Costs can range from around $1,700 for a single treatment with conventional radiation techniques to more than $16,000 for four treatments using a system of radiation delivery called Cyberknife.
For example, proton therapy in prostate cancer cost $24,400 more than standard conformal radiotherapy (P < .001) and $11,000 more than 35 daily fractions of IMRT. The setting in which treatment is delivered also affects cost, particularly for prostate cancer.
