I was battling bone cancer since 1991, first they tryed removing the tumor, and knee replacement, and tibia bone transplant.  Then in 1994, the cancer came back...I had 12 weeks of radiation. Because of all the radiation I had, I did not have much range of motion in the leg. I was limited to what I could do.The cancer came back in 2001, and I KNEW that I had enough of dealing with trying to save the leg, so I had it amputated.
