Basal Cell Carcinoma

Basal cell carcinoma: Basal cell carcinoma has a large number of cells that proliferate in an abnormal and uncontrollable manner. These cells aggregate to form tumors, which are malignant tumors. This is the most common type of skin cancer and can be described as a "slow growing" cancer that rarely spreads to adjacent sites to form more malignant tumors (Kumar et al., 2012: 864). Epidemiology information: People in contact with the sun are at risk of developing such skin cancer.

Skin cancer is the most common type of cancer and there are three main types of basal cell carcinoma, squamous cell carcinoma, and melanoma, both of which are named after the diseased cell types. Basal cell carcinoma is the most common and affects more than 4 million people each year in the United States alone - it can impair the appearance, but rarely threatens life. Squamous cell carcinoma affects more than 1 million people each year, and in the United States about 9000 people die each year. Melanoma is very rare but it is also fatal

Nonspecific features of Merkel cell carcinoma (MCC) lead to long-term differential diagnosis including basal cell carcinoma, squamous cell carcinoma, corneal adenoma, no melanoma, epidermal cyst, lymphoma, and skin metastasis. As a result, Merkel cell carcinoma (MCC) rarely is diagnosed before biopsy. Merkel cells are found on the skin of fish, amphibians, reptiles, birds and mammals. It is an oval or circular cell in the basal layer of the epidermis parallel to the surface. The cytoplasm of the cell is small, and the circular or elliptical nucleus has fine and uniformly dispersed chromatin. Cells accumulate in the sensory area such as the fingertip, nose tip, tactile follicle.

Merkel cell carcinoma is different from other types of skin cancer due to the type of cell involved. Merkel cell carcinoma occurs from Merkel cells. In contrast, basal cell carcinoma, the most common type of skin cancer occurs in the basal cells of the skin. Melanoma occurs from skin cells called melanocytes

Skin cancer is a malignant tumor of the skin and is the most common of all cancers. There are three major skin cancers: basal cell carcinoma, squamous cell carcinoma and melanoma. Basal cell carcinoma is the most common type occurring in the basal layer or the lower layer of the epidermis. Squamous cell carcinoma occurs in the upper layer of the epidermis. Melanoma occurs in melanocytes or pigment cells, the basal layer of the skin. Melanoma is the most dangerous type of skin cancer
