We also provide on-site cancer surgery, post-cancer care, and quick diagnosis thanks to our affiliation with a top gastroenterology team in the globe. In case you’re seeking a diagnosis and therapy for stomach cancer.

Gastric cancer is another name for stomach cancer. This is where cancer cells proliferate uncontrollably in your stomach. Anywhere in your stomach can be the source of cancer. The gastroesophageal junction, which is the point where your stomach and oesophagus meet, is where aberrant cell growth occurs in the majority of stomach cancer cases. Stomach cancer begins in the lining of your stomach approximately 94% of the time and spreads gradually. If left untreated, it may develop into a mass (tumour) that grows deeper into the walls of your stomach. Your pancreas and liver are two adjacent organs where the tumour might spread.

Types of GI Cancer

Cancer can manifest in various types depending on its location within the body:

  1. Adenocarcinoma, the most prevalent form of stomach cancer, develops in the mucosa or the innermost lining of the stomach, constituting 90-95% of cases.
  2. Lymphoma, a rare occurrence in the stomach, represents a cancer of immune system tissues. Treatment approaches are contingent on the specific type of lymphoma involved.
  3. Gastrointestinal stromal tumor (GIST) is an uncommon tumor originating in specialized cells known as interstitial cells of Cajal (ICC). While it can emerge in any part of the digestive tract, it is more frequently observed in the stomach.
  4. Carcinoid tumor arises in stomach cells responsible for hormone production. Although rare, it typically does not metastasize to other organs.

Causes for Stomach Cancer

Each type of gastrointestinal (GI) cancer is associated with specific risk factors, yet lifestyle elements often play a contributory role. Factors such as obesity, sedentary lifestyle, smoking, poor dietary habits, and excessive alcohol consumption are noteworthy examples. Additionally, a familial predisposition can increase susceptibility to the disease. Other considerations include:

  1. Hepatitis A or B Infection: Persistent infections of Hepatitis A or B may culminate in the development of liver cancer.
  2. Helicobacter pylori Infection: Unaddressed, chronic H. pylori infections can contribute to the onset of stomach cancer.
  3. Smoking and Alcohol Consumption: Engaging in cigarette smoking and consuming alcohol elevates the risk of developing GI cancers.
  4. Gastritis: A prolonged history of gastritis is linked to an increased likelihood of gastrointestinal cancers.
  5. Obesity: Individuals with obesity face a heightened risk of GI cancers.
  6. History of Any GI Cancers or Other Cancers: Those with a medical history of GI or other cancers are at an increased risk of developing gastrointestinal cancers.
  7. History of Polyp Growths in the Colon or Stomach: Individuals with a history of polyp growths in the colon or stomach region exhibit a higher risk for GI cancers.

Diagnosis at Dr. Subash K G

  1. Physical Examination: A thorough physical examination is conducted to identify any abnormalities, such as lumps or other signs indicative of disease. The patient’s health habits, previous illnesses, and treatments are also considered in the medical history.
  2. Blood Tests: Screening for abnormalities in the blood that may signal the presence of GI malignancies is accomplished through blood tests.
  3. Endoscopy: Endoscopic examinations involve using a flexible tube equipped with a light and a small camera (endoscope) to visually inspect the interior of the body.
  4. Imaging Tests: Different imaging studies, including MRI, X-ray, ultrasound, CT scan, or PET scan, are employed to detect abnormal tissue anywhere in the digestive system.
  5. Colonoscopy and Sigmoidoscopy: These procedures are utilized for the identification of colorectal cancer.
  6. Upper GI Endoscopy: This procedure facilitates the detection of cancers originating from the lining of the esophagus, stomach, and duodenum in the upper gastrointestinal system.
  7. Biopsy: The biopsy process entails collecting cells or tissues from the suspected tumor growth area. These samples are then examined under a microscope for signs of cancer, with routine stomach biopsies often conducted during endoscopy.
