Understanding Gastric Cancer: What You Need To Know - Best Gynae Oncologist in North Delhi

Gastric cancer, also known as stomach cancer, is a type of cancer that develops in the cells lining the stomach. It is one of the leading causes of cancer-related deaths worldwide, although its incidence has been declining in recent years. Understanding the causes, symptoms, and risk factors of gastric cancer is crucial for early detection and effective treatment. In this article, we will delve into the essentials of gastric cancer, from its underlying causes to its diagnosis and treatment options.

I. Causes and Risk Factors

Gastric cancer typically develops over many years, often starting with changes in the lining of the stomach. While the exact cause of gastric cancer is not fully understood, several factors may increase the risk of developing the disease:

  • Helicobacter pylori infection: Chronic infection with H. pylori bacteria is a major risk factor for gastric cancer, as it can lead to inflammation and damage to the stomach lining over time.
  • Family history: Individuals with a family history of gastric cancer or certain inherited genetic conditions, such as hereditary diffuse gastric cancer (HDGC), are at higher risk.
  • Diet and lifestyle: Poor dietary habits, such as consuming a diet high in salty, smoked, or pickled foods, as well as tobacco use and excessive alcohol consumption, can increase the risk of gastric cancer.
  • Age and gender: Gastric cancer is more common in older adults, with the risk increasing with age. Men are also at slightly higher risk than women.

II. Symptoms and Diagnosis

In its early stages, gastric cancer frequently exhibits no symptoms, making diagnosis difficult. But as the disease progresses, individuals may experience symptoms such as:

  • Persistent abdominal pain or discomfort
  • Unexplained weight loss
  • Loss of appetite
  • Difficulty swallowing
  • Nausea and vomiting
  • Blood in the stool or vomit

Diagnosing gastric cancer typically involves a combination of imaging tests, such as endoscopy, computed tomography (CT) scans, and biopsy. A gastroenterologist or oncologist may perform these tests to confirm the presence of cancer and determine its stage and extent.

III. Treatment Options

The treatment approach for gastric cancer depends on factors such as the stage of the disease, the individual’s overall health, and their preferences. Treatment options may include:

  • Surgery: Surgical removal of the tumor and surrounding tissues is often the primary treatment for localized gastric cancer.
  • Chemotherapy: Chemotherapy uses powerful drugs to kill cancer cells or slow their growth and may be used before or after surgery to shrink tumors or prevent recurrence.
  • Radiation therapy: Radiation therapy uses high-energy rays to destroy cancer cells and may be used in combination with chemotherapy or surgery.
  • Targeted therapy: Targeted therapies target specific molecules or pathways involved in cancer growth and may be used in combination with other treatments for advanced gastric cancer.
