In a recent study, scientists determined, through the assessment of patients smoking histories, that there are connections between smoking cigarettes and non-melanoma skin cancer, including basal cell carcinoma (BCC) and squamous cell carcinomas (SCC). The results showed that smoking was associated with non-melanoma skin cancer, and that the risk increased with the quantity of smoking that had been done. It differed between men and woman however. In men smoking was modestly associated with both BCC and SCC, but in women it was strongly associated with SCC but not BCC. They are unsure of why there is a difference but are continuing their research in this study.
