I really like the way you share your experience. It is quite pleasant to follow, except that as @alexanderalexis I got lost with all the acronyms ;)
To come back to the topic, is GTD thus considered as a cancer? I assume so as chemotherapy is used to treat it. But then what are the chances of success for the treatment? Thanks in advance for answering.
Cheers!
Actually cancer drugs are often used for other conditions. One example is a chemotherapy drug called methotrexate that's often used for autoimmune conditions, since chemo drugs often dampen the immune system. See here for more detail.
