Neoplasia is the medical term for the development of a neoplasm, an abnormal cluster of cell growth that is more commonly known as a tumor. Ferrets may be more susceptible to some types of tumors at certain ages and are most likely to develop such tumors between ages four and seven. However, because the number of reports of digestive system neoplasia in ferrets is so low, information about the condition is limited.
There are two common types of tumor growth in the digestive system. The first is insulinoma, a condition in which tumors develop from pancreatic islet cells. Islet cells are a type of cell in the pancreas, an organ that secretes various enzymes and hormones into the body. The second is lymphoma, a condition in which neoplasms originate in the lymphocytes which are a type of white blood cell. Other tumor types that have been reported include tumors in the esophagus, intestines, salivary glands, and stomach. These other forms of digestive system tumors are less common than cases of insulinoma and lymphoma.
Symptoms of digestive system neoplasia vary depending on the location, size, and number of tumors present. Symptoms of gastrointestinal tumors (in the stomach or intestines) include sluggishness, weakness, partial paralysis, or difficulty moving the hind limbs, loss of appetite (anorexia), vomiting, weight loss and diarrhea. A gastric mass may also be evident due to a distended abdomen (when the belly feels full and tight). Pancreatic tumors may be asymptomatic, meaning that no symptoms are evident. In other cases, symptoms such as weakness, anorexia, vomiting, weight loss, and abdominal distension may be evident.
The causes and risk factors that lead to the development of tumors in the digestive are largely unknown. It is believed that an infection with the bacteria Helicobacter mustalae may predispose ferrets to develop gastric adenocarcinoma, a type of cancer that originates in the glandular tissues, or in this case, tissues lining the stomach.
One definitive way of diagnosing digestive system neoplasia in ferrets is via a histopathologic examination, which is the examination and analysis of bodily tissues with a microscope. There are other means of diagnosis, however. One of these is an exploratory laparotomy, a surgical procedure in which an incision is made into the abdominal wall in order to gain access to the abdominal cavity. With this procedure, a biopsy sample of tissue cells can be obtained for analysis and in some cases tumors may even be removed. Key areas to evaluate during an exploratory laparotomy are the pancreas, the lymph nodes in the abdomen, and the adrenals which are certain endocrine glands located by the kidneys. Additional diagnostic procedures may include urine analysis and X-rays to identify abnormal masses in the body.
Something that has to do with changes in the structure of the body as the result of cells that are diseased or abnormal in some way
The digestive tract containing the stomach and intestine
Small structures that filter out the lymph and store lymphocytes
A gland that aids in both digestive and insulin functions
The prediction of a disease’s outcome in advance
Anything having to do with the stomach
A term for a type of neoplasm that is made up of lymphoid tissue; these masses are usually malignant in nature
The tube that extends from the mouth to the stomach
The result of a malignant growth of the tissue of the epithelial gland.
The abdominal wall is a group of bones, muscles, and vital tissues that make up the wall around the organs in the abdomen. Inside these bones, muscles, and tissues is a cavity, and the cavity is what houses the vital organs found inside the abdomen. The abdominal wall is vital for protection of these organs.
Term used to refer to a condition of having a disease or affliction but not displaying symptoms of it.
Not being able to cause harm; the opposite of malignant.
The process of removing tissue to examine it, usually for medical reasons.
The space in the abdomen that holds the major digestive organs in an animal. Normally referred to as the area between the diaphragm and the pelvis. Also referred to as the peritoneal cavity.
