Cutaneous areas at risk for non-melanoma skin cancer

The National Comprehensive Cancer Network (NCCN) guidelines (squamous cell carcinoma [1] and basal cell carcinoma [2]) classify high-risk lesions by size and location, as follows:

  • 2 cm or more in diameter in low-risk locations (areas L):
    • trunk and extremities, but not including the pretibia, hands, feet, ankles, and nail units.
  • 1 cm or more in diameter in moderate-risk locations (area M):
    • cheeks, forehead, scalp, neck, and pretibia.
  • The area H, independent of size:
    • The "mask area" of the face:
      • Central face, eyelids, eyebrows, periorbital, nose, lips (cutaneous and vermillion), chin, mandible, preauricular and postauricular skin/sulci, temple, and ear.
    • Genitalia, hands, and feet.

  2. My ex-husband and I had always managed to stay friendly after our divorce in February 2017. But I always wanted to get back together with him, All it took was a visit to this spell casters website last December, because my dream was to start a new year with my husband, and live happily with him.. This spell caster requested a specific love spell for me and my husband, and I accepted it. And this powerful spell caster began to work his magic. And 48 hours after this spell caster worked for me, my husband called me back for us to be together again, and he was remorseful for all his wrong deeds. My spell is working because guess what: My “husband” is back and we are making preparations on how to go to court and withdraw our divorce papers ASAP. This is nothing short of a miracle. Thank you Dr Emu for your powerful spells. Words are not enough. here is his Email: emutemple@gmail.com or call/text him on his WhatsApp +2347012841542

    He is also able to cast spell like 1: Lottery 2: Conceive 3: Breakup 4: Divorce 5: Cure for all kinds of diseases and viruses.
