Hi! My mom was diagnosed with Glioblastoma Multiforme Stage 4 in May 2008. She had craniatomy in June 2, this year and was advised by the doctor to undergo radiation and chemotheraphy. Doctor said mom would survive for six months utmost without any treatments, one year with radiation, and two years with chemotheraphy. The family decided not to go through the treatments per request of my mom.
In the first four weeks after her surgery she was okay, could talk and walk, and eat whatever she likes.
Five - six weeks after, her legs became smaller and could hardly walk without assistance. Seven weeks after operation she was bedridden and could hardly eat. We still continued her steroids and other medicines, but she continued becoming weak.
On her 8th week after surgery, mom was on her worst condition. So weak.. it was too hard for the family to witness her sufferings.
Finally, she gave-up. Mom died two months after her surgery without any treatments. She died just end of this August.
But don't lose hope, miracles still do happen. Just keep on believing. Give your father the best love he deserves.
God bless!
