Delving into GI Cancer
Gastro Intestinal Oncology
Unveiling Digestive System Malignancies
Gastrointestinal Cancer
Gastrointestinal cancer, often referred to as GI cancer, is a group of cancers that affect the digestive system.
This includes cancers in the esophagus, stomach, liver, pancreas, gallbladder, small intestine, colon, and rectum. GI cancer can be challenging to detect in its early stages, making understanding its risk factors and symptoms crucial.

Exploring Different Digestive System Tumors
Types of Gastrointestinal Cancer
presents unique challenges and requires tailored treatment approaches.
Esophageal Cancer
Esophageal cancer occurs in the esophagus, the tube connecting the throat to the stomach.
Stomach Cancer
Stomach cancer, also known as gastric cancer, primarily affects the lining of the stomach.
Liver Cancer
Liver cancer, often associated with cirrhosis, hepatitis B and C infections, can develop silently over many years.
Pancreatic Cancer
Pancreatic cancer affects the pancreas, a vital organ that produces digestive enzymes and insulin.
Gallbladder Cancer
This is a formidable disease that affects the gallbladder, a small organ responsible for storing bile produced by the liver.
Colorectal Cancer
Colorectal cancer includes cancers of the colon and rectum. It’s one of the most common GI cancers.
Factors Behind Digestive System Cancer
Causes and Risk Factors
Understanding the causes and risk factors of GI cancer is crucial for prevention and early detection.
Age
More common in older individuals (50-70 yrs), but currently its incidence increases in the younger population too.
Diet & Infections
A diet high in processed foods and low in fiber may contribute to this. Infections like H. pylori and hepatitis B and C can increase risk.
Family History
Individuals with close relatives, such as parents, siblings, or children, who have been diagnosed with GI cancer may have a higher risk.
Tobacco & Alcohol
The combination of both can have a synergistic effect, further increasing the risk. Heavy alcohol consumption can exacerbate the GI system.
Spotting Digestive System Cancer Symptoms
Recognizing Symptoms
The common symptoms of GI cancer can vary depending on the specific type and stage of cancer.
However, there are some general symptoms that may be indicative of GI cancer
Weight Loss
Significant and unexplained weight loss, especially when accompanied by a loss of appetite, can be a red flag for GI cancers.
Digestive Issues
Persistent and unexplained abdominal pain or discomfort can be a symptom, especially if it worsens over time.
Jaundice
Yellowing of the skin and eyes (jaundice) may be a symptom of liver or pancreatic cancer due to the obstruction of bile ducts.
Difficulty Swallowing
Difficulty swallowing food or a feeling of food getting stuck in the throat or chest may indicate esophageal cancer.
Blood in Stool
Rectal bleeding, blood in the stool, or dark, tarry stools can be signs of colorectal cancer or other GI issues.
Nausea and Vomiting
Yellowing of the skin and eyes (jaundice) may be a symptom of liver or pancreatic cancer due to the obstruction of bile ducts.
Diagnosing Digestive System Cancer
Diagnosis
To diagnose gastrointestinal cancer, various procedures are employed.
Colonoscopy
A colonoscopy allows for the examination of the colon and rectum, helping to detect polyps or tumors.
Endoscopy
Endoscopy is used to visualize the esophagus, stomach, and upper part of the small intestine. It aids in diagnosing esophageal and gastric cancers.
Imaging Tests
CT scans, MRIs, and PET scans provide detailed images of the digestive tract, assisting in the detection and staging of cancer.
Approaches for Digestive System Cancer Care
Treatment Options
Surgery is the Main treatment modality. Chemotherapy and Radiotherapy
is used along with Surgery for higher stages and high risk patients.
01.
Surgery
Surgical intervention is often necessary to remove tumors and affected tissue. It can be curative or used in combination with other treatments.
02.
Chemotherapy
Chemotherapy involves the use of drugs to kill gastrointestinal cancer cells. It is commonly used in the treatment of advanced cases.
03.
Radiation Therapy
Radiation therapy employs high-energy rays to target and destroy cancer cells. It is often used in conjunction with surgery or chemotherapy.
