    And, this will all be available on your smartphone or other mobile device!

    What Do You Need to Do?

    The message board you're used to will be closing in the coming weeks. While many of your boards will be making the move to our new home, your posts will not. Want to keep a discussion going? Save posts you want to continue (this includes your member profile story), so that you can re-post them in the new message boards.

    Mass vs cyst
    An_243004 posted:
    My sister just had her mammo done 3 days ago and was told that she has mass on her left breast. Prior to her mammo, she had seen her oncology doctor (my mom and her sister both had breast cancer and was told to see an oncologist for preventive measures). What is the difference between a mass and a cyst? Is one cancerous than the other?
    rachael67 responded:
    Sorry about this worry. A "mass" means something appears that isn't considered normal and bears investigation. Neither terms mean cancer and neither means it isn't... Yes, limbo sucks big time! She will need further testing most likely to get a definitive answer.

    She will be in our thoughts. Keep us posted.

    Always listen for what is in the silence and see what is invisible...That's where miracles hide, and it can make all the difference!
