Stomach cancer treatment in India

Stomach cancer is usually treated with surgery to remove part or all of the stomach, combined with chemotherapy given before, after, or both. India performs this surgery in high volume, including the complex lymph node clearance that determines how well the operation works.

Why staging comes before anything else

Stomach cancer is often found later than it should be, because early symptoms resemble indigestion. That makes accurate staging the first priority: it determines whether the aim is cure or control, and getting it wrong in either direction leads to the wrong treatment.

Staging normally involves an endoscopy with biopsy, a CT scan of the chest, abdomen and pelvis, and often a PET scan. Many centres also perform a laparoscopy, a short keyhole look inside the abdomen, because small deposits on the lining of the abdomen are frequently invisible on scans and change the plan entirely if present. If you have been offered surgery without that assessment, it is a fair question to raise.

The surgery, and what changes afterwards

Depending on where the tumour sits, part of the stomach is removed (subtotal gastrectomy) or all of it (total gastrectomy), and the digestive tract is then reconnected. Nearby lymph nodes are removed at the same time, and this part matters more than patients realise.

Ask about D2 dissection. A D2 lymph node dissection removes a wider, more thorough field of nodes than the simpler D1 approach. It is technically demanding and needs an experienced surgeon, and it is standard practice in high-volume centres across Asia. India's surgeons perform it routinely, which is one genuine reason to be treated somewhere that sees these cases often rather than occasionally.

Life after gastrectomy involves real adjustment. With a smaller stomach or none, you eat small amounts frequently rather than three meals, and eating too much or too quickly causes discomfort known as dumping syndrome. After total gastrectomy you will need vitamin B12 by injection for life, because the stomach produces the factor needed to absorb it. A dietitian should be part of your care, not an afterthought, and this is worth confirming before you choose a hospital.

Chemotherapy before and after

For most stomach cancers beyond the earliest stage, chemotherapy is given before surgery as well as after. Treating before an operation shrinks the tumour, makes complete removal more achievable, and treats cells that may already have spread. It also shows how the cancer responds, which informs what follows.

This has a practical consequence for travel: the full sequence runs over months, not weeks. Many international patients have chemotherapy started or continued at home and travel to India for the surgery itself. That is a reasonable arrangement and worth discussing in the consultation.

HER2 and targeted therapy

A proportion of stomach cancers carry extra copies of a protein called HER2, the same marker that matters in some breast cancers. Where HER2 is present, adding a targeted antibody to chemotherapy improves results. Testing on your biopsy is what reveals this, and if it has not been done, ask. Immunotherapy also has a role in some advanced stomach cancers, particularly those found to be MSI-high.

If it has spread to the abdominal lining

Stomach cancer sometimes spreads to the peritoneum, the lining of the abdominal cavity. In selected patients with limited spread, some centres offer cytoreductive surgery with HIPEC, in which heated chemotherapy is circulated inside the abdomen during the operation.

Be careful with this one. HIPEC is a demanding procedure that suits a narrow group of patients, and it is sometimes offered more widely than the evidence supports. If it is proposed to you, ask specifically why your case fits the criteria, and what the alternative would be. An honest surgeon will welcome that question.

How long you will stay, and what it costs

Gastrectomy means around a week to ten days in hospital, then recovery before flying, so allow roughly three to four weeks in India for surgery alone. Add to that the pathology report and a review with your surgeon, which determine what treatment follows. Do not book a fixed return flight before your surgeon advises on timing.

No part of it is a fee to us; the hospital pays us, so your bill is never marked up.

India is substantially less expensive than Western countries for gastric surgery, and the case volume advantage is real rather than only financial. You receive a written estimate covering the operation, hospital stay, pathology and follow-up before you commit, with no fee to us built in; the hospital pays us, so your bill is never marked up.

Questions patients ask

Can I live without a stomach?

Yes. After total gastrectomy the oesophagus is joined to the small intestine, and people live normally, though eating changes permanently: small frequent meals rather than large ones, and lifelong vitamin B12 injections. Most people adapt well within several months, and a dietitian makes a considerable difference to how smoothly that goes.

Is stomach cancer curable?

Yes when caught before it spreads beyond the stomach and nearby lymph nodes, with surgery and chemotherapy given with curative intent. Because symptoms appear late, many cases are found at a more advanced stage, where the aim shifts towards control. Your staging determines which conversation applies, which is why thorough staging matters so much.

What is D2 lymph node dissection, and do I need it?

It is a more thorough removal of the lymph nodes around the stomach than the simpler D1 approach, and it improves outcomes when performed by experienced surgeons. It is standard in high-volume Asian centres including India. It is a specific and reasonable question to ask your surgeon whether D2 is planned for your operation.

Will I have chemotherapy before surgery?

For most stomach cancers beyond the earliest stage, yes. Giving chemotherapy first shrinks the tumour, improves the chance of complete removal, and reveals how the cancer responds. Since the full sequence runs over months, many international patients arrange chemotherapy at home and travel for the surgery.

Can it be done by keyhole surgery?

Laparoscopic and robotic gastrectomy are performed in experienced centres and can mean less pain and a faster recovery. Whether it suits you depends on the tumour's size, position and stage. The thoroughness of the lymph node dissection must not be compromised for the sake of smaller incisions, so ask how your surgeon balances the two.

What reports should I send?

Your endoscopy report and the biopsy result, a CT of the chest, abdomen and pelvis, a PET scan if done, and HER2 testing if available. Include recent blood tests and your weight history, since nutrition affects fitness for surgery and is part of the assessment.
