What is the main use of antineoplastic agents?

Antineoplastic agents are specifically designed to treat malignant tumors or cancer. These medications work by targeting rapidly dividing cancer cells in the body, halting their growth and proliferation. The primary objective of using antineoplastic agents is to eliminate or reduce cancerous cells, thereby managing the disease effectively.

In contrast, other options reflect different medical purposes: pain relief is typically provided by analgesics, hypoglycemia is managed with glucose-raising agents, and cholesterol levels are addressed through lipid-lowering medications. None of these roles pertain to the specific function of antineoplastic agents, making the choice to treat malignant tumors the correct focus for their use.
