The Captain has a tumor.
Turns out his mange may have just saved his life. So far so good on the grape consumption but the little ball that developed on his ear about 3 months ago (or at least that's when we noticed it) is a sort of skin tumor that can be malignant. They will remove it next week along with the surrounding tissue. It will be tested further to see exactly what it is. If it is malignant, hopefully they will have removed it all and he will be ok - better yet, let's hope it's benign. But still, the Captain has a tumor.
I'm starting to question the month of July.
