Non melanoma skin cancer ---> Basal cell carcinoma ---> metastatic risk
These include the following factors:
Recurrent tumor
Anatomic location
High risk: central face, eyelid, eyebrow, periorbital, nose, lip, chin, mandible, temple, ear, in front or behind the ear, genitalia, hand and foot
Medium risk: cheeks, forehead, scalp, and neck
Low risk: trunk, extremity (excluding hand/foot)
Size
Lesions +6 mm on high-risk area
Lesions +10 mm on medium-risk area
Lesions +20 mm on low-risk area
Histologic subtype pattern
Aggressive growth (morpheaform, fibrosing, sclerosing, infiltrating)
Micronodular
Ill-defined clinical borders
Perineural invasion
Development in sites of prior radiation
Immunosuppression

Adjuvant and Primary Radiation Therapy for nonmelanoma cancers
Non melanoma skin cancer ---> treatment of Non melanoma skin cancer ---> Radiation therapy
Radiation therapy may be useful for primary treatment of low-risk non melanoma skin cancers. In experienced hands, primary radiation therapy may also be useful for higher risk tumors with high cure rates. For cutaneous SCC with many high-risk factors and for those with extensive neurotropism, adjuvant prophylactic radiation therapy to the primary site and the primary draining lymph nodes may decrease the risks of local recurrence and regional nodal metastasis. Prophylactic adjuvant radiation therapy should also be considered for highly aggressive, deeply invasive BCCs that exhibit extensive neurotropism.

Treating BCC and SCC (Skin Cancer #6)
Skin cancer awareness ---> skin cancer videos ---> Non melanoma skin cancer ---> treatment of Non melanoma skin cancer
Basal cell carcinoma and squamous cell carcinoma are the two types of non-melanoma skin cancers. Luckily, there are many options for treating them.

Surgical Treatment of Nonmelanoma Skin Cancers
Non melanoma skin cancer ---> treatment of Non melanoma skin cancer ---> Non melanoma skin cancer Surgery
A skin biopsy for diagnosis is important before treatment of any skin cancer. Fortunately, most non melanoma skin cancers are small, low-risk lesions that respond with 90% to 95% cure rates to standard treatment techniques, including curettage and electrodesiccation, cryosurgery, radiation therapy, and surgical resection. Many skin cancers can be removed with elliptical excisions. Margins for low-risk SCC range from 0.5 to 1 cm. Margins for low-risk BCC range from 0.3 to 0.5 cm. Mohs surgery should be considered for BCCs and SCCs that exhibit the higher-risk factors. If Mohs surgery is not available, excision with careful frozen-section control (with permanent section confirmation) is indicated. The fundamental oncologic principle of tumor clearance first, reconstruction second should be followed.
