Immunotherapy is also known as biotherapy and is typically used in combination with which treatments to enhance the body's immune response?

• A. Surgery or physical therapy
• B. Chemotherapy or radiation therapy
• C. Vaccines
• D. Antibiotics

Answer: (B)

Immunotherapy boosts the immune system’s ability to recognize and attack cancer cells. It’s commonly used with chemotherapy or radiation therapy because these treatments can increase the amount of tumor antigens exposed to the immune system and reduce tumor burden, making cancer cells easier for immune cells to target. The immunotherapy then enhances and sustains the immune response, leading to a stronger and longer-lasting attack on remaining cancer cells. Other options don’t align with this approach: surgery or physical therapy don’t activate systemic immunity; vaccines are another form of immune activation but aren’t the typical pairing described here; antibiotics treat infections, not cancer.
