Gastrointestinal cancers range from oesophageal cancers which may cause difficulty in swallowing to cancers of the stomach, small bowel, large intestine, rectum and anal canal. The symptoms can vary from acid reflux disease, dysphagia to bleeding in the stools, and unexpected weight loss. Pancreatic cancers remain a therapeutic challenge for surgeons.
Gastrointestinal cancers are often detected at an advanced stage and may therefore need chemotherapy/radiation therapy before or after surgery.
Dr. Kamran Khan has extensive training in treatment of upper gastrointestinal esophageal, gastric and colorectal cancers. Few centers perform radical or minimally invasive surgeries for these cancers i.e. laparoscopic and robotic.  See www.cancersurgeryindia.in for further information on these.
