You have published, Susan, but on your profile page so the only editor involved was you! You have to apply to write for a publication and if you’re accepted, you submit there and an editor reviews your work before publishing. For a long time, you could only submit to a publication from a computer, not a phone or tablet. That may have changed but I don’t know for sure because I haven’t tried.
I am sorry to know you have a new tumor. Is there nothing the doctors can do for you?
