Skin is the largest organ of the body and is made up of various cells in constant motion. The skin is made up of three layers, including the epidermis, which is the top layer of the skin. The dermis is the second layer, thicker, while the last one is the subcutaneous layer. The epidermis provides protection to the body and gives color to the skin.
Skin cancer occurs as a result of abnormal growth of cells on the epidermis as a result of unrepaired DNA damage that causes a mutation in cells and results in their continuous growth leading to the formation of malignant tumors and cancer eventually.
