Notice that nowhere does it say anything about any cancer caused by
normal background radiation and in fact it says quite clearly that
"it is not clear if they have an increased risk of cancer because of"
being at high altitudes with even higer levels.

Do you understand the meaning of the phrase "beating a dead horse"?
