That would be some super interesting co-evolution. My guess is "no", but only for armchair reasons - way outside my area of expertise. My understanding is that mouth and throat cancers are realy uncommon before middle age, so the moderate but ubiquitous fitness loss from the cold is probably worse, evolutionarily speaking, than the substantial but infrequent fitness loss from dying of cancer later in life. It seems plausible, however, that the mutations which make cells cancerous might also impair their response to viral infection. /armchair
