Read the following passage and answer the following question.
Cancer is one of the most dreaded diseases of human beings and is a major cause of death all over the globe. More than a million Indians suffer from cancer and a large number of them die from it annually. The mechanisms that underlie development of cancer or oncogenic transformation of cells, its treatment and control have been some of the most intense areas of research in biology and medicine. . Normal cells show a property called contact inhibition by virtue of which contact with other cells inhibits their uncontrolled growth. Cancer cells appears to have lost this property. As a result of this, cancerous cells just continue to divide giving rise to masses of cells called tumors. Transformation of normal cells into cancerous cells may be induced by carcinogens. Radiations cause DNA damage leading to neoplastic transformation.Cancer causing viruses called oncogenic viruses have genes called viral oncogenes. Cancer detection is based on biopsy and histopathological studies of the tissue and blood and bone marrow tests for increased cell counts in the case of leukemias. Techniques like radiography, CT and MRI are very useful to detect cancers of the internal organs. The common approaches for treatment of cancer are surgery, radiation therapy and immunotherapy.

What is the full form of CT?(Question 3)

Computed Tomography

The correct answer is Option (3) –Computed Tomography

Techniques like radiography (use of X-rays), CT (computed tomography) and MRI (magnetic resonance imaging) are very useful to detect cancers of the internal organs. Computed tomography uses X-rays to generate a three-dimensional image of the internals of an object. MRI uses strong magnetic fields and non-ionising radiations to accurately detect pathological and physiological changes in the living tissue
