It is so good to hear from you here Barbara even though I keep up on FB.
The last thing you need is the stress of getting all your records together so you can get your scans and treatments at the one hospital.
I do not know how all this works in the US but wonder if it could be similar to what happens in my country.
My GP (General Practitioner - think PCP for you) gets updated via fax or letter for most treatments by specialists in and out of the hospital. I do ask for copies of pathology reports at the hospital but also ask my GP to print me a copy of any correspondence he gets.
I suspect it varies state by state with you as it does here but so far so good getting my information.
Love and hugs during this time.
