In his driveway four years ago, Joseph Khoury discovered he couldn't move his legs or get out of his car. Only 24 years old then, he had no idea he was stricken with non-Hodgkin's lymphoma. "We had a lot of red flags of cancer: not sleeping, muscle pains, sweating when he slept. But we just thought he was out of shape and overweight," said his wife Tracie, a chiropractor, who at the time was finishing school.
