Gastrointestinal Cancers

Gastrointestinal cancers represent a heterogeneous complex array of disorders and diseases. They are classified as either rare inherited forms or more common sporadic forms. Gastrointestinal cancers include tumors of the colon, rectum, stomach, pancreas, esophagus, anus, gallbladder, liver, and bile duct. Cancers of the colorectum, stomach, and pancreas are the most common gastrointestinal cancers

Gastrointestinal (GI) cancer includes all cancers in your digestive tract organs such as the

colonrectal-cancer

Colorectal and GI Cancer

• GI cancers include: Colorectal cancer of the colon or rectum, located at the digestive tract's lower end.
stomach-cancer

Stomach Cancer

• In stomach cancer (also called gastric cancer), cancer cells usually begin on the inner lining of stomach walls and then penetrate deeper into the stomach walls as the cancer develops. The tumor may grow to involve nearby organs like the liver and pancreas.
pancreas-cancer

Pancreatic cancer

• Pancreatic cancer occurs when changes (mutations) in the pancreas cells lead them to multiply out of control. A mass of tissue can result. Sometimes, this mass is benign (not cancerous). In pancreatic cancer, however, the mass is malignant (cancerous).
esophagus-cancer-

Oesophageal cancer

• Oesophageal cancer is a cancer that starts in the food pipe. The food pipe is also called the oesophagus or gullet. Cancer is when abnormal cells start to divide and grow in an uncontrolled way. The cells can grow into surrounding tissues or organs, and may spread to other areas of the body.
Anal-cancer

Anal cancer

• Anal cancer happens when abnormal cells grow and multiply in your anal canal. Anal dysplasia a condition characterized by irregular changes in your cells is a precursor of (comes before) anal cancer.
gallbladder-cancer

Gallbladder cancer

• Gallbladder cancer is a disease in which malignant (cancer) cells form in the tissues of the gallbladder. Gallbladder cancer is a rare disease in which malignant (cancer) cells are found in the tissues of the gallbladder. The gallbladder is a pear-shaped organ that lies just under the liver in the upper abdomen.
liver-cancer

Liver cancer

• Liver cancer is a type of cancer that starts in the liver. Cancer starts when cells in the body begin to grow out of control. To learn more about how cancers start and spread
Bile duct cancer

Bile duct cancer

• Bile duct cancer arises from the cells that line the bile ducts, the drainage system for bile that is produced by the liver. Bile ducts collect this bile, draining it into the gallbladder and finally into the small intestine where it aids in the digestion process. Bile duct cancer is also called cholangiocarcinoma.

Gastrointestinal Cancers

  • Gastrointestinal (GI) Cancer is a collective term that comprises a group of cancers that affect the gastrointestinal tract and digestive system. These cancers develop through the formation of a lump or ulcer within the stomach and spread diffusely throughout the other parts of the stomach.

    The GI cancer includes cancers of the:
    • ✴ Oesophagus
    • ✴ Liver
    • ✴ Gallbladder
    • ✴ Stomach
    • ✴ Biliary tract
    • ✴ Small intestine
    • ✴ Pancreas
    • ✴ Colon
    • ✴ Anus
    • ✴ Rectum

The signs and symptoms of gastrointestinal cancer may vary according to the type of cancer a person has. It may include:

  • ✴ Abdominal pain and discomfort.
  • ✴ Sudden variation in bowel habits, such as consistency, frequency or shape.
  • ✴ Rectal bleeding or blood in the stool
  • ✴ Unusual weight loss
  • ✴ Bloating
  • ✴ Nausea/vomiting
  • ✴ Fatigue
  • ✴ Indigestion
  • ✴ Loss of appetite
  • ✴ Swelling in your stomach
  • ✴ Heartburn
  • ✴ Constipation or diarrhea
  • ✴ Weakness or feeling tired
  • ✴ Yellowish eyes or skin

To diagnose and identify the spread of cancer your GI oncology doctor may conduct several tests including:

  • Endoscopic examinations:

    In this process, a tiny camera attached to a thin tube is passed down to the stomach, through the throat. If any malignant area is found the tissue is sent for analysis (biopsy). This may be conducted using the following endoscopic methods: I. Upper GI Endoscopy

  • Imaging Studies:

    Imaging techniques identify stomach cancers using computerized process and special X-ray examinations including:

    1. CT Scan
    2. MRI Scan
    3. PET Scan
    4. Contrast Studies
  • iagnostic Laparoscopy
  • Barium Studies

GI cancers include: colorectal cancer (CRC), gastric cancer, liver cancers (e.g. hepatocellular carcinoma [HCC]), esophageal cancer and pancreatic cancer.
