Context: Treatment Option Overview / Four types of standard treatment are used:
Surgery is a common treatment for CUP. A doctor may remove the cancer and some of the healthy tissue around it.
After the doctor removes all the cancer that can be seen at the time of the surgery, some patients may be given chemotherapy or radiation therapy after surgery to kill any cancer cells that are left. Treatment given after the surgery, to lower the risk that cancer will come back, is called adjuvant therapy.
