Dr. Sharat Chandra, an experienced oncologist in Hyderabad’s Banjara Hills, has a good reputation for his patient-centered approach to identifying and treating tumors, particularly gastrointestinal (GI) malignancies.

He specializes in sophisticated treatment techniques and complete oncology services, treating tumors such as breast, lung, blood, and gastrointestinal cancer. Early identification and treatment are critical to increasing survival rates and quality of life.

Dr. Chandra specializes in tailored care plans for breast, lung, gastrointestinal, and blood cancers, giving a holistic approach to cancer diagnosis and treatment.

“Early detection saves lives. Regular screenings and awareness of symptoms are key to beating GI cancers.” – Dr. Sharat Chandra

Understanding Gastrointestinal (GI) Cancer

GI cancer is the unrestrained growth of abnormal cells in the digestive tract. These malignant cells can create tumors that can grow locally or spread (metastasize) throughout the body.

What is the most common gastrointestinal (GI) cancer?

Colorectal cancer is the most often diagnosed gastrointestinal cancer worldwide, particularly in developed nations. In the United States, colorectal cancer is the third most frequent cancer in both men and women, excluding skin cancers.

Stomach cancer is common worldwide, particularly in East Asia, while liver and pancreatic tumors are on the rise.

Why is Gastrointestinal Cancer (GI) a Global Risk?

  • High Incidence: Millions of people are afflicted globally.
  • Low Survival Rates: Because of late discovery, some forms, such as pancreatic cancer, have a dismal prognosis.
  • Lifestyle factors such as poor diet, smoking, alcohol consumption, and obesity all raise the risk.

Common Types of Gastrointestinal Cancers

Here are the five most common types of GI cancers:

Liver CancerLiverJaundice, pain, loss of appetite, fatigueSurgery, Ablation, Radiation
Pancreatic CancerPancreasJaundice, back pain, digestive issuesBlood in stool, bowel habit changes, and anemia

Detailed Explanation of Common GI (Gastrointestinal) Cancers

1. Esophageal Cancer

  • The main symptoms are weight loss, chest pain, persistent coughing, and difficulty swallowing.
  • Risk factors include obesity, GERD, alcohol use, and smoking.
  • Treatment options include radiation, chemotherapy, endoscopic procedures, and surgery.

“Esophageal cancer often progresses silently. Regular check-ups are vital if you have risk factors.” – Dr. Sharat Chandra

2. Stomach (Gastric) Cancer

  • Symptoms include heartburn, exhaustion, nausea, severe stomach discomfort, and inexplicable weight loss.
  • Causes include a poor diet, alcohol use, smoking, obesity, and family history.
  • Treatment: Medication, radiation, chemotherapy, and surgery.

Pro Tip: To reduce risk, eat less processed and salty meals.

3. Colorectal Cancer

  • This kind frequently begins as benign polyps that eventually turn into cancer.
  • Early warning signs include flatulence, diarrhea, blood in the stool, and unexplained anemia.
  • Age, family history, a sedentary lifestyle, and a diet heavy in red meat are important risk factors.
  • Options for treatment include radiation, chemotherapy, surgery, and targeted therapy.

4. Liver Cancer

If liver cancer is found too late, the chances of survival are minimal.

  • Symptoms include jaundice, upper stomach discomfort, lack of appetite, and weight loss.
  • Risk factors include hepatitis B/C, heavy alcohol consumption, obesity, and liver illness.
  • Treatment options include surgery, ablation treatment, radiation, and chemotherapy.

“Vaccination against Hepatitis B can significantly reduce liver cancer risk.” Dr. Sharat Chandra

5. Pancreatic Cancer

One of the deadliest tumors, generally found in its later stages.

  • Early symptoms include jaundice, stomach discomfort, nausea, and back pain.
  • Risk factors include smoking, diabetes, genetics, and obesity.
  • Treatment options include surgery, chemotherapy, radiation, and supportive care.

Rare Gastrointestinal Cancers

While the above cancers are most common, there are less common but critical gastrointestinal (GI) cancers:

  • Appendix Cancer—A rare cancer affecting the appendix.
  • Bile Duct Cancer—Also known as cholangiocarcinoma.
  • Gallbladder Cancer – Often adenocarcinomas affecting gland cells.
  • Small Intestine Cancer – Rarely develops in the duodenum.
  • Carcinoid Tumors – Neuroendocrine tumors affecting digestion.

These cancers require highly specialized diagnostic techniques and personalized treatment plans, which Dr. Sharat Chandra offers at his Hyderabad clinic.

Types of Gastrointestinal Cancer / GI Cancer

Gastrointestinal cancers occur in the digestive tract’s primary organs and can be divided into three categories as follows:

GI Cancer TypeCommon LocationPrevalence
Esophageal CancerEsophagusHigh in Asia
Stomach (Gastric)Stomach liningWorldwide
Colorectal CancerColon, RectumGlobal, 3rd rank US
Liver CancerLiver cells, metastasisAsia, West
Pancreatic CancerPancreasSevere worldwide
Others: GIST, NETsStomach, small bowelsRare, rising

Importance of Early Detection

Early detection greatly improves survival rates and provides a better chance for successful treatment.

Tips for Prevention & Early Diagnosis:

  • Regular screenings after age 40.
  • Maintain a balanced diet rich in fruits, vegetables, and fiber.
  • Avoid smoking and limit alcohol consumption.
  • Exercise regularly and manage body weight.

“Prevention is always better than cure. Simple lifestyle changes can reduce your cancer risk significantly.” – Dr. Sharat Chandra

GI cancers may be asymptomatic at first. Possible early symptoms include:

  • Difficulty swallowing
  • Abdominal pain or discomfort
  • Blood in stools or vomit
  • Changes in bowel habits
  • Jaundice (yellowing of skin/eyes)
  • Unintended weight loss
  • Persistent fatigue or weakness

Risk factors combine genetic, lifestyle, and environmental components, such as:

  • Family history
  • High intake of processed meats
  • Smoking, alcohol
  • Chronic GI disorders (GERD, Crohn’s, hepatitis)
  • Infections (H. pylori, hepatitis viruses)

Treatment Approaches at CancerCare

Dr. Sharat Chandra offers cutting-edge oncology care, including:

  • Surgical Oncology: For tumor removal.
  • Chemotherapy: To kill or slow cancer cells.

Latest Advances: Journal Research

The Journal of Gastrointestinal Oncology and leading GI cancer journals highlight:

  • Novel chemotherapeutic agents
  • Genetic and molecular classification of cancers
  • Outcomes of minimally invasive (laparoscopic) techniques
  • Advances in immunotherapy and targeted treatments

“Continuous research and clinical trials are improving the landscape of GI cancer care, offering hope for better survival rates.”

Gastrointestinal Cancer Survival Rates

Cancer Type5-Year Survival Rate (Approx.)
Colorectal Cancer65% – 70%
Stomach Cancer30% – 40%
Liver Cancer18% – 20%
Esophageal Cancer15% – 20%
Pancreatic Cancer10% – 12%

Survival rates vary depending on stage at diagnosis and treatment response.
