Surgeons continue their efforts to improve their techniques to operate colorectal cancers. They now have a better understanding of what makes colorectal surgery more likely to be successful, such as making sure enough lymph nodes are removed during the operation. Esophageal cancer usually begins in the cells that line the inside of the oesophagus. Pancreatic cancer begins in the tissues of your pancreas an organ in your abdomen that lies horizontally behind the lower part of your stomach. Colorectal cancer is cancer that starts in the colon or rectum. The colon and the rectum are parts of the large intestine, which is the lower part of the body’s digestive system. Pancreatic cancer is aggressive with few symptoms until the cancer is advanced. Symptoms may include abdominal pain, weight loss, diarrhoea, and jaundice. Treatments include surgery, chemotherapy, and radiation. Gallbladder cancer is a relatively uncommon cancer. If it is diagnosed early enough, it can be cured by removing the gallbladder, part of the liver and associated lymph nodes. Most often it is found after symptoms such as abdominal pain, jaundice and vomiting occur, and it has spread to other organs such as the liver.
