Hi Tonyb,
I am one of the forum volunteers. I had a STC almost 3 years ago, and since then I have not had any active cancer, although I am tested every 3 months for signs of it returning. It is laying dormant so does not give me any symptoms and I am not on any kind of maintenance treatment.
The STC itself is not a pleasant procedure, but for me it was entirely worth it and Im glad I had it. It has to be a personal choice, but for most people it is a life-extending treatment. I would suggest you discuss it with your medical team. However, as you say you are at the upper age for which treatment is offered, so if you decide to not have it now, you might not be given another opportunity in the future.
This is a scarey time for everyone that goes through it, but there is support available at every stage. If you need any more information as to what STC entails, and what effects it has, so that you can make an informed decision, please let me know. Don`t forget that we have the peer buddy service where you can talk on the phone or on zoom with someone who has already gone through it if that would help.
Let us know what you decide to do.
regards, Tony
