RE: NCRP 136 / Immunology, DNA repair, cancer...

Hey Gentlemen,

I'm not a doctor....and I don't play one on T.V. either.... but what the heck does the imune system have to do with resistance to cancer? It is not a virus or bacteria.....it is the unchecked , abberant growth of cells which overtakes the surrounding tissue and hence the damage. The imune system has little to do with preventing contracting cancer or slowing/stopping the spread of it within the body. Angiogenisis inhibitors can be used to prevent the cancer from obtaining a blood source to sustain it's self and suspend any metasticised cancer migrations from gaining sustenance. From what I understand a tumor sends out a chemical which causes new blood vessels to branch off and feed it (angiogenisis). As for the ill effects of exposure to ionizing radiation ; Pish! Considering the levels of gamma required to cause temporary blood gas changes are sky high compared to the NRC's annual dose limit for the general public and rad workers how the heck do we suppose we have enough imper!

!

ical data to draw any substantial conclusions? I have a lifetime dose of over 20Rem and I am healthy as a horse. Heck...I hardly ever catch a cold. I have been smoking 2 packs of cig's a day for 20 years yet my lung capacity is 116%. Here's what I'm getting at...(AT LAST!)Data is a funny thing. If you look at it long enough and from the right angle....you can extrapolate ANY conclusion you desire. Beware those whom supply us with raw data and even more wary of those who would interpret it for us. We have a long road ahead of us before we are absoluteely sure of ANYTHING. Be patient and give yourself a break. You're all doing great but it takes time. Maybe put your heads together rather than butt them?

I cannot fault your logic, but can you meet me half way, or reach out and 

offer a helping hand to a struggling amateur? I have heard MDs suggest the 

immune system is involved somehow with cancer. Furthermore, I have read 

that some cancer research attempts to stimulate the immune system. Am I 

totally wrong or just partly wrong?
