Some of the other members may be able to dig up some posts by one of our esteemed members Zufus. Sadly Bob (Zufus) is no longer with us but he used DES for many years to keep his cancer at bay (had to fight tooth and nail to get it). He had a great deal of information on its use. After all the other hormone therapies had failed, DES kept him rolling along for a long time. If memory serves me rightly possible blood clots could be problematic (controlled carefully by appropriate thinners) and he had a good doc who monitored any side effects closely.
