What is the main goal of chemotherapy in the treatment of cancer?

The primary aim of chemotherapy in cancer treatment is to kill or inhibit the growth of cancer cells. Chemotherapy works by targeting cells that multiply rapidly, a characteristic of many cancer cells. This approach can effectively reduce the size of tumors, eliminate cancerous cells that have metastasized, and prevent the cancer from returning. By disrupting the cancer cell cycle or inducing cell death, chemotherapy can significantly impact the overall prognosis and treatment outcomes for patients.

While other options highlight important aspects of cancer care, they are not the main objective of chemotherapy. Promoting healthy cell growth is not directly associated with chemotherapy, which primarily focuses on destroying cancerous cells rather than encouraging healthy ones. Reducing pain and enhancing quality of life are vital components of comprehensive cancer care, often addressed through supportive measures and palliative treatments, but they do not define the specific goal of chemotherapy itself.
