Glad your Father is doing well. My husband was diagnosed March 2024 with stage 4 GMB. He is 58 years old and was completely healthy until he had what we thought was a stoke.. he was unable to talk and his blood pressure was super high.. (this happened on his birthday -Feb 2024) .. needless to say we had all the test done and was transported to a different hospital for testing.. Feb 14, 2024 we found out he had a brain tumor and later was informed it is stage 4.. due to the location he cannot have it removed.. he has been in treatment since March of 2024.. radiation that did nothing. and is taking chemo pills every 4 weeks for 5 days, IV treatment every 2 weeks. so far the tumor is stable (after radiation the tumor did get bigger) ...last MRI showed stable and slightly smaller... I hope and pray he can be around for a long time.. our daughter had a baby girl Sept 2024, so we are overjoyed about that.. life is strange sometimes ,but I know with faith and prayers, he can beat this.. . I will keep your Father in my prayers along with everyone else fighting this disease..
