Surgery for a Cancer of Unknown Primary
Surgery is used to treat many types of cancer, if they are found at an early stage. But because cancer of unknown primary (CUP) has already spread beyond the site where it started, surgery is less likely to be helpful.
Surgery may be an option if the cancer is found only in the lymph nodes or in one organ, where the surgeon may be able to remove it all. However, there’s still a chance that the cancer may be somewhere else in the body. If you are considering surgery as a treatment option, it’s important to understand how likely it is to help you.
The type and extent of surgery will depend on where the cancer is and how extensive it is. If surgery is used, it may be followed by radiation therapy and possibly chemotherapy to try to kill any remaining cancer cells in the body.
