The other day I heard about a man whose family history was riddled with colon cancer. His father and uncles and other relatives all had suffered from the disease, and it was clear that he, too, had that genetic disposition. When he and his new wife decided they wanted to have children, they were naturally concerned.
For them the solution lay in a new process called PGD (pre-implantation genetic diagnosis) that would allow them to avoid the tragedies that had befallen others in their family. Doctors harvest a number of eggs from the female, fertilize them with the sperm of the male and produce embryos that can be tested for any number of things, including the genes that produce certain diseases.
