I haven't gotten particularly personal on this blog, but today is the exception.
Last march my father started undergoing tests to examine the tissue that had grown into his esophagus after years of acid reflux. The tests showed patches of high-grade dysplasia. For the medically illiterate like myself, it is cancer without the kill-all-neighboring-cells attitude. Today he had surgery to have his esophagus removed.
According to the surgeon, the prognosis is excellent. Catching this in a very early stage made it so that all of the dysplasia could be removed, and there was no sign of any cancer outside of the esophagus. Everything looks like he'll make the full recovery in a couple of months that the doctor promised.
