I'm not aware of any specific linkage between PCa and esophageal cancer. Never have seen such a mention in articles or research.
I've had four friends die of the second. All were smokers, none were known to have PCa, but considering the rapid run from diagnosis to death in each case, they were not looking for something else to worry about
