Final answer:
Combination chemotherapy is the type of therapy given in larger doses but less frequently. It involves the use of multiple drugs administered simultaneously to target rapidly dividing cells, including cancer cells.
Step-by-step explanation:
The type of therapy given in larger doses but given less frequently is called combination chemotherapy or polychemotherapy. This treatment involves the use of multiple drugs given simultaneously to effectively target rapidly dividing cells, including cancer cells. By administering higher doses of drugs during each treatment session, the therapy can be less frequent. Combination chemotherapy has proven to be successful in many cancer treatment regimens, and it is commonly used in conjunction with other treatments.
