Skin Cancer Non-Melanoma: High-Risk BCC/SCC
Reviewed by Oncology Team, VICI Healthcare | Last updated: 2026-04
What Non-Melanoma: High-Risk BCC/SCC Means
SCC: ≥4 mm depth, grade 3–4 differentiation, perineural invasion, or immunocompromised host. Location: ear, nose, lip, eyelid, genitals (anatomically high-risk sites). Basosquamous BCC.
Treatment Approach for Non-Melanoma: High-Risk BCC/SCC
Mohs micrographic surgery or wide local excision with adequate margins (5–10 mm). Sentinel lymph node biopsy if regional nodal involvement suspected. Adjuvant radiotherapy for perineural invasion, positive margins, or close margins. Advanced/metastatic disease: cemiplimab (PD-1 inhibitor) FDA-approved for advanced SCC. Follow-up: every 3 months for 2 years, then every 6 months.
Survival Rates and Prognosis
The 5-year survival rate for skin cancer at Non-Melanoma: High-Risk BCC/SCC is approximately 5-year recurrence-free survival: 50–80%; metastatic risk 5–20% for aggressive SCC variants. Survival rates are statistical averages drawn from large patient populations and may not reflect your individual outcome. Factors that influence your specific prognosis include your age, overall health, tumour biology, and how well the cancer responds to treatment.
Important: These numbers are drawn from historical data. Newer treatments available today may improve outcomes beyond what published statistics show. Discuss your individual prognosis with your oncologist.
