presence of blood in the stool, black or tarry stools, or persistent constipation or diarrhea. These changes can result from the tumor affecting the digestive process or bleeding into the gastrointestinal tract.

9. Swelling or Fluid Build-up in the Stomach

A bloated feeling or visible swelling in the abdominal area can indicate ascites, where fluid accumulates in the abdomen due to the cancer affecting the liver or lymphatic system.

10. Loss of Appetite:

A sudden decrease in the desire to eat or an aversion to specific foods. This can be due to the tumor affecting the stomach's normal function or releasing substances that reduce appetite.

It's essential to understand that while these symptoms can indicate stomach cancer, they can also be associated with other, less severe conditions. However, if these symptoms persist or are combined, it's crucial to seek medical advice. Early detection is key to improving the prognosis and treatment outcomes for stomach cancer.


Several factors can increase the risk of stomach cancer, including a diet high in salty and smoked foods, a history of stomach polyps or stomach inflammation, certain genetic mutations, smoking, and infections with the bacterium Helicobacter pylori.
Diagnosis typically involves a combination of physical exams, blood tests, endoscopy (where a camera is used to inspect the inside of the stomach), and imaging tests like CT scans. If a suspicious area is found, a biopsy might be taken to check for cancer cells.
While no method guarantees prevention, certain lifestyle changes can reduce the risk. This includes eating a diet rich in fruits and vegetables, reducing salt and smoked foods, quitting smoking, and treating Helicobacter pylori infections promptly.
Treatment options depend on the cancer's stage and location, as well as the patient's overall health. Common treatments include surgery to remove the tumor, chemotherapy, radiation therapy, targeted drug therapy, and immunotherapy.
If detected early, stomach cancer is more treatable, and the chances of a cure are higher. However, many cases are diagnosed at a more advanced stage, making treatment more challenging. Regular check-ups and being aware of the symptoms can aid in early detection.
