Gastrointestinal Cancer

Cancers of the food pipe (oesophagus), stomach, colon, rectum, liver, gallbladder and pancreas. Their early symptoms imitate everyday digestion problems — which is exactly why persistent ones deserve testing instead of another course of antacids.

The short answer

Indigestion, acidity and altered bowel habit are usually harmless. They stop being routine when they persist beyond a few weeks, keep returning, or come with any red-flag sign: difficulty swallowing, black stools, blood in stool, vomiting, unexplained weight loss, or new jaundice. Those signs call for an endoscopy or scan — simple tests that either reassure you completely or catch a cancer while it is still operable.

Symptoms of gastrointestinal cancer

  • 01Food sticking on the way downDifficulty swallowing solids — the classic sign of oesophageal cancer
  • 02Persistent indigestion or upper-abdominal painLasting weeks, or new after age 45
  • 03Black, tarry stools or blood in stoolBleeding anywhere in the digestive tract — never normal
  • 04A change in bowel habitNew constipation, diarrhoea or narrow stools lasting more than three weeks
  • 05Unexplained weight loss or loss of appetiteFeeling full after a few bites, clothes loosening without dieting
  • 06JaundiceYellow eyes or skin, dark urine, pale stools — needs same-week attention

How these cancers are found

Endoscopy — a camera examination of the food pipe, stomach or colon — is the definitive test for most GI symptoms, done as a short daycare procedure. A biopsy taken during it settles the diagnosis. CT scanning stages the disease: how far it extends and whether surgery can remove it. None of this requires admission, and none of it should wait months.

How GI cancer is treated at CoreOnco

Surgery remains the curative core for most GI cancers — removing the involved segment of bowel, stomach or oesophagus with its lymph nodes. Many patients receive chemotherapy before surgery to shrink the tumour, after it to lower recurrence risk, or both; the sequence is decided in a tumour-board discussion, not by habit.

For rectal and some other tumours, minimally invasive and robotic approaches mean smaller cuts and faster recovery. Where a stoma (bag) is possible or necessary, we say so before the operation, explain whether it is temporary, and train you and your family in its care — it is far less limiting than most people fear.

What does GI cancer treatment cost?

Privately, major bowel, stomach and rectal cancer operations typically run ₹1.5–4 lakh, with 6–8 chemotherapy cycles where needed at ₹15,000–60,000 per cycle depending on regimen. Where a stoma is created, supplies cost roughly ₹2,000–5,000 monthly — a real number families deserve to hear before surgery, not after.

For PM-JAY-eligible families, covered surgery, chemotherapy and admission are cashless at our network hospitals, with the full written figure settled before admission.

Common questions

I have acidity for years. Should I worry?
Long-standing, stable acidity that responds to treatment is common. What needs testing is change: symptoms that stop responding, weight loss, trouble swallowing, vomiting, black stools, or onset after 45. Any of those warrants an endoscopy, not another antacid.
Is colon cancer curable?
Caught before it spreads, colon cancer is one of the more curable major cancers — surgery alone cures many early cases. This is why blood in the stool or a persistent change in bowel habit should never be dismissed as piles without an examination.
Will I need a permanent bag (stoma)?
Usually not. Most bowel cancer operations rejoin the bowel; when a stoma is needed it is often temporary, protecting the join while it heals. For low rectal tumours a permanent stoma is sometimes the price of cure — if that applies to you, you will know before surgery, never after.
Is treatment covered under Ayushman Bharat?
Yes — GI cancer surgery, chemotherapy and admission fall under PM-JAY packages for eligible families. Eligibility is checked and pre-authorisation completed before admission.
