I'll tell you a Truth here. When I was 27 I had a node taken (surgically) from my groin area. Then I went back to work. I got a call from the doctor's office (while at work)... what they said is "it was not malignant... however, there was something 'strange/wrong' with your blood tests... we have sent the sample to Walter Reed. " Because my father, uncles, aunts, brothers etc... were all in the military... I knew that wasn't right ~ I mean ~ Then, silence... no questions answered EVER ... to this day.
