Alkylating agents are used to treat various types of cancer, including leukemia, lymphoma, and multiple myeloma. These medications work by damaging the DNA of cancer cells, which prevents them from multiplying and growing. Alkylating agents come in different forms, including oral pills and injections, giving you options based on your treatment plan. Examples include cyclophosphamide, temozolomide (Temodar), melphalan (Alkeran), carmustine (Bicnu), and busulfan (Busulfex). You can discuss with your oncologist to determine the best form and medication for your condition.
