I am 74yrs female, 5'5", 180lbs. Have low platelets 74,000 they have been dropping for the last 11 yrs, i am under the care of drs. i have no other medical problems. I play a lot of golf, go to gym sometimes and walk and lift weights, but not on a regular basis. MY mother died with leukemia. So of course i have some worries. How would know if you have myelodysplastic? I do not really have a diagnoise.
