Steroids can be a mixed blessing. Steroids will not cause the cancer to spread. Steroids are used to control swelling, but usually when the swelling is due to a tumor pressing on vital organs such as the brain or spinal column.

The down side to steroids is water retention, insomnia, and personality changes. Long term use can cause brittle bones.

Since this therapy is not a standard protocol for treatment of head and neck cancers, I would ask more questions of the doctor.
