As I go over their many comments and questions on this site I become concerned that in some instances people do not know about their cancer. What I am referribg to is the failure of some of us to get copies of all the medical records. This includes copies of blood work including PSA tests, biopsy reports, scans, bone density reports, etc. It is vital that you have these reports, read them yourself and ask questions so that you understand all the information, and graph your PSA so you can see relative changes.
Put all of this information into a binder so that you have everything, in chronologic order, available to you. This way you will have these records already available when you go for a second opinion (don't give your copy of this binder away, give a copy) as well as the times you will need to recall your history.
Being an educated, smart patient who will extend their life requires understanding your cancer and the only way to do that is by getting all of your records, reading them and ubderstanding them. There should NEVER be a time when you say I don't know what my PSA doubling time is or was, or I don't know how many cores had how much cancer in them. All you need to do is go back to the binder and look it up.
