What Are the Available Types of Cancer Diagnostic Tests?


Cancer diagnostic tests play a significant role in the treatment of cancer. The several types of tests include- Complete Blood Count (CBC), Tumor marker tests, Circulating Tumour cell tests, etc. Here, also know about blood cancer symptoms and importance of cancer tests!


Cancer is a health condition in which the abnormal cells divide uncontrollably and destroy the tissues of the body. Cancerous tumor are malignant in nature and can spread to nearby tissues as well. Blood cancers are primarily of three types- Leukaemia, Lymphoma and Myeloma. Patients who have blood cancer generally experience normal symptoms like loss of appetite, fatigue, painful back, infection, breathlessness, chest pain, etc. If the symptoms left untreated, it can lead to severe health disorders like blood cancer. Therefore, performing cancer diagnostic tests are helpful in avoiding further complications.

How to diagnose cancer at an early stage?

To diagnose cancer at an advanced stage, the patient should take proper actions on cancer symptoms like abnormal bowel changes, rectal bleeding, persistent back problem, unusual coughing, etc.

What is the importance of Cancer diagnostic tests?

Cancer diagnostic methods help to locate the tumours accurately, stage the disease and determine a proper combination of cancer treatments for the patient. A type of cancer test, called Tumour Molecular Profiling especially helps the doctors to identify the right type of chemotherapy for the patient before treatment. During treatment, the tests help to track the size of the tumour, progression of the disease, response to the treatment and modify it accordingly. After the treatment, the tests help to take the follow-up by evaluating the recurrence of any symptoms. A cancer test name known as PET/CT 600 allows the doctor to detect small lesions that are present in various body parts and are subjected to movement such as – breast, lungs, colon and prostate.

What are the types of cancer diagnostic tests?

Some of the most important cancer diagnostic tests and methods include-

Complete Blood Count (CBC) - It is the most common type of blood test that measures the amount of different types of blood cells in a sample.

Blood protein test- Also known as Electrophoresis, it examines various types of proteins present in the blood. It also detects certain abnormal immune system protein called immunoglobulins. Other Cancer diagnostic tests and methods such as bone marrow biopsies are also used to confirm a suspected diagnosis.

Tumour marker tests- Tumour markers are chemicals that are prepared using tumour cells. Some of the important tumour markers include- prostrate-specific antigen (PSA) for prostate cancer, CA 125 for ovarian cancer, Alpha Fetoprotein (AFP) for liver, etc.

Circulating Tumour cell tests- These are recently developed blood tests that are used to detect broken cancer cells which float in the bloodstream.

What do the test results mean?

It is important to carefully interpret the results because of several factors which can influence the test outcomes. In addition, it is imperative to keep in mind that sometimes, noncancerous conditions can also lead to abnormal test results. The doctors should review the results several times to determine whether the levels are falling within a normal range.
