Hi welcome to Healthcaremagic
For the basal cell carcinoma
, surgery is the treatment available the disease will be confirmed by biopsy
.. they will remove not only the lesion, but 1cm of the normal skin around the ulcer..this is to prevent the recurrence of tumor
.. its good, the repeat biopsy did not have any residual report of cancer... your husband must stop smoking
... smoking is not related to flap or surgery...
Hope I have answered your question..
