Is chemotherapy the same is radiology?(14 posts)

Is chemotherapy the same is radiology?Sprint-Nick
Oct 4, 2003 4:31 PM
I was reading through Lance's book and was just curious is chemotherapy the only form of radiation treatment used to kill tumors? Do all result in hair loss, lethargy and those side effects? Why is health tissue not killed by it?

Thanks,
Nick

Chemo is drugs; radiation is like a high tech ray gun shooting at the tissue. Hair loss and lethargy are from the drugs. So is the nausea. Chemo does have side effects, but you are balancing the damage being done to the cancer cells against lesser evils.

Chemotherapy = drugs. Radiation = xrays, proton beams, implanted pellets, etc.

No chemo and radiation are not the same, as the first two responders mentioned. That being said, radiation can cause some bad side effects too, depending on where it's used. Basically it destroys and weakens healthy tissues, so you have to be careful where you point those beams.

Chemo is very much toxic to all cells, healthy and cancerous, but most of them are targeted to certain processes that cancer cells perform more often, like mitosis (reproduction) and protein and DNA synthesis, because they are generally reproducing much faster than nornal cells. But still, you get immunosuppression most of the time and the nausea/vomiting/etc. because cells in the GI tract and the immune system replicate pretty frequently even in a healthy person.

Which does affect VO2Max and cadence, but I would still use Michelin Pro Race tires if I were on chemo. (just keeping it on the cycling board, ya know). :)

No, more like systematic doping. nmQubeley

It's the exact opposite of doping--it destroys red and white blood cells, to the point where any physical activity is exhausting and bacteria from anything and anyone around you can be life-threatening.

I've taken care of a lot of cancer patients, and none of them have said "wow, thanks for the chemo--I feel great!" Cancer patients DO, however, get EPO and sometimes blood product transfusions, but only to the point where counts are "less abnormal," not even average.

So, if you're trying to make up a reason why Lance ISN'T the greatest cyclist of our time, pick another one because you clearly have no idea what you're talking about.

My friend's mom just went through Chemo recently, I know how it works. Thanks for letting me know you are qualified, make me feel better.
As far as whether LA is a greatest cyclist or not, did I say anything about him?
Go for an easy ride, you got WAY too much stress in you..

PISS OUT!
Sorry, man...DrPete

Sorry... you just sounded like one of those "Lance somehow used his cancer to dope" folks, and I just have a hard time with that. I just see way too many sad endings with cancer that I get all offended when someone tries to discount a survivor, and I thought from your message that you were trying to do that.

No hard feelings...

DrPete
No hard feelings here either, glad it's clear. nmQubeley

I went through 40 session of radiation treatment a little over a year ago. The only hair I loss was directly in the area of treatment. Still no hair there.

My only side effects are the little ink dots they used to mark the radiation area. 8 years later, that's the only reminder. Of course, I'm still missing my right testicle:-)

Yeah, I've got the dots. Won a couple of bets with em. People who know me know I would never have a tatoo. When I tell them I have 12 tatoos they don't believe me. Of course the tatoos are just dots but I have won a couple of cold ones! As for the serious side of this, I actually had more tiredness from my radiation than from my chemo. The main recurring problem that I have is trying to lose the weight I gained with the steroids they gave me while I was on chemo. 15 years later and I'm still trying (not too hard) to lose the weight.

Dr. Nick Riviera assured me that it would eventually grow back.

I like to say I'm not crazy, just half nuts.

TCer myself.
