2025 Human Health and DiseaseCancer Detection and Treatment Medium Question 7 of 121 in Human Health and Disease

Which are correct:
A. Computed tomography and magnetic resonance imaging detect cancers of internal organs.
B. Chemotherapeutics drugs are used to kill non-cancerous cells.
C. $\alpha$-interferon activate the cancer patients' immune system and helps in destroying the tumour.
D. Chemotherapeutic drugs are biological response modifiers.
E. In the case of leukaemia blood cells counts are decreased.
Choose the correct answer from the option given below:

A B and D only
B D and E only
C C and D only
D A and C only

The answer is D.

Solution

Statements A and C are correct.

CT and MRI scans are standard techniques for detecting internal neoplasms (A). Biological response modifiers like $\alpha$-interferon stimulate host immune defense against cancer (C). Chemotherapy selectively targets rapidly dividing neoplastic cells, not non-cancerous cells (B is false), interferon is the biological response modifier (D is false), and leukaemia features abnormal overproduction of leukocytes (E is false).
