Answer:
1. Cancer can be treated with a single chemo drug, but often several drugs are used together.
Explanation:
It can be used in a certain order (called combination chemotherapy) or in certain combinations. Different medications which work together in various ways will destroy more cancer cells. The risk of the cancer being immune to a chemical treatment can also be developing.
The only treatment you need is sometimes chemo. Chemotherapy is used more often in the course of surgery, radiation or both. And sometimes it is used with other medications, including behavioral therapy, hormone treatment or immunotherapy. Chemo may be used, for example, to shrink a tumor before an operation or radiation therapy. Neoadjuvant therapy is the chemo used in this way.
Following surgery or radiation, the remainder of the cancer cells in the body can be destroyed. Chemo is known as adjuvant therapy in this way.
In other medication, such as targeted therapy for certain cancer cell targets and immunotherapies that support the immune system to combat cancer, it can kill cancer cells with other types of medication.
