Cancer is a disease that requires an integrated approach to diagnosis. It is possible to make such a diagnosis reliably only after a complex of studies. But conventional tests can cause suspicion of this disease. Besides, those are easy to do in almost any laboratory. It is a laboratory diagnostic that helps determine which organ has potential problems, and then purposefully look for their cause. So what tests to do to identify bowel cancer and accurately assess the presence of the disease.
A malignant tumour is an actively growing tissue that requires a large amount of “building material” and energy. It actively consumes substances necessary for the growth of the organism and releases metabolic products, including those with toxicity. In other words, the main changes associated with these two processes. And, the results of blood tests would show that.
Specific changes rarely appear in the urine test in the case of cancer. But any deviations in the results is a reason to conduct a more thorough examination.
Blood in the urine is an early symptom of bladder or urinary tract cancer. But it can also occur with urolithiasis or glomerulonephritis.
Seven indicators are most important for the diagnosis of cancer in the biochemical blood test:
In oncology, blood coagulability significantly increases. The risk of thrombosis of large vessels and the formation of microthrombus in capillaries also increases.
A blood test for markers of cancer tumours makes it possible to suspect oncology at an early stage, to assess the dynamics of the disease, to determine in time a relapse or the appearance of new metastases, to evaluate the effectiveness of treatment. We figured out in a general sense, what tests to do to identify bowel cancer. But there is more focused research.
Tumour markers are such substances that associate with the vital activity of a tumour. Those do either not show in the body of a healthy person or are there in minimal quantities. We know more than 200 such substances. But not all of them are easy to detect in medical practice equally successfully.
Cytology has the highest specificity of all methods of laboratory diagnosis of cancer.
It is almost always possible to make a diagnosis and determine the type of tumour reliably using cytology. The sensitivity of this method depends on the type of cancer. It also depends on the quality of the process of taking the probe for the study. For example, if the cancer cells did not get into the washings, the study will give a negative result, although the tumour itself may continue to develop.
After an initial examination, the doctor will decide what tests to do to identify bowel cancer. Excellent prevention of the intestinal oncology is colonic irrigation.
