There are many different types of cancer that the body can suffer from and pancreatic cancer is one of the most common. The surgery that is most commonly used to treat this kind of cancer is referred to as 'Whipple surgery'. This has proven to be one of the most effective ways to reduce or remove the cancer from the infected area. However, if the surgery is not successful you will normally find that the symptom of thickening of the stomach lining or abdominal wall is a sign that the cancer is returning or has already done so, so unfortunately this is rarely good news to receive. If you do find that you have these symptoms you will normally find that they will be accompanied by vomiting and a large reduction in your appetite. However, this is not always the case with every single patient. The key to giving yourself the best chance of looking after your health in this situation is to act fast and always listen to whatever your doctor advises you to do. They will normally provide you with a strict diet to stick to that will help your stomach to process the food and hopefully reduce the nausea and vomiting. Thickening of the stomach lining does not always mean that the cancer has returned but generally that is the case so if your doctor or surgeon gives you this diagnosis it is extremely important to take heed of any advice that he or she gives you and follow it to the letter.
