What is the primary purpose of chemotherapy in cancer treatment?

• A. To enhance the immune system
• B. To kill or slow the growth of cancer cells
• C. To improve quality of life
• D. To shrink tumors physically

Answer: (B)

The primary purpose of chemotherapy in cancer treatment is to kill or slow the growth of cancer cells. Chemotherapy drugs are designed to target rapidly dividing cells, a hallmark of cancer. Unlike normal cells, cancer cells proliferate uncontrollably, and chemotherapy uses this characteristic to disrupt their growth cycle. The cytotoxic nature of these drugs can affect cancerous tissues, leading to cell death or inhibiting further division, which is crucial in managing and treating cancer effectively. While enhancing the immune system and improving the quality of life are important aspects of comprehensive cancer care, they are not the primary actions of chemotherapy itself. Additionally, tumor shrinkage can occur as a result of chemotherapy's action on cancer cells, but the intent of the treatment is primarily focused on controlling the disease by killing or slowing down the growth of the malignant cells.
