5 Year Wait

I had been donating plasma for about a year when I went through the process of finding out I had cancer, and the removal of the tumor. During that time, I was not allowed to donate.
That was about 3 months ago that I stopped. Today, I went back with a note from the doctor stating I was cleared to start donating again. Apparently, however, they have a policy that dictates I wait 5 years before I can donate again.
Really? Even with a doctors note? Sheesh. Ok... I hope they remember me when I go back!
