Welcome to Connect, @phulwanik0611. Chromic Myelogenous Leukemia is often very slow to develop and without the need for immediate treatment. With treatment, if required, patients can live a full and healthy life.

We have a number of members in the forum who also have CML like @pam62 @ilahi @ortina2023, whom you’ve already spoken with in this discussion: https://connect.mayoclinic.org/discussion/does-anyone-have-cml/

Your doctor is going one step further to confirm your diagnosis with running genetic testing to see if you have a mutated gene that may be causing your CML. I also noticed that you’re pregnant from another comment you made. From reading this article below, it explains that if you do have this gene, that it is an acquired mutation, not one that is passed down from parents to children. So hopefully that will give you a little peace of mind with your pre-natal depression. That’s a lot to be grasping at one time!

Here’s a very good article on CML for you to read through:

Is this your first pregnancy? Have you discussed your depression with your Ob/gyn?
