What is stomach cancer??
Stomach Cancer, also known as gastric cancer, develops when abnormal cells grow within the lining of the stomach. The disease often develops gradually over time and may not cause noticeable symptoms in its early stages. Because early symptoms can be vague and similar to other digestive conditions, stomach cancer is sometimes diagnosed after the disease has progressed. Early evaluation of persistent digestive symptoms is important for timely diagnosis and treatment planning.
Symptoms
- Persistent abdominal discomfort or pain
- Indigestion or heartburn
- Nausea or vomiting
- Feeling full quickly after eating
- Loss of appetite
- Unexplained weight loss
- Bloating after meals
- Difficulty swallowing in some cases
- Vomiting blood or black stools in advanced cases
- Fatigue or weakness related to anemia
Causes & Risk Factors
Several factors may increase the risk of developing stomach cancer, including infection with Helicobacter pylori (H. pylori), chronic stomach inflammation, smoking, heavy alcohol use, obesity, diets high in smoked or processed foods, and a family history of gastric cancer. Certain stomach conditions, prior stomach surgery, and inherited genetic syndromes may also increase risk. Although stomach cancer can occur in younger individuals, it is more commonly diagnosed in older adults.
Gastroenterological Diagnosis & Treatment
Diagnosis may involve upper endoscopy with biopsy, imaging studies, laboratory testing, and endoscopic ultrasound to evaluate the extent of disease. Gastroenterologists play an important role in detecting suspicious stomach abnormalities and guiding further evaluation. Treatment depends on the location and stage of the cancer and may include surgery, chemotherapy, radiation therapy, targeted therapies, immunotherapy, or a combination of treatment approaches. Early detection remains one of the most important factors in improving treatment outcomes and long-term prognosis.
