The primary objective is to assess whether verteporfin PDT can completely eliminate multiple BCCs. Eligible subjects will have at least 3 BCCs. Study subjects won't know which treatment they have been been assigned to - this is done randomly (like flipping a coin). After study treatment, the BCCs in each subject will be closely observed and toward the end of the study all will be surgically removed and examined to verify response to study treatment. Safety will be assessed by testing blood samples before and after study treatment, and analyzing adverse events and skin reactions to the study treatment.
