Skin is the final layer and largest organ of our human system. Skin is made up of multiple layers of mesoderm tissues which protect our muscles, ligaments, bones and other internal organs lying underneath. Human skin is a thin layer which acts as a protecting agent from infections and pathogens, excessive water loss, and insulation. It regulates and maintains the human body temperature without any fluctuations.
Skin helps in sensation, synthesis, storage of vitamin D and vitamin B which helps in cell growth and reproduction, secretion of sweat. For breathing it absorbs small amount of oxygen, carbon dioxide and nitrogen. There are various skin types like oily, dry, normal, combination skin.
Skin is primarily composed of three layers. Namely epidermis, dermis and hypodermis. Epidermis is the outer layer which consists of basal and squamous cells. Melanocyte is a cell in the basal layer of epidermis. This produces melanin under the control of the melanocyte-stimulating hormone. It gives pigmentation to the skin which causes skin tanning. It also protects the deeper layer of the skin from exposure to UV light rays. The dermis which lies below the epidermis consists of blood vessels, connective tissues, hair follicles and the sweat glands.
The subcutaneous layer which is the deepest layer of the skin contains fat cells. Uncontrollable growth of abnormal cells in any layer of the skin ultimately leads to skin cancer. There are 3 common forms of skin cancer and these 3 are classified according to the types of cells affected. The most common form of skin cancer is called as basal cell carcinoma.
This is not a serious one but it requires treatment. This is quite common in the areas which are exposed to sunlight. However this doesn’t spread to other cells. Second form is Squamous cell carcinoma which develops in the middle layer of the epidermis. This is quite dangerous and it may lead to death if it is not treated properly. Third one is malignant melanoma which spreads quickly to other cells and causes quick damage. This type of skin cancer is dangerous if not detected and treated early. People with fair skin are at an increased risk for developing this form of cancer.
To prevent skin cancer better avoid exposing your skin to the sunlight between 10.00am to 4.00pm when the rays are at high intensity. In unavoidable conditions apply sunscreen lotions, Comfortable dressings to cover your hands, neck, face and head.
Surgery is the common treatment to overcome skin cancer diseases. However treatment depends on the patient’s age factor, overall health and medical history. Cancer stages also play a vital role in treatment. It takes about 28 to 35 days for the process of producing a new healthy skin.
