Question

Which are correct:

1. Computed tomography and magnetic resonance imaging detect cancers of internal organs.
2. Chemotherapeutics drugs are used to kill noncancerous cells.
3. α-interferon activate the cancer patients' immune system and helps in destroying the tumour.
4. Chemotherapeutic drugs are biological response modifiers.
5. In the case of leukaemia blood cells counts are decreased.

Choose the correct answer from the option given below:

Options

• B and D only

• D and E only

• C and D only

• A and C only

Answer 1

A and C only

Explanation:

MRI and CT scans are useful methods for identifying internal organ tumours. While MRI is excellent at producing precise images of soft tissues and organs like the brain and spinal cord, CT scans are especially useful for visualising the chest, lungs, and abdomen. Chemotherapeutic medications target malignant cells. The immune response against tumours is strengthened by a-interferons. Because WBCs proliferate uncontrollably in leukaemia, blood cell counts rise abnormally.
