Well, I looked at Michael's twitter, and I am happy to announce that Grandpa is out of surgery and on his way home. They managed to cut out all of the malignant parts of his cancer in about 5 hours of surgery. However, Grandpa is going to be in pain for the next couple of days due to the hole on his back. Apparently, he didn't need to be put to sleep for the surgery, so he was awake the whole time. Also there is going to be a discussion between Michael and Grandpa about going in next week to completely remove all of the cancer, so let's hope for the best. Right now, Grandpa seems to be recovering quite well. There are some pictures on Michael's twitter if you want to check it out.
