Hereditary?

My nan died in March, she had Milo Fibrosis which (from what i know) is a rare form of Leukemia. She had very low blood pressure and Iron Deficiency anemia and (probably unrelated) Diabetes.

I've just been told that i have Iron Deficiency Anemia and also have a very low blood pressure (82/55). Due to the similarities, im just wondering if Milo Fibrosis is related to Anemia or low blood pressure and if it is hereditary.

I know my mum doesnt want me to know alot about my nans illness because of the similarities and probably doesnt want to worry me but contrary to her intentions, i am worried.

Help would be much appreciated x
