9 Causes of Gastric Cancer, Symptoms and Prevention

9 Causes of Gastric Cancer, Symptoms and Prevention/Stomach cancer, also known as gastric cancer, is a type of cancer that begins in the cells lining the stomach. The stomach is a J-shaped organ located in the upper abdomen, and its main function is to help digest food. Stomach cancer is a result of the uncontrolled growth of abnormal cells within the lining of the stomach.

the cause of stomach cancer

Helicobacter pylori (H. pylori) infection: Chronic infection with H. pylori is a major risk factor for stomach cancer. This bacterium can cause inflammation of the stomach lining, which, if left untreated, may lead to the development of cancerous cells. H. pylori infection is common worldwide and can be diagnosed through various tests, including blood tests and endoscopy.

Age: Stomach cancer is more prevalent in older individuals, with the risk increasing as age advances. While it can affect people of any age, the majority of cases occur in individuals over 65 years old.

Gender: Men are generally more prone to stomach cancer than women. The reasons for this gender difference are not entirely understood but may be influenced by hormonal and lifestyle factors.

Tobacco use: Smoking has long been recognized as a significant risk factor for stomach cancer. The harmful chemicals in tobacco smoke can damage the stomach lining, promoting the development of cancerous cells. Quitting smoking can substantially reduce this risk.

Diet: Certain dietary patterns have been linked to an increased risk of stomach cancer. Consuming a diet high in salt, smoked or pickled foods, and low in fruits and vegetables may elevate the risk. Conversely, a diet rich in antioxidants from fruits and vegetables may have a protective effect.

Family history: Individuals with a family history of stomach cancer, especially in first-degree relatives, have a higher risk. Genetic factors may play a role in predisposing certain families to this type of cancer.

Certain medical conditions: Chronic gastritis, pernicious anemia, and stomach polyps are conditions associated with an elevated risk of stomach cancer. These conditions can cause long-term inflammation or changes in the stomach lining, increasing susceptibility to cancer development.

Previous stomach surgery: Some types of stomach surgeries, such as partial gastrectomy, may increase the risk of stomach cancer. The alteration in the anatomy of the stomach can affect its normal functions and potentially contribute to cancer development.

Occupational exposure: Certain occupational exposures, such as working in industries involving dust and fumes, may be associated with an increased risk of stomach cancer. Occupational safety measures are crucial in minimizing these risks.

gastric cancer symptoms

Abdominal Pain: Persistent or recurrent pain in the upper abdomen may be a symptom of stomach cancer. This pain can be dull, constant, or sharp.

Unexplained Weight Loss: Significant and unintentional weight loss, especially without changes in diet or physical activity, may be indicative of stomach cancer.

Nausea and Vomiting: Continuous nausea and vomiting, particularly if it contains blood, can be a sign of stomach cancer. The tumor’s growth may obstruct the normal passage of food.

Difficulty Swallowing (Dysphagia): Trouble swallowing or a sensation of food getting stuck in the throat or chest could be a symptom, especially as the tumor affects the ability to swallow.

Blood in Stool: Stomach cancer can cause bleeding in the digestive tract, leading to the presence of blood in the stool. This may manifest as black, tarry stools (melena) or visible blood.

Fatigue: Persistent fatigue and weakness may be associated with stomach cancer, especially if the body is not receiving adequate nutrients due to the tumor’s impact on digestion.

Early Satiety: Feeling full or bloated after consuming small amounts of food can be a symptom of stomach cancer, as the tumor affects the stomach’s capacity.

Heartburn or Indigestion: Chronic or severe heartburn, indigestion, or acid reflux that does not respond well to typical treatments may be a cause for concern.

Ascites: As stomach cancer progresses, it can lead to the accumulation of fluid in the abdominal cavity, causing swelling and discomfort. This condition is known as ascites.

Healthy Diet: Adopting a balanced and nutritious diet is crucial. Include plenty of fruits and vegetables, and try to limit the intake of salty, smoked, or pickled foods. A diet rich in antioxidants can help protect cells from damage.

Limiting Processed Foods: Reducing the consumption of processed meats and foods with added preservatives may contribute to a lower risk of stomach cancer.

Avoiding Tobacco Products: Smoking is a significant risk factor for stomach cancer. Quitting smoking or avoiding tobacco products altogether can greatly reduce the risk.

Moderate Alcohol Consumption: Excessive alcohol consumption has been linked to an increased risk of stomach cancer. Moderation in alcohol intake is recommended for overall health.

Treating H. pylori Infections: Infections with Helicobacter pylori (H. pylori) bacteria have been associated with an increased risk of stomach cancer. Treating and eradicating H. pylori infections can be a preventive measure.

Regular Exercise: Engaging in regular physical activity not only contributes to overall health but has also been linked to a reduced risk of various cancers, including stomach cancer.

Maintaining a Healthy Weight: Obesity has been associated with an increased risk of several cancers, including stomach cancer. Maintaining a healthy weight through a balanced diet and regular exercise can be beneficial.

Screening and Early Detection: For individuals with a family history of stomach cancer or other risk factors, regular screenings and endoscopic examinations may aid in the early detection of precancerous lesions.

Occupational Safety: Some occupations involving exposure to dust, fumes, or certain chemicals may increase the risk of stomach cancer. Adhering to safety guidelines in the workplace can help minimize such risks.

Addressing Stomach Conditions: Treating and managing conditions such as chronic gastritis, stomach polyps, or other gastrointestinal disorders may help reduce the risk of stomach cancer.
