The number of fractions (treatment sessions) required ranges from 5 to 38 fractions. They are given every weekday, or every second day in the case of patients having only 5 fractions. This means that treatment times range from 2 to 8 weeks, excluding treatment planning. The actual fraction administration only takes a few minutes, but you can expect to be at the centre for 20 to 40 minutes each day, and you are free to explore Prague for the remainder of your day.
