The cure rate with Mohs surgery cited by most studies is between 97% and 99.8% for primary basal-cell carcinoma, the most common type of skin cancer. [2]: 13 Mohs procedure is also used for squamous cell carcinoma, but with a lower cure rate. Recurrent basal-cell cancer has a lower cure rate with Mohs surgery, more in the range of 94%.
Most small, low-risk and superficial skin cancers, such as basal cell carcinoma and squamous cell carcinoma, could be treated by curettage and electrosurgery. [6] A clinical margin which includes areas around the lesion site is marked out, and local anesthesia or numbing medicine is applied.
There is a risk of metastasis starting more than 10 years [citation needed] after diagnosable appearance of squamous-cell carcinoma, but the risk is low, [specify] though much [specify] higher than with basal-cell carcinoma. Squamous-cell cancers of the lip and ears have high rates of local recurrence and distant metastasis. [27]
Of nonmelanoma skin cancers, about 80% are basal-cell cancers and 20% squamous-cell skin cancers. [14] Basal-cell and squamous-cell skin cancers rarely result in death. [6] In the United States, they were the cause of less than 0.1% of all cancer deaths. [1] Globally in 2012, melanoma occurred in 232,000 people and resulted in 55,000 deaths. [6]
small-cell keratinizing squamous-cell carcinoma (code 8073/3) spindle-cell squamous-cell carcinoma (code 8074/3) It is also known as spindle-cell carcinoma, [23] and is a subtype characterized by spindle-shaped atypical cells. [24] adenoid/pseudoglandular squamous-cell carcinoma (code 8075/3) intraepidermal squamous-cell carcinoma (code 8081/3)
All squamous cell carcinoma lesions are thought to begin via the repeated, uncontrolled division of cancer stem cells of epithelial lineage or characteristics. Accumulation of these cancer cells causes a microscopic focus of abnormal cells that are, at least initially, locally confined within the specific tissue in which the progenitor cell resided.
Anal cancer is typically a squamous cell carcinoma. [3] Other types include adenocarcinoma, small cell carcinoma, and melanoma. [3] Diagnosis is suspected based on physical examination and confirmed by tissue biopsy. [1] Prevention includes avoiding risk factors and HPV vaccination. [6]
