Stomach Cancer

Stomach cancer, also known as gastric cancer, is a type of cancer that starts in the cells lining the stomach. It is a relatively uncommon cancer, but it can be aggressive and challenging to treat, especially when diagnosed at an advanced stage.

Causes and Risk Factors:

The exact cause of stomach cancer is not well understood, but certain risk factors may increase the likelihood of its development.

• Helicobacter pylori Infection: Chronic infection with the bacterium Helicobacter pylori is a major risk factor for stomach cancer.
• Age: The risk of stomach cancer increases with age, with most cases diagnosed in individuals over 65.
• Gender: Stomach cancer is more common in men than in women.
• Family History: A family history of stomach cancer can increase the risk.
• Diet: Consuming a diet high in salty and smoked foods, pickled vegetables, and low in fruits and vegetables may be a risk factor.
• Tobacco and Alcohol Use: Smoking and heavy alcohol consumption are associated with an increased risk.
• Previous Stomach Surgery: Individuals who have undergone certain types of stomach surgery may be at a higher risk.
• Pernicious Anemia: A condition in which the stomach lacks a protein that aids in the absorption of vitamin B12.

Symptoms:

In the early stages, stomach cancer may not cause noticeable symptoms. As the disease progresses, common symptoms may include:

• Indigestion and Heartburn: Persistent discomfort or pain in the upper abdomen.
• Loss of Appetite: A feeling of fullness after eating small amounts of food.
• Unexplained Weight Loss: A sudden and unexplained drop in weight.
• Nausea and Vomiting: Especially after eating.
• Difficulty Swallowing: Dysphagia or a feeling of food getting stuck in the throat.
