Thanks for posting this. It is very interesting and important to know. I do remember that when Jim started to get blood clots and the thinners weren't helping to prevent them is when they started to look at cancer as the cause. I didn't really understand it then and am not sure if I do even now, but knowing that it could be a sign of cancer is important in diagnoising CC and other cancers that like to hide & lurk in the body. This is the first information I have seen on the subject.
