What total radiation dose was given to a patient during 25 fractions of treatment?

To determine the total radiation dose given to a patient during 25 fractions of treatment, it's essential to consider the typical dose per fraction used in radiation therapy. In many treatment regimens, the common fractionation schedule involves delivering a specific dose per fraction over a set number of sessions.

In this case, if we assume a standard fraction of 300 cGy (which is commonly used), the total dose can be calculated by multiplying the dose per fraction by the number of fractions. Therefore:

Total Dose = Dose per Fraction x Number of Fractions = 300 cGy x 25 = 7500 cGy.

This calculated total aligns perfectly with the choice indicating a total dose of 7500 cGy. This amount reflects a treatment plan designed to ensure that the tumor receives sufficient radiation while minimizing damage to surrounding healthy tissue. Therefore, the selected total of 7500 cGy is the correct answer based on standard radiation therapy practices and calculations.
