3.4 Blood Tests
Blood tests are an essential tool in the diagnosis and monitoring of canine cancer. These tests provide valuable information about a dog's internal health by analyzing blood cells and other components.
One of the primary purposes of blood tests in cancer detection is to assess complete blood count (CBC). The CBC provides details on red blood cells, white blood cells, and platelets. Abnormalities in these counts can indicate the presence of cancer or its progression. For instance, anemia, often characterized by a decrease in red blood cells, may suggest bone marrow involvement or blood loss associated with certain tumors. Elevated white blood cell counts can also be indicative of inflammation or infection, which might accompany some types of cancer.
Additionally, blood tests help evaluate biochemical parameters such as liver and kidney function. Cancerous cells can release substances that affect these organs, leading to abnormal enzyme levels in the blood. Elevated levels of alkaline phosphatase (ALP) or alanine aminotransferase (ALT), for example, may suggest liver involvement, while increased creatinine and urea nitrogen can indicate kidney dysfunction.
Blood tests are also crucial for monitoring the effectiveness of cancer treatments. By tracking changes in blood cell counts and biochemical markers over time, veterinarians can assess whether a treatment regimen is working or if adjustments are necessary. Regular blood testing allows for early detection of any side effects or complications that may arise from chemotherapy or other interventions.
