Those studies demonstrated caffeine can block BCC skin tumor formation, but the researchers say more studies are needed to know for sure that caffeine is responsible, particularly in humans.
One glaring question researchers were left with after the study's completion is why coffee nor any caffeinated dietary source doesn’t appear to have the same anti-cancer effect on the two other forms of skin cancer-- squamous cell carcinoma (SCC) and melanoma, the most deadly form of the disease.
Han says it is possible previous studies looking at SCC and melanoma cancers were just too limited to have found an association between caffeine consumption and those cancer types.
“As the study participants are followed for a longer time, the number of cases of these conditions is likely to increase. We may be in a position in 10 years’ time to better address this issue,” he said.
