Interresting article
Loved your article, but you should at least give the oncologists credit that there are cancers that can be cured: Hodgkins Disease has a 90% chance of definite cure in stages I and II, and I know of quite a few patients with stage IV who have a 30 years survival history (had Hodgkins Disease stage IIa myself 11 years ago and did some extensive research in this field).
The same figures are true for cancers caused by papilloma virus (uterus, throat).
But if I continue your way of thinking, there is one thing absolutely certain: 100% of mankind will die of cancer unless they are not killed by something else. Cancer is mainly a phenomenon of old age (setting aside the genetical disorders like breast and colon cancers as well as leukemia and myelomas in young people who definitely are genetical phenotypes) so the probability to die of cancer is very high. Statistically, and I can only give you figures for Switzerland where I live and have the statistics in memory, the probability to die of cancer is 30%, 40% of death is due to cardiovascular diseases and 30% for other reasons.
There is only one thing you can count on: life is ended by death for everyone.
