I am very sorry your mother has been diagnosed with GBM. Sadly, it is a very deadly disease. My husband died from it four years ago. However, since he died, I have met some people who have actually survived for several years after their diagnosis. One man was diagnosed at age 45 and is still alive today at age 61. That is very rare though. Another man I knew lived for about five years after he was diagnosed and he had a pretty good life during those five years. He was a younger man also. My husband was 76 when he was diagnosed and he only lived three more months. With all of that being said, since your mother is relatively young and it seems they caught it “early”, she very well could live for several more years. It is a cancer though that grows back. With treatment, she will hopefully be able to keep it in check though. My husband did some radiation but in his case I think it killed him quicker. His platelets went way down after a few treatments so we had to curtail any further radiation. Also, the radiation will kill good and bad cells. The “good” cells will not grow back. I know people though who have had some good results with radiation. Also, he did chemo but he didn’t have the good receptors for it to be very effective. If your mother’s receptors are good, then chemo might help her. I hope this helps. I don’t want to be the bearer of bad news but those are some of the things that you will be dealing with. I will also say that you and your father need to just enjoy every moment you have with your mother. No arguing over the little things. None of that matters. Just enjoy them as much as you can while they are here. I wish you the best.
