Thank you tlc356!

I did not see he was in India! You're correct in your CC and CCC terms, although they are abbreviations many use, so it's name doesn't mean much as there is no license or requirement to use such term, so many do. There are two organizations that are highly regarded, and those are members of the NCCN and NCI, that use designated CC or CCC, which you can find here. Another place I use is U.S. News Reports Best Hospitals, where one can probably find most all the institutions from the NCCN and NCI centers., I look under Cancer and ENT, which will show the best hospitals by rank in the U.S. for the best hospitals, then go to the hospitals cancer and otolaryncology web page, and find out more. It's not a difficult process. Still, I found the best hospital eventually, that wasn't on any of the listings, maybe now since it joined another hospital, and that was the reason I bypassed it from the beginning, but wound up there at the end! I only go in NYC where I live, and had treatment in NJ for Proton Therapy since none are in NYC, yet, though there

Son of Patient,

You're correct in your analysis! Each area has a maximum dose toxicity level, and radiation dosage is kept in those limits. I have permanent side effect, arm paralysis, from brachial plexopathy, from radiation due to a recurrence near the collar bone in level V. Usually they do not radiate level V or are kept to a minimum dosage, since tumors are less frequent there, but I was warned before of the possible side effect.

The material a mouth guard uses, maybe vinyl.

One should get a dental exam before radiation, and have teeth repaired, and if they can't be repaired, they should be removed. After teeth removal there should be 2-3 week, closer to 3, healing period before doing radiation. The dentist should fit a mouth guard.

Yes, tumors go through a cell cycle before death. I forget it mostly, but recall G0, G1, S G2 and M phases.

There can be many more radiation side effects some that are more common, less common and rarity. I thought there was a page on radiation, IMRT here? It's probably best to look there instead of me trying to repeat as much as I recall, but can help clarify any questions. I've read just about every page here on OCF. What I recall is another story lol!

Why are they removing the nasal tube now when one may need it during radiation? They can still use it during radiation on the inside of the mask. If one is put in after radiation has already begun, it should go on on the outside of the mask. I always had a peg tube, so that was no bother, mostly. Now, they don't like to use a tube until it's needed though.

When does treatment start?

I hope this helps, and read up here if you like!
