Thanks for the glossary post...very helpful. I have a question about terminology for either Gary or Mark.
What is the unit of measurement called for our rads. The RO said I had 7000 ???'s, which was a max life time dose,beyond which irreparable tissue damage begins. I wish I had asked more at the time but I think it was not IMRT because the cancer was poorly differentiated and the saliva glands are now fried.
I'll watch for your post, Thanks, Fran B.


SCC Base of tongue diag. April 04 Stage IV, mets to rt. neck multiple nodes 35 rads+8 boosts First recurrence Jan05. Rt.rad neck dissection Feb02/05. Recurred with bone mets in neck July 05.

Hello Fran, The basic unit of radiation absorbed dose is the amount of energy (joules)absorbed per unit mass (kg). This unit, known as the Gray (Gy), has replaced the unit of rad used in the past (100 rads = 1 Gy; 1 rad = 1 cGy).

The amount of radiation absorbed by the tissues is called the radiation dose (or dosage). Before 1985, dose was measured in a unit called a "rad" (radiation absorbed dose). Now the unit is called a gray (abbreviated as Gy). One Gy is equal to 100 rads; one centigray (abbreviated as cGy) is the same as 1 rad.

70Gy or 7000 RAD (7000 cGy)is generally considered to be the "lifetime" dose for head and neck. This may not be exactly true because of advances with IMRT, where retreatment may still be possible.

I think I got that right, Gary might add more or correct me.

A valient effort, and a posting that should be put in the frequently asked questions. I had to laugh, being an ex-military person at FUBAR, with the substitution of the first word from the more common F word, and the omision of SNAFU which almost always accompanied FUBAR in military jargon... Situation normal, all F*#$%d up.

SNAFU is there and many of us know how to properly pronounce it.

NIATC???....OIC!

I stand corrected. (ISC) I should have RTFM/list better. We should start our own acronyms, as you can see (AUCS) from my addition here. I vote for GTBOTSOTG (Glad to be on this side of the grass) as the first new bastardization of the King's English that we should add here at OCF. After all, they put the word bling in the dictionary this year, what is becoming of our language!!!
