Which of the following is NOT a characteristic of nonspecific immunotherapy?

The characteristic that is not associated with nonspecific immunotherapy is targeting specific tumor markers. Nonspecific immunotherapy aims to enhance the body's overall immune response against cancer without specifically targeting antigens associated with particular tumors. This approach broadens the immune system's activity to recognize and attack various cancer cells rather than focusing on distinct markers tied to specific cancers.

In contrast, other options accurately describe nonspecific immunotherapy. It does stimulate a large immune response, leading to a robust reaction against cancer. It can be effectively administered alongside other cancer treatments, such as chemotherapy or radiation therapy, to augment overall efficacy. Furthermore, it typically results in a broad response, as it primes the immune system to respond to a wide array of tumor cells rather than a select few. Thus, it fundamentally differs from specific immunotherapeutic strategies that concentrate on defined targets.
