Diagnosed With Simple Hyperplasia With Atypia, No Medication Taken. Will It Lead To Cancer ?

Hi. My mother was diagnosed with Simple Hyperplasia w/o atypia last May 2013, but hadnt taken any medication to solve it out. What was done to her was blood transfusion so as to replace the lost blood due to continuous bleeding. Now, four months after, the same scenario happens and we are afraid that she will undergo the same process, will be ok after and will eventually suffer from it again after another couple of months. What also concern us is the thought that her case would get worse and would lead to cancer. Any comment on this matter? Thanks.
