What is adjuvant therapy primarily used for?

Adjuvant therapy is primarily administered after primary treatment, typically to eliminate any remaining cancer cells and reduce the risk of recurrence. This approach follows the initial treatment, such as surgery, to address any microscopic disease that might not have been removed or detected. The goal is to enhance the effectiveness of the primary treatment and improve overall patient outcomes.

In contrast to the other options, which describe different treatment phases or combinations, the focus of adjuvant therapy is specifically on its application post-primary treatment. By emphasizing this point, it fosters a clearer understanding of how adjuvant therapy plays a crucial role in the overall management of cancer.
