Final answer:
Option A. True, anti-cancer drugs can induce mutations in normal cells, which can lead to the development of secondary cancers, although this is a risk weighed against the immediate threat of the existing cancer.
Step-by-step explanation:
True: Anti-cancer drugs can produce cell mutations that may lead to the development of other cancers. Cancer therapies, including chemotherapy and radiation, can cause DNA damage in normal cells, which sometimes results in mutations. While these treatments are designed to destroy cancer cells, they can also affect normal cells and potentially lead to secondary cancers. This is because cancer generally results from the accumulation of DNA mutations, leading to uncontrolled cell proliferation and the ability to metastasize.
For example, certain chemotherapeutic agents are known to be mutagenic or carcinogenic, and patients treated with these drugs may have an increased risk of developing a new, secondary malignancy. This is a known risk, but it is weighed against the immediate threat of the existing cancer. It's important to understand that not all patients who receive these treatments will develop secondary cancers and that the benefits of treating the primary cancer often outweigh these risks.
