Basal-cell carcinoma. Basal-cell carcinoma (BCC), also known as basal-cell cancer, basalioma[7] or rodent ulcer, [8] is the most common type of skin cancer. [2] It often appears as a painless raised area of skin, which may be shiny with small blood vessels running over it. [1] It may also present as a raised area with ulceration. [1]
A basal cell is a cell type that is present in many forms of epithelium. It is generally located between the basement membrane and the rest of the epithelium. Examples include: The epidermal cell in the stratum basale. The airway basal cell, an epithelial cell in the respiratory epithelium. Basal cells of prostate glands.
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]
Medical genetics. Nevoid basal-cell carcinoma syndrome (NBCCS) is a rare inherited medical condition involving defects within multiple body systems such as the skin, nervous system, eyes, endocrine system, and bones. [1] People with NBCCS are prone to developing various cancers, including a common and usually non-life-threatening form of non ...
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%.
Basal cell carcinoma account for approximately 8% of all vulvar cancers. It typically affects women in the 7th and 8th decade of life. [22] These tend to be slow-growing lesions on the labia majora but can occur anywhere on the vulva. Their behavior is similar to basal cell cancers in other locations.

51,900 (2015) [9] Cutaneous squamous-cell carcinoma (cSCC), also known as squamous-cell carcinoma of the skin or squamous-cell skin cancer, is one of the three principal types of skin cancer, alongside basal-cell carcinoma and melanoma. [10] cSCC typically presents as a hard lump with a scaly surface, though it may also present as an ulcer. [1]
