Current Question (ID: 16209)

Question:

Read the following statements about cancer and mark the incorrect ones: (i) Ionising radiations like x-rays and UV rays and non-ionizing radiations like gamma rays cause DNA damage leading to neoplastic transformation. (ii) CT scan uses non-ionizing radiations to accurately detect pathological and physiological changes in the living tissue. (iii) Antibodies against cancer-specific antigens are also used for detection of certain cancers. (iv) Some of the chemotherapeutic drugs are specific for certain cancers.

Options:

1. (i), (ii) and (iii)
2. (i) and (ii)
3. (iii) and (iv)
4. (ii) and (iv)

Solution:

Explanation: Ionising radiations like x-rays and gamma rays cause DNA damage leading to neoplastic transformation. CT scan uses ionizing radiations. Antibodies against cancer-specific antigens are used for detection of certain cancers. Some chemotherapeutic drugs are specific for certain cancers.
