Which option is NOT one of the three main cancer treatment categories?

• A. Surgery, chemotherapy, radiation therapy
• B. Biopsy, surgery, systemic therapy
• C. Cryosurgery, chemotherapy, brachytherapy
• D. Hormones, Surgery, Radiation therapy

Answer: (B)

The main cancer treatment modalities are surgery to remove or debulk the tumor, chemotherapy to kill cancer cells systemically, and radiation therapy to destroy cancer cells with ionizing radiation. A biopsy is a diagnostic procedure used to confirm cancer and determine its characteristics; it does not treat the cancer. Therefore, any option that includes biopsy is not one of the three main treatment categories. In this case, the option that lists biopsy alongside other terms does not represent a primary treatment category, making it the choice that is NOT one of the three main cancer treatment modalities.
