Best Medical Oncologist in Ahmedabad

Early warning signs of GI cancer often include persistent abdominal pain, unexplained weight loss, and changes in bowel habits such as chronic diarrhea or constipation. Other red flags requiring immediate evaluation by a specialist include difficulty swallowing (dysphagia), blood in the stool (melena or hematochezia), jaundice (yellowing of eyes/skin), and early satiety (feeling full after eating small amounts). As these symptoms can overlap with benign conditions like gastritis, a differential diagnosis by a certified medical oncologist like Dr Viraj Lavingia is crucial for early detection and better prognosis.

While a surgical oncologist focuses on the physical removal of the tumor, a medical oncologist manages the systemic treatment of cancer using chemotherapy, immunotherapy, and targeted therapy. In GI cancers (such as esophageal, pancreatic, and colorectal), a medical oncologist plans the roadmap for treatment—often administering neoadjuvant therapy (before surgery) to shrink tumors or adjuvant therapy (after surgery) to eliminate microscopic disease. Dr Viraj Lavingia in Ahmedabad, employs a multidisciplinary tumor board approach to ensure both medical and surgical strategies work in tandem for the best patient outcome.

Yes, genetic testing is highly recommended for families with a history of GI malignancies, as approximately 5-10% of these cancers are hereditary. Conditions such as Lynch Syndrome (HNPCC) and Familial Adenomatous Polyposis (FAP) can significantly increase the risk of colorectal and stomach cancers. If a patient is diagnosed with early-onset cancer or has a strong family history, he performs germline mutation testing. Positive results allow him to implement aggressive screening protocols for family members, potentially preventing cancer development entirely.

While no diet can guarantee cancer prevention, evidence suggests that lifestyle modifications can reduce the risk of recurrence for GI cancers. We advise patients to adopt a diet high in fiber, fruits, and vegetables, and low in red and processed meats, alcohol, and refined sugars. Maintaining a healthy body weight and staying physically active are also clinically correlated with better outcomes in colorectal and other GI cancer survivors. Post-treatment care involves a holistic plan covering nutrition, physical rehabilitation, and regular surveillance scans.

Immunotherapy has revolutionized GI cancer treatment by harnessing the body's immune system to recognize and destroy cancer cells, particularly in advanced stages. It is especially effective for patients with specific biomarkers, such as Microsatellite Instability-High (MSI-H) or Mismatch Repair Deficient (dMMR) tumors. As a medical oncologist specializing in precision medicine, I incorporate immune checkpoint inhibitors into treatment protocols where appropriate, often improving survival rates and quality of life for patients who may not respond to traditional chemotherapy alone.

Managing side effects is a cornerstone of effective medical oncology. We utilize prophylactic medications to prevent common issues like chemotherapy-induced nausea and vomiting (CINV), diarrhea, and neuropathy. By closely monitoring blood counts and organ function, we can adjust dosages or introduce supportive therapies (like growth factors) early. Our goal is to maintain the "dose intensity" required to kill the cancer while ensuring the patient remains strong enough to complete their full course of treatment without severe interruptions.
