Which statement about chemotherapy is true?

Chemotherapy is indeed characterized by the use of drugs specifically designed to destroy cancer cells or inhibit their growth and proliferation. It acts on rapidly dividing cells, which includes not only cancer cells but also some normal cells. This method can be a crucial component of cancer treatment, employed either as a primary treatment or in conjunction with other therapies such as surgery or radiation.

While the other options present facts that are inaccurate regarding chemotherapy, the emphasis on its capability to eliminate or control cancerous cells makes it a central aspect of oncology treatment protocols. Understanding this core functionality is essential for grasping how chemotherapy integrates with the broader treatment landscape for cancer patients.
