@DarkScribe I think if you are going to engage me, at least demonstrate an understanding of data and epidemiology. My “theory” isn’t really a theory. It is backed by solid epidemiologic data. Here is the data from the National Cancer Institute of the NIH. What it shows is that cancer rates for individuals <20 and 20–49 are static, while those for individuals between 50–64 have risen slightly, and >65 have the highest increase. Notice too that the actual incidence for older individuals >50 is much higher than for the younger cohort. Put another way, cancer incidence by age at diagnosis is highest for the oldest population.
As for the rest of your comments, they are factually incorrect or incoherent ranting. However, in the interest of thoroughness, let me debunk them, one by one.
Why are cancer rates increasing among children and younger women if it is related to our good fortune in living longer? They are not Or, show me the hard data.
Why are animals that are NOT experiencing increased lifespans suddenly becoming affected with diseases and cancers that have never before been prominent among them? Many animals suffer from extreme inbreeding, which results in selection for aberrant tumor suppressor genes. The same thing occurs in humans. Humans with Familial adenomatous polyposis or inherited retinoblatoma develop cancers owing to inherited mutations.
If you were correct, then we would be seeing an increase in cancer and chronic disease primarily among the aged population, not throughout the general population. As I showed above through (gasp) actual statistics, we are.
Walk through any oncology ward and look at the occupants, they are not mostly old. I’m not sure what your definition of old is, but cancer is much more common in the elderly. Cancer wards are full of relatively younger patients (50–75) because they can tolerate and are more willing to undergo the treatment. Older patients are neither good candidates nor willing to go through complex chemo/radiation regimens.
Why are we getting increasingly frequent reports of “cancer clusters” often among younger women and children if the increase is only related to longevity and not negative aspects of modern lifestyle? These occur frequently, but often statistical analysis shows that these are nothing more than blips (i.e. not real). Occasionally, they can be tied to an environmental carcinogen, but this is very rare, and certainly wouldn’t explain your “hypothesis”.
France, Denmark, Germany and Japan all seem to be consistent in results and often in conflict with US research. Do you think that is has to do with law regarding autonomy in research? Really? I’m not sure what you are saying here, but it is well known that US biomedical research is at the forefront. Why else would the majority of Nobel Prizes in chemistry and physiology-medicine be awarded to Americans? Are the Swedes in on it too?
I am suspicious of US research and claimed findings. Ok. Here is the cancer incidence data from Germany, Denmark (taken from here) and Japan (taken from here). All show a dramatically higher incidence of cancer with increasing age. I guess they are in cahoots with the US research mafia too?
In the future, if you want to debate an issue, come prepared with actual data. Until then, your views can be best described as highly-speculative opinion.
