The cervical cancer
stage IVa is treated with high-dose internal and external radiation therapy & also with chemotherapy
(cisplatin with or without 5-fluorouracil
or other chemotherapy drugs) to increase the effectiveness of radiation therapy, or by itself to try to prevent the cancer from spreading to other areas of the body and to shrink the tumor in the known areas.
The Stage IVb cervical cancer may be treated with radiation therapy to relieve her cancer symptoms
or chemo alone.
It would be advisable if you also include your CT Scan / PET CT reports.
