Those who think diet and/or industrialization is a major cause of cancer point to less cancer in the developing or undeveloped world. But when you look you find that far from being less likely to get cancer - they are simply more likely to die young of other causes and more likely to die of cancer without it being diagnosed.
This Egyptian mummy had to wait a few thousand years for his diagnosis.
Do you wonder why some tissues are much more susceptible to cancer than others? Do you think dietary absorbed toxins are more likely to be deposited in such tissues - or is it that over time the constant cellular division of these tissues causes somatic mutations?
Whatever your belief about diet and toxins or phytoestrogens - it would be impossible to deny that tissues that undergo constant cellular replication during lifetime are much more prone to cancer than those tissues that do not.
The prostate, for example, is constantly undergoing cellular replication - and as men age - they are more likely to develop cancer of the prostate.
“...as men age - they are more likely to develop cancer of the prostate.”
I too believe this is true. There are some things though that have a bearing on cancer...Iodine, for instance. We often think that iodine is a thyroid issue. This is minimally true. Iodine is especially important in tissues like the breast and prostate. There is increasing evidence that if a woman has enough iodine in her breast tissue, she will not get breast cancer, and that if a man has enough iodine in his prostate tissue, he will not get prostate cancer.
There are several groups of indigenous people around the world that do not get cancer, and a commonality in these groups is high cesium in their diets. This has been extensively studied and cesium has been used successfully in curing cancer. Much of the work here was done by Keith Brewer, PhD.
These indigenous people do become subject to getting cancer same as the rest of us when they are no longer in their native environment and their diets change.
