Questions: 83. An antineoplastic drug called doxorubicin is used for the treatment of leukemia. However, one of the serious side effects of the medication is urinary bladder cancer. This potential for causing cancer is called: A. Teratogenicity B. Carcinogenicity C. Drug Toxicity D. Idiosyncratic side effect

The answer is B: Carcinogenicity.

Explanation for each option: A. Teratogenicity: This refers to the potential of a substance to cause birth defects during fetal development. It is not related to causing cancer. B. Carcinogenicity: This is the potential of a substance to cause cancer. Since the question states that doxorubicin can cause urinary bladder cancer, this is the correct term. C. Drug Toxicity: This refers to the harmful effects of a drug when taken in excessive amounts or over a prolonged period. While drug toxicity can cause various adverse effects, it is not specifically about causing cancer. D. Idiosyncratic side effect: This refers to an unusual or unexpected reaction to a drug that is not related to the dose and is not a common side effect. It does not specifically refer to the potential to cause cancer.

Summary: The potential for doxorubicin to cause urinary bladder cancer is called carcinogenicity.
