The body is made up of different types of cells that normally divide and multiply in an orderly way. These new cells replace older cells. In case of cancer, certain cells in the body have changed in appearance and function. They divide and grow in an uncontrolled way causing cancer. Skin cancer
is a disease where malignant cells are found in the epidermis (outer layer of the skin). Skin cancers can develop due to a continuous exposure to sun over the years.
Skin is the largest organ of the body and protects the body from injury and infection. It also regulates the body temperature and gets rid of waste substances through the sweat glands. Outer layer of the skin is called the epidermis and the layer underneath is known as the dermis. The epidermis contains the squamous cells, which are flat in shape. Below this layer are the basal cells, which appear round. In between these layers are the melanocytes, which produce the pigment, melanin that gives color to the skin.
