Understanding Gastric Cancer: Signs and Risks

Gastric cancer, also known as stomach cancer, involves abnormal cell growth in the stomach's lining. Often silent in early stages, its symptoms may be subtle or absent, making early detection challenging. When symptoms do appear, they can include discomfort and pain. This article explores common signs and potential causes of gastric cancer.

Recognizing Symptoms of Stomach Cancer

Persistent Heartburn
While occasional acid reflux is common, frequent heartburn may indicate gastric issues in some cases.

Difficulty Swallowing
Challenges in swallowing can result from tumors obstructing the esophagus or as a side effect of treatments.

Decreased Appetite and Early Satiety
The presence of a tumor can irritate the stomach lining, leading to swelling, altered digestion, and reduced appetite. Small meals may cause quick feelings of fullness, affecting nutritional intake.

Weight Loss Suddenness
Persistent fullness and bloating can reduce food consumption, resulting in unintended weight loss. Medications and treatments may also contribute to appetite loss.

Jaundice
Although uncommon, jaundice may develop if cancer spreads to the liver or bile ducts, or if tumors block bile flow.

Blood in Stool
Stomach inflammation or bleeding can cause blood to appear in stools.

Abdominal Pain and Cramps
Cramping and pain, often worsening after eating, are typical symptoms that vary in intensity.

Nausea and Vomiting
Patients may vomit solids or feel nauseous, sometimes with blood, which can hinder eating and hydration.

Causes of Gastric Cancer

The precise cause remains uncertain, but it involves abnormal cell growth in the stomach lining. Rapid multiplication of these cells forms tumors, which can invade nearby tissues, lymph nodes, and organs over time.
