Hi my mother had myeloproliferative disorder or syndrome & a dr. tod me i will eventually turn into leukemia. it doesn't have to turn into l. rt?

Correct: The myeloproliferative disorders are polycythemia vera, essential thrombocythemia, and myelofibrosis. Of these three, only myelofibrosis is known to progress to leukemia, and only rarely. Did you mis-hear and the diagnosis is actually myelodysplastic syndrome? Perhaps, since myelodysplastic syndrome can turn into leukemia. Perhaps double-check and ask which kind of mpd she has.
