It is often suggested that a blood test or urine test could a brain tumour, could it also detect the brain tumours. In fact both of these tests are not accurate in detecting brain tumours and should not be used in isolation. This is because brain tumours and cancerous growths in general have characteristics that are not common to normal tissue. Therefore any abnormal cell growths should be checked out with other methods and not rely on just one test.
There is no doubt that a blood test or urine test could indicate if a brain tumour exists. The problem is that these two tests do not distinguish between normal and abnormal cells in the brain. They work by looking for cell changes that could mean that a brain tumour exists, but there are many factors which could change these cell levels and these include; the type and number of brain cells in the brain, the thickness of the brain and the activity level of the brain. If there is any abnormality in the brain cells this could mean that there is a brain tumour and if there is nothing wrong with the cells then these tests will be positive.
Although it is highly unlikely, a blood test or urine test could find a brain tumour if the change in the cells is so slight that they are undetectable by an outside expert. This is because most brain tumours grow slowly and normally only a very small percentage of cells become abnormal over time. Therefore, unless the brain changes in size significantly there is little chance that a blood or urine test could detect the tumour. Of course, in the case of a suspected brain tumour there are treatments available which could remove the growth, such as excision or cauterization. These methods are highly effective and often successful, however they are not readily available and therefore these tests are not used in most cases.
There are a few other blood or urine tests that could detect the brain tumours, although they are not as widely used as blood tests or urine tests. The hemoglobin Glucomogram can be used to detect the glucomannanoma. A high level of Glucomannanoma is seen in people with anemia and this has been linked to the risk of developing brain tumours. The Hematological Nodular Disease test can also be used to detect the disease. Although it does not normally show brain tumours, it does have a high rate of success in detecting the disease.
Urine can also be used to detect the risk of brain tumours. This method is often used for people who have a high concentration of the protein uric acid in their blood. This test measures the amount of the acid in your blood and by monitoring the rise and fall of this level you can assess whether there could be a problem in the development of the brain tumours in the future.
Blood tests are not always accurate however, and they may miss the small ones that are produced by the brain. For this reason it is more common to see a combination of these methods to get an accurate answer to the question “could, blood or urine tests to detect the brain tumours?”. Sometimes the best answer is a mixture of tests; if a person has a particular symptom then it is worth considering testing both the physical health and the mental health. Other times the answer will come from one or two and this makes the overall assessment of the risk much more difficult to work out. In these situations the overall risk assessment method will be used and then a referral will be made to an appropriate pathologist for a more in-depth diagnosis.
