At the point where I had ten radiation treatments left I was told I needed to do a new simulation called a "boost" for SCC of the left tonsil. The explanation is, after 24 treatments they don't need such a wide beam, that they can now narrow the bean to be more direct onto the tumor. Sort of like a garden hose sprayer. The sprayer was wide open covering a lot of area, then they twist the nozzle and get a stronger narrower beam. Same dosage just more focused.
-Is this normal?
-Do the side effects change?
Thanks,
Rick
