When a malignant tumor is found by the presence of a tumor marker, the level of marker found in the body can be monitored to determine the state of the tumor and how it responds to treatment. If the quantity stays the same during treatment it can indicate that the treatment isn't working, and an alternative treatment should be considered.
Canine cancer detection is an approach to cancer screening that relies upon the claimed olfactory ability of dogs to detect, in urine or in breath, very low concentrations of the alkanes and aromatic compounds generated by malignant tumors. While some research has been promising, no verified studies by secondary research groups have ...
Mast cell tumor on lip of a dog. Veterinary oncology is a subspecialty of veterinary medicine that deals with cancer diagnosis and treatment in animals. Cancer is a major cause of death in pet animals. In one study, 45% of the dogs that reached 10 years of age or older died of cancer. [1]
Dogs can develop many of the same types of cancer as humans. Many canine cancers are described with the same terminology and use the same classification systems as human cancers. [1] Mast cell tumors are the most common type of skin cancer in canines. [1] Lymphoma; Prostate cancer; Brain cancer; Hemangiosarcoma is a type of cancer that is ...
Venereal granulomata on a dog's penis. A canine transmissible venereal tumor (CTVT), also known as a transmissible venereal tumor (TVT), canine transmissible venereal sarcoma (CTVS), sticker tumor and infectious sarcoma, is a histiocytic tumor of the external genitalia of the dog and other canines, and is transmitted from animal to animal during mating.
Oocyte abnormalities can be caused by a variety of genetic factors affecting different stages in meiosis. [1] Moreover, ageing is associated with oocyte abnormalities since higher maternal age is associated with oocytes with a reduced gene expression of spindle assembly checkpoints which are important in maintaining stability in the genome.
It varies inversely with tumor grade; well-differentiated tumors secrete more CEA. CEA is elevated more in tumors with lymph node and distant metastasis than in organ-confined tumors and, thus, varies directly with tumor stage. Left-sided tumors generally tend to have higher CEA levels than right-sided tumors. [16]
Cytokeratin 5/6 (CK5/6) is a biomarker that has emerged as a valuable tool in distinguishing epithelioid pleural mesothelioma from metastatic adenocarcinoma. In a study comparing its effectiveness with other markers, CK5/6 showed high sensitivity, staining positively in 92% of epithelioid pleural mesothelioma cases.
