Photo examples

Nodular basal cell carcinoma
Nodular basal cell carcinoma. The white area in relation to the tumor represents morphea type basal cell carcinoma

Treatment and surgical margins

Depending on the surrounding skin and type of basal cell carcinoma, several non-surgical treatment options can be chosen, including:

  • Cryotherapy
  • Radiation
  • Curretage
  • Aldara
  • Photodynamic therapy

Surgical margins

  • Nodular BCC: 2-5 mm margin depending on how easy the tumor margin is to identify.
  • Superficial BCC: 4-5 mm margin. Use magnification to identify tumor margin.
  • Infiltrating and morphea: 5-7,5 mm and the use of freezing histology to be sure the excision is radical.
