the point i am trying to make is that oxygen in any quantity can cause cancer, as does water as does anything, and with things that are rather popular, 100% of cancer are found in oxygen breather so there is a strong causality there, isn't it?
the point is that there is not point, and that you misuse decent sources and cross references data that has no correlation and call that a proof.
the thing is i really do not know if you are a really good troll or a complete trump-like nutjob, quite hard to make the difference in this day and age
