He is in his 2nd MRI right now, then off to surgery for what is characterized as a simple low risk bypass procedure to alleviate the pressure, and if lucky might be able to biopsy the tumor.
They will test the CSF for markers that might indicate what type of tumor we are dealing with in case the biopsy chance doesn't pan out.
He will probably be released from the hospital on Monday, and the next steps will be determined by the lab results.
Turns out that the tumor is not totally inaccessible, so if it comes to it, surgery remains an option, but a risky one.
Mark has now mostly been briefed in, he wanted to know what he was up against. His Science Olympiad-learned college level of anatomy means he understood the neurosurgeon and he wanted to see the scans and knew what he was looking at. Amazing kid.
He is taking it all pretty well, joking with his younger siblings. There are still plenty of possible bad outcomes, but now we are seeing a few scant rays of light shining on possible outcomes that are a little bit north of hopeless.
Your prayers and prayer chains, words of encouragement, and offers of help are priceless and move me to tears. Prayers remain the best and most needed help. Thank you, and God bless.
