I am extremely grateful as I write this column for several reasons. First I listened to my father's doctor who requested that my brother and I have our colons checked due to our family's history with colon cancer. Typically doctors recommend that such a test is not necessary until one reaches 50, but in cases where family history indicates a higher risk doctors recommend beginning at 40. In my case, my great grandmother died from colon cancer and my grandmother died of pancreatic cancer. While both were well over 70 when they got sick, the danger was there.
