Hi @Meg1112, the waiting is the worst. I had several non related non cancerous things picked up on my initial scan, it's apparently quite common. I also have a tiny nodule on my lung which is being monitored, the oncologist was fairly unconcerned about it and said they see them fairly often, and they are usually caused by an old infection or environmental things, but they need to keep an eye on it if it isn't clear what it is. I've had 2 scans and another in September just to check it hasn't changed. So far mine hasn't, even during chemo, which is good, so if it's still the same in September I won't need to be scanned again. Hopefully yours is something similar.
The initial scans and tests can be pretty overwhelming, but it does settle down once that's all done and you have a plan in place.
If you have access to a McGrath Nurse you should contact them, they have been a great help through my journey.
