Great, this should be a sticky or pinned post, sure others will have additions and/or edits...

Thanks a million! I've printed this out and added it to my binder!


Pinned to right column

Took me a year+ to get my feet under me and still feel like I am on roller skates most of the time. Many tentacles and many directions equal a very complicated disease. Having said that the more I learn the less stress I have so I continue to read and follow this site.

Excellent! Thank you for posting.


Very helpful! Thanks for sharing!

Great work and long overdue! Years ago as a new member of Inspire I made a request to avoid using abbreviations, shortcuts, letters when responding to new members. especially! I was admonished by a well known advocate on that site that he didn’t have the time to spell out terms because he answered so many emails. Valid point so having this list of terms handy is a great resource!

The 4kin4kin4k.... Usual response to raised PSA


Fork n Psa .

Bluestein prediction -- tornadoes?


Thanks for your information very useful


Relating to doctors, I know what RO and a URO is but what is an MO? Many folks use this when referring to their doctors.


Medical Oncologist

Wow. No wonder I'm confused but this helps.
