Breast Cancer - Right Knee Enchondroma

I am breast cancer survivor (2 yrs).  I just have been diagnosed with a right knee enchondroma. I know my doctor has reassured me that this is not malignant however, after been a cancer patient it is hard not to be worry.  Also what it's surprising for me is the size of this tumor 3.2cm x 2.4cm 2.3cm.
What are the chances of this tumor turning onto something malignant? Should I be worry?

Hi there!

Enchondromas are benign lesions and not to be anything to worry about regardless of the size and do not require any specific management unless symptomatic.
Hope this is helpful

Take care!
