Hi, Dr. Ruth.



Can that really expalin it (not that I believe the original)?  It said 

"...when proper corrections are made for differences in oygen pressure [14], 

demographic and socio-economic confounding factors such as... cancer 

mortality _always increases_ with _increasing_ background exposures..."



I believe basal cell carcinoma is rarely fatal.  Thank goodness.  But I 

doubt it's another confounder that was not considered.  Melanoma perhaps?



Thanks and best regards,

Jim
