My dad just received a call from his doctor and he didn't ask any questions nor does he quite understand. He found out on Friday from a biopsy that he has esophageal cancer. He had a CT scan this morning and the doctor called and told him it's spread to his lungs and kidneys, but he doesn't know how much, what stage, or anything. In fact, he thinks it's only a little on his lungs. This is bad, isn't it?
