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

The main goal of using chemotherapy in cancer treatment is to control tumor growth and alleviate symptoms. While achieving a complete cure for the patient is an important outcome, it is not always possible, especially in advanced-stage cancer. Chemotherapy is often utilized to shrink tumors, which may help reduce pressure or alleviate symptoms caused by the tumor's presence.

In addition to controlling the malignancy, chemotherapy can significantly improve the quality of life for patients by reducing symptoms, managing pain, and addressing issues caused by cancer's progression. It serves multiple purposes: enhancing the chances of successful surgical resection when combined with surgical treatment, potentially reducing tumor burden before surgery, and treating cancers that are systemic in nature.

Other options, while relevant in certain contexts, do not capture the primary goal of chemotherapy as accurately as controlling tumor growth and alleviating symptoms. For instance, delaying surgical treatment may not be a goal of chemotherapy; instead, it can sometimes be used to make surgical interventions more effective. Although enhancing radiation effects is a valid point in terms of chemoradiation protocols, the overarching aim remains the management of the disease and enhancement of patient well-being.
