How Doctors Diagnose Cancer Through Laboratory Testing Services

There are several laboratory testing centers available today. These testing services are used to detect different diseases of your body. Several tests are performed in these laboratories for the particular type of diseases in order to detect the problem. You can do your blood tests online through several websites. 

Before giving any diagnosis of cancer to their patient, doctors would require him/her to go through some tests. There are laboratory testing services that doctors – and patients – rely on in regards to diagnosing and even preventing cancer from happening. These laboratory testing services include blood tests, tumor markers, and urinalysis.

The first of these clinical laboratory testing services are blood tests. These can help detect the amount of red blood cells, white blood cells, and platelets in a patient's blood. Red blood cells are for the transportation of oxygen to the different parts of the body, while platelets are the body's protection from bleeding and bruising easily. When a blood test shows that there is a larger amount of white blood cells in the body than usual, it may mean that there is an infection. White blood cells are responsible for fighting any infection that occurs in the body.

If doctors would rely on the results of blood tests alone, then there would be hundreds of doctors diagnosing patients with cancer even if the patient is only suffering from a bout of colds. This is why other laboratory testing services are conducted in order to make sure that the patient really has cancer, and not some other illness.
