What is the result of using adjuvant chemotherapy?

Adjuvant chemotherapy is employed after the primary treatment of cancer, such as surgery, to eliminate any remaining cancer cells that could lead to recurrence. The primary goal is to target and treat residual disease or undetectable metastasis that may not have been removed or detected during the initial treatment. By administering chemotherapy in this context, the likelihood of cancer returning is significantly reduced, improving the overall prognosis and survival rates of patients.

The other options do not accurately reflect the purpose of adjuvant chemotherapy. It does not increase the risk of metastasis nor specifically target cancerous tissues exclusively; instead, it works systemically to address potential microscopic disease. Additionally, while managing pain may be part of cancer treatment, adjuvant chemotherapy is not primarily aimed at this aspect, but rather at preventing recurrence by addressing any lingering cancer cells.
