I lost my sweet boy Smaug a couple days ago to a cancer called Chondrosarcoma (a bone cancer) He had a swollen finger amputated on February 4th, and this is what the biopsy results came back as. I was stroking his back on Thursday and noticed that he had a giant hard lump where his elbow hits his side. It was not there last month when x-rays were done. It ended up being the same cancer. It was coming from a rib. It grew really fast, and was the size of a grape. They could have done more surgery to remove it, put we decided to let him go because it would have been really hard on him, and there was a good chance another one might have grown somewhere else. He wasn't eating very well, and he was hardly moving around. I sure will miss my sweet boy. He brought me much comfort as I am living with my own bone cancer called Multiple Myeloma.
