I am 'half' adopted. I never met my biological father. You are fortunate not to have any medical issues .... yet. I felt the same way until last month when I fell flat on my abdomen. Two days later, in great pain, I went to the outpatient clinic at a local hospital where they took a c/t scan, said I was fine but suffering from a bladder infection. They gave me antibiotics and pain killers, told me to call my own doctor for a follow up appointment and return to the hospital if the condition worsened. The following day, my docotr's nurse called to say my white blood cell count was off the scale and they feared it was kidney related. That night, the situationo worsened and I returned to the hospital. Another c/t scan with contrast indicated that one of my kidneys had a 'mass' on its side. The FIRST question asked was whether there was a history of kidney cancer in my family. (This runs in families) There is no history on my mother's side of the family but I have NO knowledge of my father's family. Next month, I am scheduled for surgery to remove the kidney.
I would hardly label this situation as 'dramatic'. It is life threatening.
Donor insemination does not screen for this condition!
Hope your surgery goes well.
I hope that you recover well from this. I understand fully that I may be in the same position as you someday.
