Hi John. I'm sorry to hear about your reoccurance with the tumor. I'd like to share my mother-in-laws story with you. It is somewhat similar but not exactly.
During her childhood years (ages 1- 10) my mother-in-law would have seizures. Doctors did have her on medication for them and they were kept at bay. Back then there was not the technology to find out exactly what was going on. Fast forward to age 16...it was time for her to drive and docs said she couldn't unless when off the seizure meds she did well.
They did all the tests they could do back then and took her off them. She did well so she got her license. She is now 46. From 16 to 46, she had no signs or symptoms of the cancer,tumor,etc. One night 3 months ago she passes out, is taken to the hospital and they find a tumor the size of a tangerine. Emergency surgery is done and 2 weeks later we find out she has GBM.
How do things seem to happen like this? Why weren't there any signs before it was too late? I know what you're thinking...and I can't explain it as she had no deficits leading up to her dx and currently for the most part now other than tiredness from treatment and some agitation issues. It's so horrible....I hope you keep beating this monster..God bless~
