I am a member to this forum since my husband was diagnosed with CML in July

of 2006. I read often and post seldom---but had to write and say THANK YOU

for this glossary....wow, some of us really needed that!

Thanks much,

Cervera

Tracey thank you so much for all your information I was dx on Oct.06.

and I don't post to much but I read everything everyone posts I am

thankfull and greatfull for all of you it takes some of the fear of the

unknown away .

THANKS AGAIN

Thanks Tracey,  I figured it out myself, which is rare.  Mine is old too,

perhaps the same one, I did not look it up.  but a lot of the terms can help the

newbies, so I thought I'd send it.  I sure wish i had it 14 years ago, wish I

had this group then too......Bobby

Subject: [ ] CML Glossary

There's a CML glossary in the files section of the website but it's

really, really old.

To get to it, just click on " files " on the left menu of the main page. Then find

the glossary and click on it.
