of cells and their ultra structure The cell is the basic unit of life. Each cell can be regarded as a metabolic compartment‚ a separate place where the chemical processes of that cell occur. Cells are often designed to perform a particular function. Depending on that function‚ each cell type has an internal structure that suits it for its job. This is known as the ultrastructure of the cell. There are different types of cells inside the human body. They are the epithelial cells‚ muscle cells‚ nerve

that forms in the skin. There are three types of skin cancer; melanoma‚ squamous cell‚ and basal cell carcinoma. Out of the three skin cancers basal cell carcinoma (BCC) is by far the most common. BCC accounts for 90% of all skin cancers. Basal cell carcinoma is also the easiest to treat for the simple fact it rarely metastasize.
