Hello @clfa1949 I am very happy to hear you have gotten a team you can trust to give you the best care.
To expand on what @roch offered. There is probably a period of testing and gathering information and reviewing it, some that might be from the previous team and some new. This is important so that your team can help you make an informed decision about your treatment plan.
Honestly the best time once there is an agreed upon plan of action is as soon as you can get started, but alas there is usually some anxiety producing waiting in there too. Take heart that most cancers do not get out of control in that short time. I know this is hard, but I find it is better to try and remind myself that this is treatment free time and I might not feel this great once I start the next thing so I try to make the best of this time.
Do you have an appointment yet to discuss your treatment plan?
