Pancreatic Cancers In Dogs
Exocrine pancreatic cancers can be benign or malignant. Pancreatic adenomas are benign and non spreading tumors. The most common type of malignant tumor in the exocrine pancreas is pancreatic adenocarcinomas. There have also been a few other types of pancreatic cancers reported. The veterinarian will make a diagnosis based on blood tests, x-rays, exploratory surgery, or combination, as necessary.
Pancreatic Adenomas In Dogs
Benign pancreatic tumors can lead to organs moving out of position in the abdominal cavity. The displacement of organ may not cause any noticeable signs. In rare cases, the tumor may cause an obstruction of the pancreatic duct which causes the remaining exocrine pancreas to deteriorate. This can cause exocrine pancreatic insufficiency. Pancreatic adenomas are benign tumors and as such do not usually require treatment unless there are noticeable signs present. The tumors are usually found during surgery and as they appear similar to malignant tumors, the removal of the affected tissues of the pancreas is generally recommended. The prognosis for a dog with pancreatic adenomas is excellent.
Pancreatic Adenocarcinomas In Dogs
Pancreatic adenocarcinomas can cause the cancerous tissue to die if the tumor outgrows its blood supply. This can cause the are to become inflamed, and the animal may exhibit signs of pancreatitis. However, many dogs do not exhibit any signs until the late stages of the disease. Some dogs may show signs that would indicate pancreatic inflammation. Jaundice may be present if there is an obstruction of the bile duct. Some dogs may show signs related to the spread of the disease, such as bone pain, breathing difficulties or lameness.
Pancreatic adenocarcinomas are usually detected in the advanced stages of the disease and when the cancer has spread to to other areas. The veterinarian may attempt to remove the tumor surgically if the cancer has not spread. However, surgery is often unsuccessful as the removal of these tumors is very difficult. Chemotherapy and radiation therapy have not been completely successful in both human and animal patients suffering from pancreatic adenocarcinomas. The prognosis for dogs is very poor.
Pancreatic Abscesses In Dogs
Pancreatic abscesses can be a complication of pancreatitis. It is a collection of pus near the pancreas. The symptoms include depression, vomiting, diarrhea, fever, abdominal pain, dehydration and appetite loss. In some cases, it may be possible to feel a mass through the abdomen. Many dogs respond well to surgically draining the abscess. However, the veterinarian will assess each case individually to determine if the risk and expense of a surgical procedure would outweigh the benefits. The veterinarian will consider the specific condition of the dog, its overall health and other factors. Surgery may be recommended if there is explicit evidence of an enlarging mass, or a bacterial infection.
Pancreatic Pseudocyst In Dogs
Pancreatic pseudocysts are collections of sterile pancreatic fluid which are enclosed in a wall of tissue. The symptoms are similar to the signs of pancreatitis. Vomiting is the most common symptom. Ultrasound scans can show the cysts and they can be diagnosed by drawing out a fluid sample with a long needle. Drawing the fluid may also be used to treat the cysts. If the symptoms are persistent or the cyst does not decrease in size, then it may be necessary for the veterinarian to perform surgery to remove the pseudocysts.
