March 16, 2009 -- Question: How many external beam radiation treatments should I expect to receive, and will the doses increase throughout treatment?

Answer: The amount of radiation you receive depends upon the size of your cancer. Typically, a course of external beam radiation will last between seven and eight weeks, between 35 to 42 individual treatments. The radiation you receive each day is the same from start to finish. The dose though is cumulative as the treatment progresses.
