is it spreading

During this time period, the medicals decided to send Marie for a PET scan. That stands for positron emission tomography. Don't ask me to explain how it works. It's way over my head. The way I understand, it is a mapping of the inside of a body. If there are tumors growing, then that area would light up, showing activity. They were looking to see if the tumor was spreading. If there were microscopic cells in the spinal fluid, the possibility existed, for the tumor to spread anywhere down the spine. That test came back negative for any spreading. That was a good thing. The tumor seemed to be confining itself to the same general area of the brain. As long as they continued to treat the tumor, as it showed up, and there was no evidence of spreading, then it was reasonable to assume, that this condition was curable. Sure, there would be cognizant issues, and the quality of like would be reduced, but so what. Life would continue.
