If the cancer has spread and it cannot be removed, the doctor may do surgery to relieve symptoms. During this operation, the doctor will cut the gallbladder or bile duct and sew it to the small intestine. This is called biliary bypass. During these procedures, the doctor may make the catheter drain through a tube to the outside of the body or the catheter may go around the blocked area and drain the bile to the small intestine. In addition, if the cancer is blocking the flow of food from the stomach, the stomach may be sewn directly to the small intestine so the patient can continue to eat normally.
Chemotherapy uses drugs to kill cancer cells.
Chemotherapy may be taken by pill, or it may be put into the body by a needle in the vein or muscle. Chemotherapy is called a systemic treatment because the drug enters the bloodstream, travels through the body, and can kill cancer cells outside the pancreas. Biological therapy searches for ways that the cancer tissue is different from normal pancreas tissue, and tries to get the body to fight the cancer. It uses materials made by the body or made in a laboratory to boost, direct, or restore the body's natural defenses against disease. Treatment by stage Treatment of cancer of the pancreas depends on the stage of the disease, and the patient's age and overall condition.
