How can i be sure that my basal cell carcinoma on my forehead has been cured completely after surgery?

Pathology reports: The best way to know if the skin cancer has been entirely removed is by careful pathologic evaluation. Though the "path report" isn't always correct, it is rare that a skin cancer will return in the same place if the report states that it has been entirely removed.

The pathology report: When a basal cell is removed and sent to pathologist for evaluation of the margins. If the margins were clear , that means the basal cell was removed completely.

Clear margins: Only a small margin of normal tissue is necessary when excising most basal cell carcinomas. Either a frozen section pathology exam or permanent sections will confirm this. If the margins are clear, the chance of recurrence is very low.
