Which statement best describes chemotherapy?

Chemotherapy is best characterized by its use of drugs to treat cancer with the intention of curing the disease or controlling its progression. This approach is fundamental in oncology, as chemotherapy agents target rapidly dividing cancer cells, aiming to eliminate them or reduce their growth. The treatment can be utilized in various settings, including curative, adjuvant (post-surgery), neoadjuvant (before surgery), and palliative care, making it a versatile tool in cancer management.

While it can indeed be part of a comprehensive treatment plan for many cancer types, chemotherapy is not limited to specific cancers alone, as it can be effective across a wide range of malignancies. It is also important to note that chemotherapy is not a preventative measure against cancer, nor is it exclusively focused on pain relief. Therefore, the statement that accurately encompasses the purpose and application of chemotherapy is that it employs drugs to treat cancer with the goals of curing or controlling the condition.
