HI, welcome to HCM, I am Dr.Das
No. You have heard wrong information. Anisopoikilocytosis never indicates early leukemia
In peripheral blood film examination, the size, shape rbcs are important finding. If there is variation of these among the examined cells , it is called anisopoikilocytosis.
It indicates anaemia
As, there is mild anisopoikilocytosis, so there may be mild anaemia. You did not give the hemoglobin
One more thing , leukemia is the disorder of white blood cell
. Not the rbc.
However, the report does not indicates any early change of leukemia
