I’ve been offered 15 or 5 too.
It’s not until May because I’m regional NSW and one of the machines at the hospital broke down 😩 so now there is a backlog of people.
I initially decided to have 15 but as time goes on I think the 5 may be an option too.
Be interesting to see the difference in outcomes.
The reason I chose 15 is because it has a lot more research behind it. The onc told me they are doing a 5 year study of the 5 round treatment however the results aren’t available til 2025.
I don’t want to make a decision based on wanting to get through it quicker and the recurrence rate is higher or more damage is done because it’s higher strength.
Sorry not helpful but you’re not alone in your decision making.
