Best Surgical Oncologists for Gastrectomy For Gastric Cancer in Mumbai, India

Gastric cancer is a malignant tumour arising from the stomach lining, most frequently of the adenocarcinoma type, which can grow through the stomach wall and spread to other organs if not detected and treated at an early stage.

Early gastric cancer often causes no symptoms, which is one reason it is frequently diagnosed at an advanced stage; when symptoms do appear they may include persistent indigestion, upper abdominal discomfort or pain, unexplained weight loss, loss of appetite, nausea, vomiting, difficulty swallowing, or blood in the stool or vomit. Advanced disease can lead to severe anaemia, significant unintended weight loss, jaundice, or a palpable abdominal mass. These symptoms overlap with many benign conditions, and their presence alone is not sufficient to establish a diagnosis of gastric cancer.

Diagnosis typically begins with a detailed clinical history and physical examination, followed by upper gastrointestinal endoscopy (gastroscopy) with tissue biopsy, which is the definitive method for confirming malignancy and identifying the tumour type. Once cancer is confirmed, staging investigations—including CT scan of the chest, abdomen and pelvis, endoscopic ultrasound (EUS), and in selected cases PET-CT or diagnostic laparoscopy—are used to determine the TNM stage (Tumour, Node, Metastasis) and guide treatment planning. Additional tests such as HER2 receptor status and other molecular markers may be assessed to identify eligibility for targeted therapies.

Treatment approach depends heavily on the tumour's stage, location, histological type, molecular profile, and the patient's overall health and fitness for intervention. Early-stage tumours confined to the stomach lining may be managed with endoscopic resection techniques, while more advanced localised disease is typically treated with surgery—most commonly gastrectomy (partial or total removal of the stomach)—often combined with perioperative chemotherapy. For metastatic or unresectable disease, systemic treatment with chemotherapy, targeted therapy (such as trastuzumab for HER2-positive tumours), or immunotherapy may be used with the goal of controlling disease and preserving quality of life; the most appropriate plan is determined by a qualified multidisciplinary oncology team based on individual assessment.

Non-surgical pathways play a meaningful role at several stages: chemotherapy and chemoradiotherapy may be used before surgery (neoadjuvant) to shrink tumours, after surgery (adjuvant) to reduce recurrence risk, or as the primary treatment when surgery is not possible. Targeted therapies and immunotherapy (including immune checkpoint inhibitors) are increasingly used for tumours with specific molecular characteristics. Palliative care, nutritional support, and endoscopic interventions for symptom relief are also important components of management for advanced disease.

Gastrectomy for gastric cancer may be considered only when it is appropriate for the confirmed diagnosis and the expected benefit outweighs the individual risks. The decision may depend on symptom severity, investigation results, previous treatment, overall health and the patient's goals. A specialist should discuss alternatives and recovery before any procedure is planned.

Gastric cancer is evaluated and managed by a surgical oncologist with expertise in upper gastrointestinal cancers, working as part of a multidisciplinary team that typically includes a medical oncologist, radiation oncologist, gastroenterologist, radiologist, and pathologist. Initial investigation and endoscopic management may be led by a gastroenterologist.

When comparing providers, look for a surgical oncologist or upper GI cancer surgeon with documented experience in gastrectomy and lymph node dissection for gastric cancer, affiliated with a centre that offers a formal multidisciplinary tumour board, pathology and molecular testing capabilities, and structured oncological follow-up including nutritional and rehabilitation support after surgery.

Share a concise medical summary, symptom timeline, previous diagnoses, investigation and imaging reports, procedure or biopsy reports where relevant, current medicines, allergies and related treatment records. Provide clear copies with translations when needed. The reviewing doctor may request additional information before giving an opinion.

Our care coordination team can review the initial information, help identify suitable doctors and hospitals, request a medical opinion where available, explain next steps and indicative cost information, and support practical planning before travel. A remote opinion does not replace an in-person examination or emergency care.
