I am so sorry that your son has join our ranks. The important thing to remember when you hear statistics and predictions for longeviety with this disease are those predictions are based on the average patient that is over 60 at diagnosis.
Someday through the national registry, better numbers might be available but really aren’t now.
I recommend that you also check out the Aplastic Anemia-Myeloydysplastic Foundation website. http://WWW.aplastic.org and the leukemia society website. They also have links to clinical trials and the centers of excellance for MDS.
There are more and more options for patients but first you need to know what type he has. Nutrition is extremely important as is exercise. Be sure and get a nutrionist and a trainer for him to work with, in addition to medical personnel.
We are all here whenever you need us. Good luck
