“Do female beekeepers, who occasionally get stung, have lower incidences of this type of cancer?”
What a great question, unfortunately, I suspect that there are not enough female bee keepers to get a statistically valid sample size.
Its a logical question, probably one that will not have a definitive answer. For one thing, in the experiment, the collected venom was injected directly into the tumor. The necessary local serum levels of mellitin were not mentioned, and might be far higher than could be achieved by an occasional sting. But sometimes, these real-life retrospective studies (You’ve got triple negative cancer, what’s your occupation) can be suggestive.
